Full textAbstract:
Atlantic salmon (Salmo salar L.) has been domesticated since the 1960s and has undergone over 10 generations of artificial selection for economically important traits. As a result, domesticated salmon have diverged with respect to a number of phenotypic, genotypic and behavioural traits from their wild counterparts. Since the selection pressures that are present in the wild differ greatly from the ones that shape salmon under culture conditions, domesticated salmon stocks are considered to be maladapted to natural conditions. Despite strict regulations, insoluble issues pertaining to large-scale cage rearing of farmed fish mean that there is a continuous presence of farm escapees in the wild. Gene flow from escapees has been perceived as a factor in the decline of wild populations, suggested to occur through disruption of local adaptation. This study aims to improve understanding of the genetic differences between wild and domesticated stocks by comparing the transcriptomes of Figgjo (wild) and Mowi (domesticated) strains. A series of common garden experiments have been performed, utilizing pure and reciprocal hybrid crosses of the wild and domesticated stocks, reared under two different conditions and sampled at four time points and three distinct life stages (embryo, sac-fry and feeding fry). Microarray interrogations were performed employing a 44K custom microarray design to identify genes and gene pathways that are differentially expressed between the stocks. KEGG-based functional analyses have been implemented using different gene set enrichment packages, and dominance and additive parameters were calculated from normalized expression values to predict the mode of heritability of the genes identified as differentially expressed between stocks. Most biological functions represented in wild and domesticated crosses were consistent across life stages and environments. The transcriptomic differences detected between stocks in multiple developmental stages likely reflected adaptations to selection pressures differing between natural and aquaculture environments. Down-regulated environmental information processing and immune and nervous system functions in domesticated vs. wild fish may be due to local adaptation to captivity. These included reduced information acquisition and processing systems, altered stress responsiveness and changes in feeding behaviour. In line with the resource allocation theory of production trait animals, reduced immune function was coupled with increased expression of growth and development related pathways in domesticated salmon, compared to wild counterparts. Although there is support for this trade-off in all life-stages, resource allocation showed a shift over time; possibly reflecting variation in the utilization of energy sources during the transition from endogenous to exogenous feeding. Differences in cell communication and signalling pathways between wild and domesticated stocks, associated with organogenesis during the embryo stage, reflect sampling time and are indicative of altered organ development in response to domestication. Stress responses common across stocks included the down-regulation of cellular processes, including cell cycle and meiosis, and genetic information processing, such as replication and repair, transcription and translation pathways, probably reflecting the reallocation of energy resources away from growth and towards the restoration of homeostasis. Moreover, the mobilization of energy to cover the increased demands of maintaining homeostasis was indicated by the up-regulation of some metabolic pathways, mostly involved in energy, lipid and carbohydrate metabolism in response to stress. The analysis also revealed cross-specific stress responses, including indicators of a non-additive stress response in hybrid crosses. Most differentially expressed transcripts exhibited additive (31-59%) or maternal dominant (19-33%) inheritance patterns, although maternal over-dominance (23-26%) was also significant in the embryo stage. The mode of heritability of some immune transcripts was suggestive of maternal environmental influence having been affected by aquaculture. This study has demonstrated that biological functions affected by domestication include those associated with allocation of resources, involve reduction of information acquisition and processing systems and may lead to loss of local adaptation to wild conditions. Since such changes may affect key systems, such as immunity and responsiveness to stress, they can potentially have serious negative consequences under natural conditions. Transcriptomic differences observed between wild and domesticated stocks primarily exhibited additive and maternal dominant inheritance modes. Since gene-flow from farmed fish can be frequent and primarily concerns farmed females, this suggests that introgression due to repeated large scale escape events has the capacity to significantly erode local adaptation.

Full textAbstract:
In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen. This study investigated the difference in the proportion of fallbacks between early (June-July) and late (August-September) migrating salmons in 2011-2013. The results showed that there was a significant difference in the proportion of fallbacks between the early and the late-migrating salmon. Fifty-one percent of the early salmon and 13% of the late salmon fell back during these 3 years. Further, there was no significant difference between males and females that became fallbacks. Nor was there any difference in the length of early and late-migrating salmon or fallbacks and non-fallbacks.I sjön Vänern, Sverige, finns en endemisk population av Atlantlax (Salmo salar L.) som lever hela sitt liv i sötvatten. Laxen hindras från att migrera till sina naturliga lekplatser i norra delen av Klarälven av nio vattenkraftverk. Inget av vattenkraftverken har fiskvägar så att lax som migrerar uppströms eller nedströms kan passera. I dagsläget fångas lax som vandrar uppströms in i en fiskfälla vid det mest nedströms belägna kraftverket i Forshaga. Därifrån körs laxen i lastbil förbi åtta kraftverk och släpps ut några kilometer uppströms det åttonde kraftverket i Edsforsen. Den här studien undersökte skillnaden i andelen fallbacks mellan tidigt (juni-juli) och sent (augusti-september) migrerande laxar under åren 2011-2013. Resultaten visade att det fanns en signifikant skillnad i andelen fallbacks mellan den tidiga och den sent migrerande laxen. Femtioen procent av den tidiga laxen och 13% av den sena laxen föll tillbaka under dessa 3 år. Vidare fanns det ingen signifikant skillnad mellan hanar och honor som blev fallbacks. Det fanns inte heller någon skillnad i längden av tidigt och sent migrerande lax eller lax som föll tillbaka och lax som inte föll tillbaka.

