Abstract:
Lift-nets is one of the important fisheries sectors that become the source of coastal comunity livelihood in Krueng Raya, Aceh Besar. The operation of the fishing gear is always supported by the fishing tools that can assist the operation process, as well as the lift-nets that exist in the Krueng Raya area. The main fishing tools on the lift-nets in Krueng Raya are lights, generator and roller. The lack of data and information on the characteristics of fishing equipment becomes an obstacle to improve the development of lift-nets. This study aims to identify fishing equipment used in lift-nets at Krueng Raya. The data were collected by interviewed and directed field observation. Descriptive analysis showed the fishing equipment used in lift-nets in Krueng Raya used neon and mercury lamps, the generator capacity is 15000 watts and roller made of bayur wood (Pterospermum javanicum). The updates of the fishing equipment used in lift-nets at Krueng Rayacan still be made. Kata kunci: Krueng Raya, Lift Net

Abstract:
The study aims to determine the technical characteristics of fishing gear used in the small-scale fishery in Marmara Ereglisi and to give the fishing potential of Marmara Ereglisi. The study was conducted during the 2022-2023 fishing season at the Marmara Ereglisi fishing shelter. Our results are based on the surveys conducted with 14 commercial fishermen and personal observations. Accordingly, 15 different set nets (9 gill nets and 6 trammel nets), five different fishing lines, and 1 type of beam trawl were identified. In the small-scale fishing activity in Marmara Ereglisi, 38 other fish species (13 target and 36 non-target) were caught. This study concludes that small-scale fishing in Marmara Ereglisi has significant potential in the fishing gear used and the species seen. The study is the first to focus on the technical specifications of fishing gear used in Marmara Ereglisi.

Abstract:
Abstract The Duano Tribe are fishermen that run fishing businesses traditionally. Generally, they use longlines and drift gill nets equipment for fishing. The purpose of this research is to analyze the income of fishermen that use longlines and drift gill nets based on the main catch of Belanak and Senangin fish and the contribution of fishing business income to the total fisherman income. The descriptive method that the author used to analyze where data were collected from 29 fishermen of Duano Tribe. This research was conducted in Tanjung Pasir village, Indragiri Hilir, Riau, in May 2021. The result shows that the average fishing income of Duano Tribe that use longlines is IDR.51,782,948.-year-1 and the average fishing income of Duano Tribe that uses drift gill nets is IDR.26,931,235.-year-1. The income of the Duano tribe using longlines is higher than drift gill nets, even with the same average duration of fishing. The contribution of income using longlines to the income of the Duano Tribe fishermen is 85 percent, and the contribution of income using drift gill nets to the income of the Duano Tribe fishermen is 78 percent. The income contribution using longline is higher than the income contribution using drift gill nets. Based on the contribution criteria, both income from fishing with drift gill nets and longlines provide a high contribution.

Abstract:
Plastic waste generation has become an important problem that critically affects marine and oceans environments. Fishing nets gear usually have a relatively short lifespan, and are abandoned, discarded and lost, what makes them one of the largest generators of ocean plastic waste. Recycled polyolefin resins from fishing nets (rFN), especially from polyethylene (PE), have poor properties due to the presence of contaminants and/or excessive degradation after its lifetime. These reasons limit the use of these recycled resins. This work aims to study the incorporation of recycled fishing nets PE-made to different grades of virgin PE, in order to evaluate the potential use of these rFN in the development of new products. The recovered fishing nets have been fully characterized to evaluate its properties after the collection and recycling process. Then, different PE virgin resins have been mechanically blended with the recovered fishing nets at different recycling contents to study its feasibility for fishing nets or packaging applications. Critical mechanical properties for these applications, as the elongation at break, impact strength or environmental stress cracking resistance have been deeply evaluated. Results show important limitations for the manufacture of fibers from recycled PE fishing nets due to the presence of inorganic particles from the marine environment, which restricts the use of rFN for its original application. However, it is proved that a proper selection of PE raw resins, to be used in the blending process, allows other possible applications, such as non-food contact bottles, which open up new ways for using the fishing nets recyclates, in line with the objectives pursued by the Circular Economy of Plastics.

Abstract:
Neuroendocrine tumors (NETs) are a class of rare and heterogeneous neoplasms that originate from the neuroendocrine system. In several cases, these neoplasms can release bioactive hormones leading to characteristic clinical syndromes and hormonal dysregulations with detrimental impact on the quality of life and survival of these patients. Only few animal models are currently available to investigate pathogenesis, progression and functional syndromes in NETs and to identify new therapeutic strategies. The tropical teleost zebrafish (Danio rerio) is a popular vertebrate model system that offers unique advantages for the study of several biological processes, ranging from embryonic development to human diseases such as cancer. In this review, we summarize recent advances on zebrafish models for NET preclinical research that take advantage of modern genetic and transplantable technologies. In the future, these tools may have a role in the treatment decision-making and tertiary prevention of NETs.

Full text
Abstract:
We propose a method to deal simultaneously with model uncertainty and correlated regressors in linear regression models by combining elastic net specifications with a spike and slab prior. The estimation method nests ridge regression and the LASSO estimator and thus allows for a more flexible modelling framework than existing model averaging procedures. In particular, the proposed technique has clear advantages when dealing with datasets of (potentially highly) correlated regressors, a pervasive characteristic of the model averaging datasets used hitherto in the econometric literature. We apply our method to the dataset of economic growth determinants by Sala-i-Martin et al. (Sala-i-Martin, X., Doppelhofer, G., and Miller, R. I. (2004). Determinants of Long-Term Growth: A Bayesian Averaging of Classical Estimates (BACE) Approach. American Economic Review, 94: 813-835) and show that our procedure has superior out-of-sample predictive abilities as compared to the standard Bayesian model averaging methods currently used in the literature.

Full text
Abstract:
This thesis develops statistical methodology for modelling the selectivity of fishing nets, using data from covered codend experiments of fishing trawls. First, the effects of subsampling an experimental catch instead of measuring the entire catch are investigated. Often the subsample is not taken at random. This leads to bias in the selectivity parameter estimates. Simulations show that the effects of non-random subsampling are minimised when equal proportions are sampled from the test and the control net. A model is developed for describing the selectivity of a net with a window panel inserted. This model quantifies the selectivity of both the codend and the window panel, which can then be combined. The model is used to investigate the selectivity of different window panels and their contribution to the combined selectivity. Traditionally, selectivity has been modelled as a fixed and random effects model, estimated in two stages. As an alternative, Markov chain Monte Carlo techniques are explored. A Bayesian selectivity model is formulated, and the effect of the prior distribution on the variance components is investigated. The posterior distribution is relatively insensitive to a prior distribution having variation of similar magnitude as the variation present in the data. For model selection, the p-value approach applied to the posterior marginal densities is more useful than the Bayes and pseudo-Bayes factors. The Bayesian selectivity model is extended to include variation between seasons and variation between trips. The new model is applied to a data set containing seasonal variation. Finally, a Bayeisan multi-species model is developed that accounts for dependencies between species. This gives more precise selectivity parameter estimates. It also reduces bias in the parameter estimates by accounting for mechanisms behind non-random missing data.

Abstract:
Approved for public release; distribution is unlimited
Somali piracy reached a record high level in 2008, with 111 of the 293 worldwide attacks occurring in the waters surrounding Somalia. The incidence of piracy in Somali waters almost doubled in 2009, and the Somali share of total piracy attacks worldwide increased from under 40% to over 50%. Often overlooked is the initial upsurge in piracy, following the Indian Ocean tsunami in December 2004, which contributed to a sharp increase in piracy in 2005 and again in 2008. This thesis addresses why this initial surge occurred when it did. This increase can be attributed to the transformation of the pirate business model from fishermen who started to defend themselves, to the organized crime that displaced them in 2004 due to the opportunistic behavior of warlords. A convergence of factors contributing to the conditions at the time of the tsunami had shortterm effects in 2005 that were enough to provide a boost to the already increasing business model of piracy.