Full textAbstract:
The aim of this dissertation is to trace the function of parody in the context of Salman
Rushdie&rsquos magical realistic fiction. The magical realism of Rushdie&rsquo
s fiction presents a complex Third World experience which constitutes an alternative to, and challenges the Eurocentrism of western culture. The form and content of Rushdie&rsquo
s novels are so intense and rich that the whole body of his work comes to the fore, not as an outcome of the two clashing civilisations, that is East and West, but rather as an immense medley of the two cultures. While &ldquo
writing back to the empire&rdquo
, Rushdie draws on innumerable sources ranging from such grand narratives as Genesis, Iliad, Ramayana, A Thousand and One Nights, Hindu, Persian, Greek, and Norse mythologies, and local cultural traditions, to modern politics mingling fiction and reality in a broad historical perspective, so that his work becomes a synthesis of East and West, an international aesthetic plane where diversities express themselves freely. The dissertation focuses particularly on Rushdie&rsquo
s Midnight&rsquo
s Children, The Moor&rsquo
s Last Sigh,and Shalimar The Clown.
it contains an introductory chapter, a theory chapter, including two subchapters, a development chapter with three subchapters which analyse the above mentioned three novels, and a conclusion chapter. The introductory chapter presents an overview of the issues to be investigated in the subsequent chapters. The theory chapter deals with the concepts of colonialism, nationalism, and the past and the present of postcolonial literary theory with reference to its leading theorists, such as M. Foucault, E. Said, H. Bhabha, and other recent critics
this chapter also introduces magical realism by reference to a number of current definitions and approaches. The following three subchapters, which focus on the analyses of the three novels, explore how parody functions both thematically and structurally in relation to Rushdie&rsquo
s magical realism. The concluding chapter demonstrates that Rushdie&rsquo
s work creates an unrestrained plane of an international culture where multiple visions and diversities can find a room to assert themselves.

Full textAbstract:
While much attention has been paid to the events which followed the publication of Salman Rushdie's The Satanic Verses (1988), there has been little detailed examination of the role of Islam in that novel and in the rest of Salman Rushdie's fiction, notably Midnight's Children (1981) and Shame (1983). His portrayals of Islam and Islamic societies are not easily recognizable via the traditional structures of the academic study of Islam. His divergence from the vast majority of Muslim tradition and experience can be seen firstly through his own experiences in India, England, and Pakistan; and secondly through his provocative literary exploration of religious beliefs, something which has few precedents in the history of Islam. By using Islamic elements and symbols in the same way that Western literatures have explored religious themes, Rushdie presents irreverent satire and often scathing criticism of many aspects of Muslim societies and culture. The most significant aspect of this critique is the attempt to subvert what Mohammed Arkoun called "Islamic logocentrism," the tendency to confine all discourse about Islam to a certain narrow field of textual interpretation. Rushdie's treatment of religion is informed by an ideal which sees reading and writing for one's own purposes to be the highest form of spiritual exercise, and when Islam is subordinated to the writer's imagination, he has little reason to uphold the authority or sanctity of its precepts, principles, or history.

Full textAbstract:
Salman Rushdie fait figure à la fois de théoricien et de praticien de l'hybridité. Ses romans, qui allient le réalisme à la magie, et le mythe à l'histoire, reflètent sa détermination à créer un langage et des formes littéraires susceptibles de rendre compte de l'expérience des peuples autrefois colonisés. Pour l'auteur, l'hybridité ne joue à plein que lorsqu'elle s'intègre dans une stratégie de subversion qui permet au colonisé de remettre en question le statut de l'autorité coloniale. Le terme "hybridité", qui renvoie implicitement à l'union d'éléments contradictoires, est essentiellement subversif et renvoie à un art que l'on qualifie généralement, et à juste titre, d'art de l'excès. Il désigne la transformation issue des combinaisons nouvelles et inattendues entre les êtres humains, les cultures, les langues, les idées ou encore les politiques, et est utilisé par Rushdie comme un synonyme de régénération, de nouveauté et de richesseSalman Rushdie occupies a unique position as theorist and practitioner of hybridity. His fiction, which combines history and myth, as well as reality and magic, is the result of his determination to create a literary language and literary forms in which the experience of formerly colonized people might find full expression. According to the author, hybridity only plays a full role when it is part of a strategy of subversion which enables the colonized to call into question the authority of the colonizers. The term "hybridity", which implicitly refers to the coming together of contradictory elements, is essentially subversive and carries within itself the seeds of an art, which is usually, and rightly, said to be an art of excess. It designates the transformation that comes of new and unexpected combinations (of human beings, cultures, languages, ideas, politics, etc. ), and is used by Rushdie as a byword for regeneration, novelty, and richness

Full textAbstract:
This dissertation explores the porous boundaries between Salman Rushdie's fiction and the various manifestations of the filmic vision, especially in Midnight's Children, The Satanic Verses, and other selected Rushdie texts. My focus includes a chapter on Midnight's Children, in which I analyze the cinematic qualities of the novel's form, content, and structure. In this chapter I formulate a theory of the post-colonial novel which notes the hybridization of Rushdie's fiction, which process reflects a fragmentation and hybridization in Indian culture. I show how Rushdie's book is unique in its use of the novelization of film. I also argue that Rushdie is a narrative trickster. In my second chapter I analyze the controversial The Satanic Verses. My focus is the vast web of allusions to the film and television industries in the novel. I examine the way Rushdie tropes the "spiritual vision" in cinematic terms, thus shedding new light on the controversy involving the religious aspects of the novel which placed Rushdie on the most renowned hit-list of modern times. I also explore the phenomenon of the dream as a kind of interior cinematic experience. My last chapter explores several other instances in Rushdie's works that are influenced by a filmic vision, with specific examples from Haroun and the Sea of Stories, "The Firebird's Nest," and numerous other articles, interviews, and essays involving Rushdie. In my conclusion I discuss some of the emerging similarities between film and the novel, born out of the relatively recent technology of video cassette recorders and players, and I examine the democratizing effects of this relatively new way of seeing.