Abstract:
This thesis presents a numerical model for the calculation of the flow field and resistance of a fishing net. This numerical method is based on the potential flow theory and an empirical formula to predict the force acting on a mesh of the netting. An experiment to determine the shape, flow field, and the resistance of a conical net has been carried out in the flume tank at the Marine Institute located at St. John's, Newfoundland, and the experimental results are presented as well. The net drag force obtained by this numerical procedure is compared with the flume tank experiments as well as with methods developed by other researchers. Although the result from the numerical model does not agree well with some methods developed by other researchers, it does have better agreement with the results obtained from the flume tank experiments. The flow field around the fishing net calculated by the numerical model at various incoming velocities is obtained.

The Amazon in general, in terms of human occupation, is known as a demographic void, but it is known today that this discourse does not proceed. There are historical records that prove that the Amazon was always occupied by people who lived in the region. The Amazonian floodplains were so populated that these peoples migrated to populate the rest of the South American continent, as Fausto states (2010, 31). "From their floodplains, as rich as they were fought by an ever-growing population, would have led to migratory waves that would populate the South America¨. In this imaginary context of "demographic", we are struck by the contemporary process of urbanization to which this biome belongs. In this process the Vilas in Alto Solimões / Amazonas, with a total population of more than 1.000 inhabitants. In this work we will deal with the Copatana Village, located in the Alto Solimões / Amazonas microregion belonging to the municipality of Jutaí. The region has agriculture as the main source of income, however, it was the fishing bias that best describes the relationship between the city and the village. In this sense, the main objective of this work was to understand, through commercial fishing networks, the role of Copatana Village in the structuring of the urban network of the Alto Solimões / Amazonas microregion. In order to achieve this objective, it was extremely important to implement monitoring. This was one of the options we thought and carried out as one of the ways of collecting primary data, in this case, fishing. Tracking was inspired in the works of VanVliet et al. (2015) and TavaresPinto (2015), both conducted their research on wild animal hunting networks on the Brazil- Peru-Colombia triple border. Due to the lack of specific secondary data for the site, the field work carried out in the town of Copatana was crucial for the research and understanding of the processes that occur. At the end of the research, it was concluded that the commercial fishing network and the urban network in Amazonas are totally interconnected from the town of Copatana, in the municipality of Jutaí, to cities like Tabatinga and Manaus or other cities outside the state and the country through commercial fishing networks.
A Amazônia de forma geral, em termos de ocupação humana, é conhecida como um vazio demográfico, mas sabe-se hoje que esse discurso não procede. Existem registros históricos que comprovam que a Amazônia sempre foi ocupada por povos que viviam na região. As várzeas amazônicas eram tão povoadas que estes povos migravam para povoar o resto do continente Sul- Americano, como afirma Fausto (2010, p. 31) "De sua várzea, tão rica quanto disputada por uma população sempre crescente, teriam partido levas migratórias que iriam povoar a América do Sul". Neste contexto imaginário de "vazio demográfico" nos chama a atenção o processo contemporâneo de urbanização a qual este bioma se insere. Neste processo ressaltam-se as Vilas no Alto Solimões/Amazonas com população total acima de mil habitantes. Neste trabalho trataremos sobre a Vila de Copatana, localizada na microrregião do Alto Solimões/Amazonas pertencente ao município de Jutaí. A região possui a agricultura como principal fonte de renda, contudo, foi pelo viés da pesca que melhor conseguimos descrever as relações existentes entre a cidade e a Vila. Neste sentido, o trabalho teve como principal objetivo compreender por meio das redes comerciais de pesca o papel da Vila de Copatana na estruturação da rede urbana da microrregião do Alto Solimões/Amazonas. Para alcançar tal objetivo, foi de suma importância a implantação de um monitoramento foi uma das opções que pensamos e realizamos como uma das formas de colher dados primários, neste caso, de pesca. O monitoramento foi inspirado nos trabalhos de Van-Vliet et al. (2015) e Tavares-Pinto (2015), ambos realizaram suas pesquisas sobre as redes de caça de animais selvagens na tríplice fronteira Brasil-Peru-Colômbia. Devido à quase inexistência de dados secundários específicos para o local os trabalhos de campo realizados na Vila de Copatana foram cruciais para a pesquisa e o entendimento dos processos que ocorrem. Ao final da pesquisa chegou-se à conclusão de que a rede comercial da pesca e o urbano no Amazonas está totalmente interligado desde a Vila de Copatana, no município de Jutaí, às cidades como Tabatinga e Manaus ou outras cidades fora do estado e do país por meio de diversas redes comerciais de pesca.

Humanity has been fishing for a long time, more specifically underice with nets, this could be a lot more efficient if it could beautomated in any stage of the procedure. The project aim is toconstruct an automated system for assisting in net fishing under ice.A navigation system using a GPS module, an IMU and radio transceiverwas designed, constructed and implemented on a car for testing. Theresult was a system that could navigate to either a predeterminedpoint or return to a point saved by the system. A "manual mode" wasalso implemented to be able to operate the system as a remotecontrolled car with a computer coupled to an Arduino with a radiotransceiver sending control signals to the prototype. The prototypeworked as intended, but would need further improvements to theautomated navigation system's precision to be ready for commercialuse. This should be the primary focus of any further development ofthis project.

Abstract:
The scene of a local motorcycle taxi driver hand-knitting a small fishing net at his stand next to a canal will never fade away from my childhood memory. It was the first time I saw the life behind the fishing net. Throughout my textile practice, I’ve reconsidered the fishing net with curiosity and nostalgia. Behind its mesh and diamond shaped structure, I see craftsmanship and the story of its creation. I would like to preserve and encourage these precious values in the net with my Master project Sitting with The Fisherman. The fishing net is reinterpreted to everyday life with a trace of stories within it. The net becomes a tool to gather people together like the fishing net does in the fisherman village. This project will be a pilot idea to others in different contexts, to preserve their precious traditional craftsmanship, to keep it alive by transforming the skill and technique to a new interpretation.

Impact investing is growing as a development approach to bring about positive social, environmental and economic impact for marginalized people in the developing world. But existing in a developed country like Canada, the Aboriginal communities are not getting enough attention due to lack of capacity, state dependency, state policies and negative perception among the stakeholders in the financial ecosystems. This thesis followed mixed methods participatory action research approach and had a deeper look on the present investment ecosystem and identified many barriers to investment for Aboriginal cooperative or social enterprise including negative stereotypes regarding Aboriginal communities impeding investing in cooperative or social enterprise. However, proper education, financial inclusion, awareness among stakeholders and engaging micro-investors in Aboriginal enterprises could improve the situation and develop opportunities for both the supply and demand side.

Abstract:
Purpose The purpose of this study is to explore how the use of clickbait marketing strategies by online news outlets affects consumer perceptions of online news content quality.   Design/methodology/approach A qualitative, deductive, exploratory and cross-sectional method, wherein data was collected through semi-structured interviews to understand consumer perceptions of how the use of clickbait strategies affects perceived online news content quality. The gathered data was then analyzed with the help of a directed content analysis supported by qualitative content analysis software Atlas.Ti. Findings This study found that the use of clickbait content strategies affected the perceived quality of online news content. Furthermore, it was found that there are two primary consumer groups, one of which seeks to avoid clickbait and one of which seems to engage with clickbait. Finally, several new variables were found for perceived news content quality that applied in the online space. Research limitations/implications The main implications of this research are that clickbait strategies should be utilized cautiously as they are often found misleading or displeasing, and may cause damage to the publisher. Furthermore, despite clickbait sometimes being entertaining, most clickbait was found to be highly context sensitive. Finally, a number of new variables were found that expanded previous understandings of perceived news quality. This study was limited by several factors - firstly, a lack of english as a first language which may have resulted in misunderstandings. Secondly, the articles utilized were found to have several shortcomings during the research procedure. Finally, due to the qualitative nature of this study, its findings are non-generalizable.