Full textAbstract:
The objective of the work described in the current thesis was to provide a better understanding of some of the key factors associated with sea louse, Lepeophtheirus salmonis, infection of farmed Atlantic salmon. In Chapter 2, initial work focused on establishing the vertical and horizontal distribution of sea lice copepodids and spatial patterns of on-farm infections. The louse distribution was investigated along the main current gradient across adjacent salmon production pens at three commercial sites. A depth profile for the distribution of larval lice was also established for the top 12 m of the water column at three different locations in close proximity to commercial salmon farms. Within all multi-pen sites there were clear patterns of distribution and infection along the main water current gradient with the abundance of lice in end pens at each site appearing to be different from the central pens. The vertical distribution pattern of free swimming L. salmonis larvae (nauplii and copepodids) showed that the surface 6 m harboured 85.5 ± 1.6 % of the lice present in the water body analysed (0 – 12 m depth), irrespective of sampling date and location. In Chapter 3, further environmental effects / influences on attachment success of the copepodids were analysed using controlled infection challenges. A flume with adjustable flow rates, and controlled light conditions was designed for this study. Flume current velocity was observed to be a significant factor in infection success, with higher infection levels observed at lower current velocities, while higher current velocities were demonstrated to reduce settlement success. At fixed velocity, higher copepodid exposure levels gave rise to higher infection levels, this having a linear relationship suggestive of a lack of competitive effects for space on the fish. Light was also shown to play an important role in host settlement. A positive correlation between increasing light intensity and higher louse attachment success was found for all tested light spectra / wavelengths (white - Halogen, blue 455 nm, green 530 nm and red 640 nm). Observation of an infecting cohort of copepodids showed maximal infection at four days post-moulting with a tail-off of infection by six days post-moulting. However, even under the optimal conditions represented by a flume challenge, including linear water flow, the constraint of copepodids to pass close to the salmon host and the very high exposure levels of copepodids per fish, louse attachment success was still relatively low. Chapter 4 examined implementation of a possible management approach based upon some of the environmental influences observed. This chapter described a study in which environmental manipulation of salmon swimming depth was employed on-site in an attempt to reduce farm infection of Atlantic salmon. The effects of submerged artificial lighting in combination with submerged feeding were tested with respect to salmon swimming depth and sea lice infection, following the hypothesis that L. salmonis infection in a commercial salmon population could be reduced through exposure to deep lighting and feeding. The results of the study suggest that swimming depth manipulation can indeed be used at a commercial scale to reduce salmon lice burdens on Atlantic salmon by physically minimising spatial interactions between the two animals. In the final research chapter (Chapter 5), this thesis examines the question of whether ploidy of the host impacts on sea louse infection levels and whether susceptibility of individual fish is consistent between replicate infections. Results showed that triploid salmon are not subject to higher sea louse infection levels under experimental challenge and farm infection conditions compared to diploid hosts. In addition, triploid fish subject to initial infection, did not become more or less resistant to infection compared to diploids when comparing repeated sea louse infections. In summary, this thesis describes work conducted to analyse key infection pathways and factors influencing infection of Atlantic salmon by sea lice and suggestions made as to how findings may be exploited to reduce louse burdens in Atlantic salmon farming. The practical solutions presented to exploit the results found in this work are currently under consideration by the Scottish salmon industry.

Full textAbstract:
This is a new study of Salman Rushdie's fiction, reading his texts through translation theory. Going beyond previous studies of Rushdie's writing, the majority of which have been postcolonial critiques, or have aimed to illuminate obscure references, my study engages with those images which are interesting to postcolonial studies and reads them through their relevance to the theory of translation. Engaging with texts on translation including those by Walter Benjamin, George Steiner, Lawrence Venuti, Andre Lefevere, Susan Bassnett and Harish Trivedi, as well as other theoretical perspectives (including postcolonial, postmodern, and linguistic theory), my study equally interrogates Rushdie's fiction and related aspects of translation theory. My thesis begins by examining images of the harem and the veil and suggests that these images denote the untranslatable. Further chapters suggest that the figure of the translator is a transgressor, and that transgression is necessary in order to translate. Ideas of linguistic creativity, clumsiness, slang, and bad language in the novels are opposed with the translator's goal of textual perfection. I examine the prophetic angel figure as an example of miscommunication, suggesting the relationship between translation and prophecy. Other disruptions to communication include those caused by the temptations of food, and the madness which Babel causes, and which may be dispelled with the advent of a post-translation, unilingual, utopian future. The final chapter suggests that the short story form (a less studied part of Rushdie's bibliography) provides a solution to problematic translations because of the nature of the narrator's voice in the short story which employs direct communication with the reader.

Full textAbstract:
Considering the response of organisms to their environment is difficult; it is made more so if population numbers cannot be closely monitored. In such cases different methods of population assessment are required. This thesis uses lipids as a measure of Atlantic salmon (Salmo salar L.) quality and investigates its usefulness in indicating fish condition. The first study examines the relationship between fish total lipid content and W[sub]R condition factor; this study clearly demonstrates that there is a significant positive relationship between the condition factor of a fish and its total lipid content. In the following study the lipid storage between the different tissues of the Atlantic salmon is considered. This indicates that the red muscle and the adipose tissues hold higher concentrations of lipid than the white muscle. However, the white muscle makes up the majority of lipid tissue mass in the Atlantic salmon so contains the bulk of stored lipid in a fish, at low concentration. The next study investigates the effect of spawning on Atlantic salmon condition. Salmon can be seen preferentially conserving lipid in their musculature and drawing down the lipid stored in their adipose tissues. The following study looked at one key lipid group, triacylglycerides, in salmon. Triacylglycerides are energetically important in fish and this study found that the spawning process depleted triacylglyceride reserves, but that the red muscle conserves triacylglycerides even after spawning. The final study considers the relationship between maternal quality and egg quality, identifying that longer Atlantic salmon produce eggs with more lipid after spawning migration. Egg lipid concentrations were comparably maintained between fish. Monitoring quality in this way is a useful tool to determine population wellbeing and help indicate where populations are compromised.

Full textAbstract:
Photoperiod manipulations are widely used throughout the Atlantic salmon (Salmo salar) farming industry as a means of producing a product of uniform quality all-year round. However, farmers still remain sceptical over their effectiveness to regulate growth and maturation during the on-growing stage. Furthermore, reports of a characteristic growth-dip following light exposure suggest that light may negatively affect the physiological performance of fish in the short-term. Thus, this thesis investigates the effects of light characteristics (spectral quality, intensity and photoperiod) on growth and maturation of salmonid fish and addresses some of the uncertainties surrounding photoperiod use currently reported within the industry. Rainbow trout (Oncorhynchus mykiss) are seemingly an ideal model species for examining photoperiod effects on growth. Consequently, the application of constant light exposure (LL) at two different intensities (28W and 16W) during two different thermal conditions (summer and winter) was examined on individually tagged fish. Feed intake and growth appeared to be related to the ambient water temperature and did not appear to be affected by intensity or photoperiod, although the onset of constant light did appear to initially affect growth rate. This may indicate that LL has a limiting effect on the growth of trout or that the prevailing water temperature at which light is applied may override the photoperiodic effect. Furthermore, the lack of enhanced growth in trout exposed to LL, unlike that demonstrated for other salmonids, suggest that there may be a species-specific response to environmental variables. Thus, questions regarding photoperiod effects should be limited to the species in question. The main source of variation in results observed under photoperiod manipulations stems from the salmon industry. Atlantic salmon post-smolts were reared in seawater tanks and either maintained under a natural photoperiod (NP) or exposed to a simulated natural photoperiod (SNP), constant light superimposed on the natural light (NPLL) or constant light only (LL). Artificial light onset, irrespective of photoperiod, resulted in an apparent trend for a reduced appetite lasting up to 60 days. Furthermore, the onset of constant light resulted in a significant chronic elevation of plasma cortisol levels and changes to growth and thyroid hormone levels, providing direct evidence that constant light exposure induces stress. In addition, fish exposed to SNP failed to exhibit a stress response despite a low feed intake. However, differences in the plasma melatonin levels during twilight times, as compared to NP, suggest that gradual changes in the natural light intensity throughout the day, particularly around dawn and dusk, may be important for synchronizing daily events. No differences in growth were observed between the NP and NPLL regimes, although fish reared in an enclosed regime (SNP and LL) exhibited a significantly lower weight gain than fish in an open environment (NP and NPLL). This further highlights the impact that the rearing environment has on the growth performances of fish and the need for commercially run trials. Advances in lighting technologies and a greater understanding of how light is transformed through the water column have focussed research on the spectral sensitivity of fish. Therefore the lighting efficiency of novel blue narrow bandwidth LED lighting units through the water column and their effects on growth and maturation performances of salmon reared in commercial production cages were compared against the standard metal halide units currently utilized throughout the industry. LL application, irrespective of intensity or spectrum, reduced the numbers of fish maturing as compared to fish reared under a natural photoperiod. However, this was greatest under the standard metal halide units reflecting a greater light penetration and perception as determined by plasma melatonin levels. The metal halide groups exhibited the greatest relative weight gain over the trial period as compared to control fish. No evidence was observed for a growth-dip under metal halide light, although blue lit treatments exhibited an initial significant reduction in food consumption, suggesting a possible welfare issue. Nevertheless, the prototype blue LED units showed possible potential for commercial application by penetrating the water depth at half the distance of the metal halide units for only one eighth the power and one fifth the brightness. However, further tests of these prototype spectral units are required to examine the potential welfare and physiological growth and reproductive effects. These studies have shown that the efficacy of artificial light regimes is largely dependent upon the effectiveness of the light source through the underwater environment and its perception by fish, providing a sufficient intensity is emitted exceeding the physiological threshold level for the species cultured. Moreover, whilst the onset of artificial light may elicit a stress response and demonstrate a trend for a suppression of appetite for salmon reared in experimental tanks, no compelling evidence for a suppression of appetite or growth was found under normal commercial cage conditions. This suggests that the growth-dip observed within the industry may in part be a combination of a physiological response to the onset of light further exaggerated by the farmer’s perception and altered judgement in feeding. In addition, the results obtained from this study have helped to standardize the use of light regimes within the industry. Nevertheless, further studies are necessary to fully elucidate the underlying mechanisms which may govern growth and maturation in fish following the onset of light exposure.

Full textAbstract:
Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. This makes management and conservation a complex task requiring knowledge of salmon ecology at different temporal and spatial scales. In this thesis I highlight the use of a holistic life-history based approach in the conservation and management of wild and hatchery-reared salmon in regulated rivers and lakes. Small populations of wild-reproducing landlocked salmon and trout Salmo trutta exist in the regulated River Klarälven, Sweden. Since the 1930s, transportation of adult spawners upstream of eight dams has given the fish access to spawning grounds. The number of returning wild spawners became critically low in the 1960s, but stocking of hatchery smolts resulted in an increase in spawners that continues today. My data show that wild smolt may suffer high mortality due to multiple dam passages. To ensure viable populations of wild populations, future management should include both up- and downstream solutions that ensure connectivity in the system. The recreational and commercial salmonid fishery are maintained by compensatory stockings, yielding annual catches of about 75 tons, and a river return rate of hatchery fish of about 1%. As a large portion of the stocked smolts does not survive downstream migration to the lake, there has been discussion about the quality of the stocked smolt and about stocking strategies. Based on my studies, producing hatchery smolts more closely resembling wild-born conspecifics should result in reduced loss rates. I suggest changes in the hatchery and stocking procedures to increase the survival of stocked smolts. The results of my research should be applicable to other regulated systems, particularly those with mixed stocks of wild and hatchery salmonid populations.Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes, which make management and conservation a complex task requiring knowledge of salmon ecology at different temporal and spatial scales. In this thesis, I highlight the use of a holistic approach in the conservation and management of wild and hatchery-reared salmon in regulated rivers and lakes. Small populations of wild-reproducing landlocked salmon and trout Salmo trutta exist in the regulated River Klarälven, Sweden. Since 1930, transportation of adult spawners upstream of eight dams has been done to give the fish access to the spawning grounds. My data indicate that a large proportion of the wild smolts are lost due to multiple dam passages, and future management should include both up- and downstream solutions, ensuring connectivity in the system. The fishery in Klarälven and Lake Vänern is maintained by compensatory stockings, yielding catches of about 75 metric tons and a river return rate of stocked fish of about 1%. I suggest changes in the hatchery and stocking procedures to increase the survival of stocked smolts.