Abstract:
AbstractResearch on the use of recycled plastics in construction materials has increased over the last decade. The major trends and recycling applications for plastic waste in construction materials are reviewed in this chapter with a special focus on the use of discarded fishing nets as reinforcing material. The experimental part of this project included the characterization of discarded fishing nets of polyethylene with the aim of discovering new recycling alternatives for the use of fishing nets as reinforcement in different types of construction materials. The fishing net material was added either in the form of fibers or as pieces of net. The characterization of the polyethylene fibers showed that the material properties were in the same range as some commercially available fibers used in construction materials. The influence of the addition of fishing nets to construction materials was evaluated based on the mechanical performance and early-age shrinkage properties of cement-based mortars, gypsum, and earth-based adobe bricks. The results showed that the addition of fishing net fibers improved the post-crack performance of all types of tested construction materials, but the most prominent gain in mechanical properties was obtained for the earth-based adobe bricks. The addition of fibers was also found to mitigate shrinkage deformations and cracking of cement-based and earth-based materials.

Abstract:
AbstractFishing nets are mainly constituted of Polyethylene (PE), Polyamide, Polyethylene terephthalate (PET), Polypropylene (PP), and Nylon. While new, these plastics exhibit pristine mechanical performance but lose it as they age. But what about their metal adsorptive performance? Literature finds that plastics like PET and PVC accumulate Al, Cr, Mg, Fe, Co, Ni, Zn, Cd, and Pb, even when exposed to very low concentrations. This is mainly true for aged PVC (Kedzierski et al. Adsorption/desorption of Micropollutants. Mar Pollut Bull. 127:684–694, 2018). In this study, we look at the effect of age on the properties of fishing nets, including their capacity to adsorb metals. Because fishnets are in great part constituted by PE, we used standardized PE pellets as our reference. In calorimeter signaling, we observed that end-of-life fishing nets display a very different differential scanning calorimetry (DSC) pattern; both new and old fishing nets are very different from standardized PE polymer. Preliminary results show that Cr, Cu, Pb, and Se adsorption onto fishing nets occurs in the first 10 min to 6 h of exposure (24 h for Se). The maximum uptake was registered at 11 mg Cr kg‒1, 38 mg Cu kg‒1, 27 mg Pb kg‒1, and 15 mg Se kg‒1. All these concentrations refer to old end-of-life PE fishing nets, where new, unused PE fishing nets adsorb 2–20 times less (Old in this chapter refers to used fishing nets. The term is not attempting to attribute a particular life span/age to the nets). A comparison to different EU directives that regulate metal content in plastics for different end-uses shows that the old end-of-life PE fishing nets, after exposure to heavy metals, do not meet the regulations for hazardous waste. We believe that Greenlandic old waste fishing nets can be used to clean the wastewater, or metal-contaminated water, in Greenland and eventually, the rest of the world.

Abstract:
AbstractThere is growing concern regarding the extent and impact of marine litter waste. One particularly troublesome ocean waste fraction consists of abandoned, lost, or discarded fishing gear, including fishing nets. The relentless increase of marine litter is particularly pertinent to countries of Northern Europe and the Arctic region, which currently have limited business opportunities and associated supply chains capable of recycling or reusing this material. In this chapter, we outline the difficulties and opportunities in establishing a circular economy for fishing nets in Northern Europe and the Arctic, with a focus on experience and successful practices established through transnational and collaborative projects.