Vattenkraften har en negativ miljöpåverkan på flera sätt, inte minst genom fragmentering av vattendrag. Därför är det viktigt att studera åtgärder som potentiellt minskar vattenkraftens inverkan. Här undersöktes experimentellt avledningseffektivitet och tidsåtgång för nedströmsvandrande atlantlaxsmolt hos låglutande avledare i en strömränna. Smolten startade uppströms om anläggningen och registrerades ifall de besökte flyktöppningarna i passagelösningen för nedströmsmigrerande fisk. Inom båda huvudtyperna, α- och β-avledare, testades tre olika avledare vardera där α-avledarna bestod av galler med spaltvidderna 15, 18 och 30mm. β-avledarna innefattade två galler med spaltvidderna 15 och 30 mm samt ett kevlarnät med entumsmaskor. Resultaten visade att hos α-avledare hade spaltvidden hos gallret betydelse för effektiviteten mellan största och minsta gallret. Mellan β-avledarna med 15 och 30 mm spaltvidd hade spaltvidden ingen betydelse varken för avledningseffektivitet eller tid till passage. Däremot var entumsnätet mindre effektivt. Resultaten indikerade att β-avledare var generellt mer effektiva än α-avledare med högre avledningseffektivitet, möjligen på grund av olikheter i konstruktionerna av flyktöppningarna i anslutning till avledarna. Resultatet pekar också på att β-galler kan ge upphov till en beteenderespons hos smolten som inte registrerades hos α-galler.Hydropower has a negative environmental impact in several ways, not least through fragmentation of watercourses. This makes it important to study measures that potentially reduce the impact of hydropower. Here, diversion efficiency (passage) and time spent migrating by Atlantic salmon smolts was tested experimentally in a flume equipped with low-slope diverters, simulating passage of a hydropower plant. The smolt were released upstream of the facility and were registered if they visited the entrance to the flume’s passage solution for downstream migrating fish. In both main types, α- and β-diverters, three different diverters were tested each, where the α-diverters consisted of bar racks with gap widths of 15, 18 and 30mm. The β-diverters included two bar racks with gap widths of 15 and 30 mm and a kevlar net with 25 mm meshes. The results showed that in α-diverters, the gap width of the racks was important for the efficiency between the largest and smallest gap widths. Between the β-diverters with 15- and 30 mm gap width, the gap width had no significance either for efficiency or time to passage. However, the one-inch net was less efficient. The results indicated that β-racks were generally more efficient than α-racks with higher diverting efficiency, possibly due to differences in the constructions of the escape openings adjacent to the diverters. The result also suggests that β-racks may give rise to behavioral responses in the smolt that was not registered in α-racks.

Resumo: A tese discute a construção narrativa dos romances Os filhos da Meia-Noite, Os versos satânicos e O último suspiro do Mouro, do escritor indo-britânico Salman Rushdie, tomando por base as propostas teóricas da literatura contemporânea e relações com o pós-colonialismo. Esses romances rejeitam a hegemonia das forças totalizadas do pensamento institucionalizado que violam a individualidade humana e das minorias que seguem caminhos contra o conformismo. Ao analisar a obra de Rushdie, destacamos que, apesar de sua narrativa se fazer através da língua inglesa, estão presentes na sua estrutura discursiva as forças culturais da sociedade oriental e ocidental. As histórias contadas por Rushdie são histórias outras que, por meio de um espectro narrativo envolvente, contam a história daqueles que vivem sob o domínio do silêncio.
Abstract: This thesis discusses the narrative construction present in the novels Midnight¿s Children, Satanic Verses and The Moor¿s last Sigh, written by the Indo-British writer Salman Rushdie based on the theoretical proposals of the contemporary literature and their relationship with the post-colonialism. The aforementioned novels reject the dominating forces¿ hegemony of the institutionalized thinking that violates in the human individuality and the minorities that choose a path against the conformism. By analyzing Rushdie¿s works we highlight that, despite the fact his narrative is in English, the cultural forces of eastern and western are present in his discursive structure. Through fiction, it is also possible to possess means of apprehending the legacy of the Indian colonization. The stories told by Rushdie are stories that, through a compelling narrative spectrum, tell the story of those who live under the domination of silence.

Full textAbstract:
Cette these explore le travail de creation romanesque de salman rushdie. La lecture de son Œuvre de 1981 a 2005 (romans, nouvelles mais aussi essais, selection d'articles et d'entretiens) revele un ecrivain qui developpe une " poetique du passage " et la theorise. Endossant les roles de conteur, d'historien et de satiriste, le romancier cree un espace proteiforme de reflexion sur les representations (en particulier, l'histoire, les arts et les recits sacres). Cette poetique se construit dans une tension entre l'Œuvre romanesque et le statut d'intellectuel de rushdie dans le monde contemporain. La lecture croisee des romans et des essais montre comment la poetique du passage se renouvelle au fil des annees pour accommoder un ensemble de traditions et de conventions. Dans les romans, l'omnipresence des figures de l'autorite, politique, familiale et religieuse, laisse entrevoir deux modes, ludique et satirique, selon lesquels l'autorite est tour a tour admiree, haïe, subvertie et remplacee. Enfin, l'Œuvre s'inscrit dans des logiques d'affiliations et de consecration, auxquelles rushdie contribue lorsqu'il critique, edite des anthologies, consacre a son tour d'autres ecrivains pour inflechir le cours de l'histoire litteraireThis dissertation explores salman rushdie's novelistic creation by reading his texts written from 1981 to 2005 (novels, short stories, but also essays and a selection of articles and interviews). The "passage" characterizes the poetics 0f rushdie, who, in turns, theorizes it. At once a storyteller, a historian and a satirist, the novelist creates a protean novel in order to question representations (especially history, arts and sacred texts). This poetics builds itself around a tension between the novelistic work and rushdie's status as an intellectual in the contemporary world. A cross-reading between novels and essays shows how the "poetics of the passage" renews itself in the studied time period. Internally, the multiplicity of authoritarian figures (political, familial and religious) in the fiction reveals two different modes (playful and satiric) according to which authority is at once admired, hated, subverted and replaced. Externally, rushdie's texts can be read according to the principles of affiliation and consecration, to which the author contributes when he reviews, edits an anthology or consecrates other writers in order to influence the course of literary history

Full textAbstract:
Né en Inde, puis émigré en Grande-Bretagne, Salman Rushdie est devenu, depuis la publication des Enfants de minuit en 1981, l'un des chefs de file de la littérature indo-angliane ; littérature qui s'est principalement donnée pour mission de mettre en lumière les paradoxes inhérents à l'écriture " du retour ", issue de la théorie postcoloniale. Rushdie reste un exemple fascinant de ces contradictions, lui qui a choisi de quitter l'Inde puis, à la suite de l'exil forcé dans son propre pays d'adoption en 1989 par la fatwa (qui le condamnait à mort pour propos blasphématoires), a fini par réapprendre la nostalgie de ses origines. Car il est certes vrai que, si les menaces ont depuis été levées, et que l'écrivain a choisi d'émigrer de nouveau vers l'ouest, à New York, la condition exilique de l'homme imprègne encore et toujours son œuvre, et il ne peut se résoudre à dire définitivement adieu à l'Inde. Rushdie est donc, à ce titre, un représentant emblématique de la désorientation postcoloniale, qui envahit ses récits : une perte des repères notamment caractérisée au niveau narratif par certaines thématiques récurrentes, telle que la migration, les vérités multiples, et la célébration de l'hybridité par le mélange savant de références orientales et occidentales - des thèmes qui correspondent manifestement aussi aux préoccupations de la littérature postmoderne. Ce que l'on retrouve en filigrane dans sa prose, ce sont donc ses contradictions d'homme postcolonial, pour qui les nombreux mouvements migratoires entre Orient et Occident occasionnent aussi des mutations identitaires successivesBorn in India, then emigrated to Great Britain, Salman Rushdie became, after the publication of Midnight's Children in 1981, one of the leaders of indo-anglian literature ; a literature which main mission is to highlight the paradoxes intrinsic to postcolonial writing, meant to " write back ". Rushdie remains one most fascinating example of these contradictions, as he chose to leave India and then, after his forced exile in his own country of adoption in 1989 because of the fatwa (which condemned him to death and was pronounced for blasphemy), learnt back the nostalgia for his origins. It is certainly true, at any rate, that if he is no longer under threat, and that he has chosen to emigrate again to the west (to New York), the exilic condition of this man still pervades until today his work and he is unable to say definitely goodbye to India. Rushdie is, then, an emblematic representative of postcolonial disorientation, which invades his stories : a loss of landmarks characterized on the narrative level for instance by some recurring themes, such as migration, multiple truths, and a celebration of hybridity by the clever mingling of oriental and occidental references - such themes that obviously correspond as well to the preoccupations of postmodern literature. What is to be found just beneath the surface of his work is, then, the contradictions of his postcolonial self, for whom numerous migratory movements between Orient and Occident also bring about successive identity mutations

Full textAbstract:
Leptin is a peripheral adiposity signal and a key hormone in energy balance regulation in mammals, acting as a link between nutritional status and the endocrine reproductive axis. If this is also the role of leptin in fish is not fully understood. This thesis investigates how different components of the leptin system are affected by sexual maturation and seasonal changes in energy balance in male Atlantic salmon (Salmo salar L.) parr under fully fed and feed-restricted conditions. Moreover, the role of sex steroids as being one of the possible mechanisms by which sexual maturation interacts with leptin is explored. The salmon leptin-a genes, lepa1 and lepa2, were expressed mainly in liver and the leptin receptor (lepr) in brain and ubiquitously in peripheral tissues. Seasonal characterization of the lepa genes and lepr during the growth and reproductive season in one-year old males showed that hepatic lepa1 and lepa2 mRNA levels and plasma leptin levels were down-regulated concomitantly with an increase in weight and body fat. Feed restriction up-regulated hepatic leptin, and pituitary lepr expression as well as plasma leptin levels. Correlation between leptin levels and body lipid stores were either lacking or negative. These findings show that leptin and lepr are sensitive to changes in energy balance, but that leptin might not reflect adiposity in juvenile salmon. Hepatic lepa1 and lepa2, and testicular lepr expression increased during mid- to late spermatogenesis in early maturing males. This up-regulation was preceded by rapid gonadal growth and elevated pituitary follicle-stimulating hormone gene expression levels, whereas peak leptin levels coincided with peak pituitary luteinizing hormone expression and the presence of running milt in the testes. The sex steroids testosterone (T), 11-ketotestosterone and 17-β estradiol stimulated lepa1 and lepa2 gene expression in Atlantic salmon hepatocytes in vitro differentially depending on developmental stage. T was also able to stimulate hepatic lepa1 and pituitary lepa1 and lepr gene expression in immature male salmon in vivo. These results suggest that leptin plays a role in male fish reproduction during later stages of the maturational process and that the elevation of leptin expression during spermatogenesis could be caused by androgen stimulation.

Full textAbstract:
This thesis argues that the shortcomings of modernist liberal defences of Salman Rushdie's The Satanic Verses have helped to draw debate over the book into a stalemate. It also attempts to demonstrate how aspects of this stalemate might be broken. Chapter One contains a brief philosophical survey of the debate, juxtaposing the framework relativism propounded by Rushdie and many of his advocates with the absolutism of Rushdie's Muslim detractors. The chapter closes with an analysis of the contradictions present in Rushdie's relativistic defence of his novel.Chapter Two opens with a short argument against existing blasphemy laws. The philosophical sketches in Chapter One are applied to the contents of the novel itself, producing an outline of the contending views of "literary contest" and "authorial intention" held by the two sides in the debate, and illuminating Rushdie's apparent confusion about the purposes of his novel.
Chapter Three proposes a solution--based on philosopher Alasdair McIntyre's thought--to defects in modernist liberal defences of The Satanic Verses.