Abstract:
AbstractRivers and peat swamps provide fishing grounds that can support the people living in Rantau Baru. Survey activities were conducted to describe the capture fisheries business carried out by fishers. The survey results show that 109 of 623 residents work as fishers, including women. Small-scale traditional fishing gear, such as traps, gillnets, mini long lines, set nets, pole and line, and cash nets are used, but traps are the dominant gear. Transportation to catch fish relies on boats, outboard motorboats, and fishing vessels. The outboard motorboat is widely used by fishers because of its small size and ability to navigate shallow and narrow waters. At least 44 species of fish from 10 families are caught and sold by fishers. Catches fluctuate according to the seasons, with increases during the flood season and decreases during the dry season. The fishing grounds also have potential for recreational fishing activities, as fishers earned US$37,242.67 from boat rental services for fishing-related tourism activities in 2019. This chapter provides an overview of the fishing activities and the economic value generated from fishing activities in the rivers and peat swamps of Rantau Baru.

Abstract:
AbstractBottom trawling developed from the practice of fishing with a net or long lines, but that older style was able to be more controlled and discriminate in its catch. With bottom trawling, nets are weighted to keep them low along the seafloor and a large beam on deck spreads nets wide to increase catch. Marine biologists and environmentalists have been concerned about trawling since it began. As far back as 1376, the English parliament highlighted the destructive nature of the practice to fish populations and habitats, noting that it ‘runs so heavily and hardly over the ground when fishing that it destroys the flowers of the land’ and takes so many fish ‘to the great damage of the commons and the destruction of the fisheries’ (Petition by the Commons to King Edward III, 1376 seen in Bolster, 2012). This first known mention of trawling calls for the removal of the practice and yet the activity endures. Trawling in Europe continued sporadically through the medieval and early modern periods using mainly the beam trawl method until the early nineteenth century when the industrial revolution pushed the technology further.

Abstract:
AbstractRecycling plastic materials including fishing nets, ropes, and components (FNRCs) through the business models of SMEs and microenterprises can ensure both economic and environmental benefits. The aim of this chapter is to explore how a circular business model for SMEs in the fishing gear industry can be realised and to provide increased understanding of the circular business model processes. The study examined the development of circular business models and practices of circularity by companies in the fishing gear industry. We applied a qualitative research design and developed frameworks to evaluate the practice of circularity. The qualitative analysis and findings of the cases provided unique insights on the level of circularity of SMEs within the marine plastic recycling value chain in the north-western part of Norway. The main outcome of this research was the proposed framework for a circular business model for the fishing gear industry.

Abstract:
Modern nets consist of meshes made of threads or twines with spirals or helical strakes. Fluid-structure interactions have been investigated in Rostock for a long time applying different theoretical models. Because of great net flexibility there is a need of calculation methods which consider the main physical qualities. This is done by the approximation of wake of threads by results from circular cylinders and influence of circulation, which is known from measurements of transverse force. Results of measurements with two models with and without spirals are given for comparison.

Abstract:
A two-dimensional numerical wave flume is established based on the finite-volume method. The movement border method is adopted as a wave generator at one end of the flume. The volume of fluid (VOF) method is used to track the wave surface. In the numerical simulation, the plane net is simplified as porous-media model. The coefficients of the porous media are determined by the least squares method. In this way, the porous-media model will has the same pressure drop with the fishing net. To validate the numerical model, the numerical results are compared with the data obtained from corresponding physical model tests. It is found that the numerical results are in good agreement with the corresponding experimental data. Using the proposed numerical model, wave propagation through a plane net with different net solidities, different attack angles as well as two nets with different spacing distances are investigated. The impacts of the wave height and wavelength on the wave propagation through the plane net are also discussed.