Full textAbstract:
The twenty-first century has seen a resurgence of academic interest in biopolitics: the often oppressive political power over human biology, human bodies and their actions that emerges when political technologies concern themselves with and act upon a population as a species rather than as a group of individuals. The publication of new works by theorists including Michel Foucault, Giorgio Agamben, Roberto Esposito, Michael Hardt and Antonio Negri has furthered academic understanding of biopolitical attempts to ensure an orderly, productive society. Biopolitics bases these attempts upon optimising the majority population’s health and well-being while constructing simultaneously a subrace of unruly, unproductive bodies against which the majority requires securitising. However, despite the still-proliferating and increasingly diverse recent theoretical work on the subject, little material has appeared examining how literature represents biopolitics or how theories of biopolitics may inform literary criticism. This thesis argues for Salman Rushdie’s novels as an exemplary site of fictional engagement with biopower in their portrayal of the increasingly intense and pervasive biopolitical technologies used in the twentieth and twenty-first centuries. Rushdie has been considered frequently as a novelist who explores political discourses of race and culture. However, analysis of the ways in which he depicts these discourses animating recent biopolitical practices has proven scarcer in Rushdie Studies. This thesis asserts that Rushdie’s novels affirm consistently the desirability of non-racialising polities, but almost always suggest little possibility of constructing such communities. In the process, it will reveal that he represents more numerous and varied forms of racialisation than has been supposed previously. This study considers how Rushdie describes biopolitical racialisation by state and superrace alike, the massacres of subraces that often ensue, how biopower operates and is resisted in space, and the discursive and practical forms this resistance takes. Contrasting Rushdie’s early fiction with his less-studied more recent works, this analysis deploys, critiques and augments canonical theories of biopower in order to chart his generally growing disinclination to depict this resistance’s potential success. This study thus works towards a new biopolitical literary criticism which argues that although the theories of Foucault and others illuminate the ways in which literature represents power and resistance in contemporary politics, narrative fiction indicates simultaneously the limitations of these theories and the practices of resistance they advocate.

Full textAbstract:
Salman Rushdie’s The Satanic Versesis one of the most controversial postcolonial novels, which among a plethora of themes seems to mainly focus on the notion of hegemonic power. The Satanic Verses can partly be read as a denunciation of the British hegemony in which social injustice, racial discrimination and violence, in its different forms, exerted upon marginalized and stigmatized people (such as non-European expatriates) are legitimized by the dominant group and understood as something conventional and normal by the subjugated people. Moreover, this novel encourages the readers to criticize religion as a political tool with the help of which the dominant group can make groups of people subservient to authority. This part of my essay is related to the criticism of hegemony as such. Employing Gramsci’s analysis of hegemony, this paper begins with an investigation of the relationship between the figure of a migrant, violence and cultural hegemony inRushdie’s Britain. In the second part, the link between dream scenes and the ways through which they contribute to the overall argument about hegemony is studied. Finally, the last part of this essay revolves around religious hegemony. Hence, what links all these three sections together is the concept of hegemony and the ways through which hegemonic power is achieved and implemented in this novel.

This literary analysis focuses on gendered constructions of masculinity in The Satanic Verses by Salman Rushdie. The main argument is that masculinity is a construction of gender much like femininity. Masculinity, however, has often been disregarded as an approach within gender studies of literature where the aspects of femininity have taken precedence. The theoretical approach in this analysis is the sociological perspective of gender, not determined solely by the biological sex. I will discuss sociological gender, and the constructions of masculinity, from the following five aspects: the male body, sex, fatherhood, violence and performance. I will address the physical mutations of the protagonists’ bodies, the sexual relationships between the characters as well as the reproductive organ and its contextual meaning. I will also focus on the ideas of, and relations to, fatherhood, violence the characters are subjected to, as well as the performance of acting your identity. All of these five aspects show constructions of masculinities clearly, and there is a need for addressing them more thoroughly in literary analyses.

Full textAbstract:
Among efforts to develop sustainable approaches towards the intensive rearing of finfish within open marine waters, is the development of integrated aquaculture techniques. Integrated Multi-Trophic Aquaculture (IMTA), has been promoted as a way to reduce unwanted environmental impacts associated with the intensive production of marine finfish within net-pens. The principle aim of this concept, is the bioremediation of nutrient discharges from fish aquaculture. This is to be achieved by integrating fish cultivation with the growing of species from lower trophic levels, which use the nutrient discharges as a food source. Many studies have been performed that investigate the ability of various species of macroalgae to remove dissolved nutrient discharges, and the ability bivalves to remove solid-bound nutrients, presented as either fish faeces, or an enhanced production of phytoplankton that may be promoted by nutrients emitted by fish-farms. IMTA has also been suggested as a means to improve overall productivity per unit of feed applied to fish, through the conversion of nutrient emissions into additional biomass, such as the tissues of macroalgae or bivalves. Within the research community which focuses upon the environmental impacts of aquaculture, there is a growing awareness that sustainable solutions to aquaculture production cannot be realised through a focus restricted to the growing-phase, and to a limited set of environmental impacts which may this activity may produce. This is because changes to a specific production phase often promote changes at phases located elsewhere along a products value chain. Life-Cycle Assessment (LCA), is a method employed for modelling the environmental impacts that may potentially be generated across the value chain of a product. It is particularly useful for identifying instances of environmental impact shifting; a term used to describe situations where efforts to reduce the contribution of a specific production phase towards one or more environmental impacts, has the effect of either displacing this contribution to another phase, or increases the contribution of production towards different environmental impacts. Despite its apparent suitability, LCA has not previously been fully applied to the environmental impact modelling of open-water IMTA systems. The work presented in the following thesis advances this research front, by using LCA to explore the potential for environmental problem shifting occurring as a consequence of replacing intensive monoculture production, with IMTA. Comprehensive datasets have been acquired from the Chilean aquaculture industry, describing the production of aquafeed and Salmo salar, as well as for the production of the Phaeophytic macroalga, Macrocystis pyrifera, and the molluscan bivalve, Mytilus chilensis. Using LCA methodology, the production of salmon feed, and the production of S.salar, M.pyrifera and M.chilensis, have been assessed for their capacity to contribute towards a variety of global-scale, environmental impacts. IMTA consisting of either S.salar and M.pyrifera, S.salar and M.chilensis, or all three of these species, and combined at ratios required for a bioremediation efficiency of 100 %, 50%, or 20 % of either nitrogen or phosphorous emission from fish, is compared to the monoculture production of S.salar. The comparison is based upon a standardised functional unit, with each species produced through IMTA, being modelled as part of the reference flow required to fulfil the functional unit. Monoculture is compared to IMTA upon the basis of nutritional function, by using a functional unit of mass-adjusted protein content, and mass-adjusted economic value. The use of economic value is based upon the ‘best-case’ assumption, that it serves as a proxy for the total nutritional function that each product offers to human society. The LCAs presented in this study have produced a number of results. Salmon ingredients derived from agricultural crops and animals account for the majority (between 71 % to 98 %) of contributions towards the impacts of compound salmon feed. In general, agricultural crops ingredients contribute more to these impacts than do agricultural animal ingredients, and account for between 31 % and 87 % of the contributions from all ingredients and inputs. In contrast, the combined supply of fish meal and fish oil from capture fisheries is responsible for between 0.13 % and 11 % of all impacts. Vegetable oil accounts for the vast majority of contributions from ingredients derived from agricultural crops. Vegetable oil is modelled as a 50 : 50 blend of sunflower oil and rapeseed, oil, but sunflower oil accounts not only for most of the contributions from vegetable oil, it is responsible for over 50 % of the contributions that all agricultural crop based ingredients contributes towards some impact categories. Replacing sunflower oil with rapeseed oil reduces the contributions of salmon feed by between 6 % and 24 % across 10 out of the 11 impact categories. When compared upon the basis of equal weight, the contributions of fish oil are between 18 % and 99 % lower than those from rapeseed oil. The production of feed is responsible for the majority of contributions (between 32 % and 86 % ) to all impacts of salmon grow-out production. The production of salmon-smolts accounts for between 3 % and 18 %. The majority (64 %) of contributions towards the eutrophication potential of salmon production are from nutrient emissions, which are the result of fish metabolism, whilst nutrients released through the production of feed, the majority of these being from the agricultural production of crop and animals, account for 32 %. Feed production is also a major contributor to the impacts of land-based smolt production, but these contributions (between 12 % and 37 % across all impact categories) are of a lower magnitude than those from the supply of feed to the grow-out phase. Inputs of salt, and inputs of both electricity produced in a diesel power generator and obtained from the national electricity network, are also notable contributors (between 5 % and 67 %, 4 % and 29 %, and 2 % 47 %, respectively) towards the impacts of smolt-production. The main contributors towards the potential impacts of kelp grow-out production (excluding eutrophication potential) are the supply of infrastructure (between 14 % and 89 %), operation of a diesel-powered motorboat for maintenance purposes (between 1 % and 89 %), and the supply ‘of seeded cartridges’ (between 9 and 49 %). The major contributors from the production of ‘seeded cartriges’ in a land-based facility are the supply of electricity from the national electricity network, the supply of fresh water, and the treatment of waste water. The impact potentials of producing seed in this facility might be reduced if the scale of operation is increased. Removal of nitrogen and phosphorous upon the harvesting of kelp is calculated based upon kelp tissue contents of these nutrients. The harvesting of 200 tonnes ha / yr-1, results in a eutrophic potential with a negative value (-376.51 kg of phosphate equivalents). The removal of such a quantity of nutrients might be beneficial if the local marine environment is at risk of hypernutrification, but when no such problem is present, the potential for undesirable consequences of nutrient sequestration should be considered. The major contributor towards the impacts of mussels is the provision of infrastructure (between 25 % and 99.5 %, excluding eutrophication potential). Infrastructure is also responsible for the majority of contributions from mussel seed production. The provision of cotton mesh bags, which are used to aid attatchment of seed to drop-ropes in the grow-out phase, account for between 37% and 99 % of the contributions from the infrastructure from the grow-out phase. This result suggest that either the impacts of mussel production can be reduced by using an alternative material with lower environmental impact potentials, or the inventory data describing the producing of cottonmesh bags requires some improvement. The outcomes of the LCAs of the different IMTA scenarios, are interesting. The results show that choice of species, and the ratios of their combination as required for the different efficiencies of bioremediation, can have a significant effect upon the comparison between IMTA and monoculture.The study demonstrates a potential for environmental problem shifting as being a consequence of IMTA, especially when the functional unit is mass-adjusted economic value. As bioremediation efficiency increases, contributions towards eutrophication decrease. However, this reduction is achieved at the cost of increasing the contributions of IMTA towards those impact categories, such as ‘ozone layer depletion,’ for which it has a greater contribution than does monoculture. In general, it cannot be concluded from these results that open-water IMTA represents a more sustainable alternative to the monoculture production of Atlantic salmon. The sustainability of IMTA is shown to be dependent upon a variety of trade-offs, between individual environmental impacts, and between these impacts and the nutritional function that the system is capable of providing.

Full textAbstract:
The main parasite affecting the Scottish Atlantic salmon farming industry is Lepeophtheirus salmonis costing approximately £29 million annually through lost production and treatments. As such, the primary aim of this study was to investigate the infection pressure, fecundity and infection dynamics of L. salmonis in a west coast sea loch containing salmonid aquaculture. Atlantic salmon held in small sentinel cages were used to monitor sea lice infection pressure in Loch Shieldaig. Investigation of the factors affecting infection pressure within the loch found no evidence of a direct link between monthly gravid lice counts on local farmed salmon and lice burdens on sentinel cage fish. Copepodid L. salmonis were present throughout the year despite there being low numbers of wild salmonids in the system during much of the year and as such the source of this infection was unclear. In subsequent laboratory trials, L. salmonis from wild salmon were found to be more fecund than those from farmed salmon and similarly, fecundity and survival were also higher in summer compared to winter populations of L. salmonis. These findings raise the possibility that L. salmonis infecting wild salmonids may “seed” previously fallowed systems. Alternatively, trials with atypical hosts found that L. salmonis of farmed origin did re-infect Atlantic cod and produce viable egg strings which moulted through to the infective copepodid stage. Infection challenges demonstrated that L. salmonis copepodids were observed to settle on atypical hosts such as saithe and Atlantic cod in low numbers although failed to develop to the chalimus stages and complete its lifecycle. Challenges utilising the mobile pre-adult stage were similarily unsuccesful in allowing L. salmonis to moult to the adult stage on these atypical hosts. Previous work conducted on Pacific three-spined sticklebacks demonstrated the species could support large burdens. In infection trials with three-spined sticklebacks from Scotland’s west coast, settlement was found to be low, which suggests they play no role in the Scottish inshore infection dynamics of L. salmonis. These series of studies provide novel and timely data on the biology and infection dynamics of L. salmonis on typical and atypical hosts in Scottish marine aquaculture areas. The data will form part of the knowledge used to make informed pest management and policy decisions assisting the future development of the aquaculture industry in Scotland.