Abstract:
Coastal fish monitoring in the autumn has been conducted in Kvädöfjärden using the gear net series since 1989. The fishing methodology was revised in 2018 and resulted in only one night of fishing per station in contrast to six consecutive nights. Only the first night of fishing over all years has hence been included in the analysis in this report. A survey with Nordic coastal multimesh gillnets was performed for the first time in autumn the same year as the revision and has been executed annually since then. The methodologies are not fully comparable, and has thus been analysed separately in this report. The fish community is described using a set of indicators. Out of the environmental factors measured during monitoring, the water temperature has fluctuated over the years but without any directional trend. There is a decreasing trend in secchi depth in the short time series using Nordic coastal multimesh gillnets but no such trend is seen in the longer time series using the net series. In total, 20 species was caught in the survey using net series and 19 species in the Nordic coastal multimesh gillnet survey. Some species are caught using both gear types but some are unique to the respective method. The results show that there are no trends over time in the coastal fish community regarding the indicators total catch, abundance of mesopredators, abundance of piscivores, abundance of large fish, the number of species caught, diversity index and the mean trophic level of the monitoring catch. Some species in the catches (cod, whiting and burbot) are classified as vulnerable (VU) in the Swedish Red List of species 2020 by the Swedish Species Information Centre at the Swedish University of Agriculture. Vimba bream that also occurs in the catches is classified as near threatened (NT). The most common species in the survey with net series were roach and perch, but in the past few years, ruffe made up a substantial proportion of the catches. Herring is dominating the catch in the surveys with Nordic coastal multimesh gillnets, but roach and perch also constitutes a large proportion of the total catch. European smelt is the only species with an increasing trend over time while perch, white bream, pike and European flounder all have decreasing trends in the net series survey. In the survey with Nordic coastal multimesh gillnets, herring and sprat showed increasing trends over time. The catch of large fish over 30 cm was in general small and mostly comprised of whitefish in both surveys. In the net series survey, roach was also a substantial part of the large fish. European flounder had condition index over the threshold value for good condition in Kvädöfjärden and no trend over time was observed for the index. In conclusion, it can be noted that the coastal fish community in Kvädöfjärden has been relatively stable during the assessed time series, with a few exceptions. In the long time series, European smelt has increased over time and perch, white bream, pike, and European flounder have decreased over time. In the survey with the gear Nordic coastal multimesh gillnets with a considerably shorter time series, sprat and herring showed increasing trends. It can also be noted that whilst there are similarities in catches and indicators between the two fishing gears, the differences in the methodologies is also a factor that most likely can explain a large part of the dissimilarities in results between the gears.

van Gemert, Rob, Per Holliland, Konrad Karlsson, Niklas Sjöberg, and Torbjörn Säterberg. Assessment of the eel stock in Sweden, spring 2024 : fifth post-evaluation of the Swedish eel management. Department of Aquatic Resources, Swedish University of Agricultural Sciences, 2024. http://dx.doi.org/10.54612/a.4iseib7eup.

Full text
Abstract:
For decades, the population of the European eel has been in severe decline. In 2007, the European Union decided on a Regulation establishing measures for the recovery of the stock, which obliged Member States to implement a national Eel Management Plan by 2009. Sweden submitted its plan in 2008. According to the Regulation, Member States shall report regularly to the EU-Commission, on the implementation of their Eel Management Plans and the progress achieved in protection and restoration. The current report provides an assessment of the eel stock in Sweden as of spring 2024, intending to feed into the national reporting to the EU in August this year. This report updates and extends previous evaluation reports by Dekker (2012, 2015) and Dekker et al. (2018, 2021). In this report, the impacts on the stock - of fishing, restocking and mortality related to hydropower generation - are assessed. Other anthropogenic impacts (climate change, pollution, increased impacts of predators, spread of parasites, disruption of migration due to disorientation after transport, and so forth) probably have an impact on the stock too, but these factors are hardly quantifiable, and no management targets have been set. For that reason, and because most factors were not included in the EU Eel Regulation, these other factors are not included in this report. Our focus is on the quantification of silver eel biomass escaping from continental waters towards the ocean (current, current potential and pristine) and mortality risks endured by those eels during their whole lifetime. The assessment is broken down on a geographical basis, with different impacts dominating in different areas (west coast, inland waters, Baltic coast). In the last decade, a break in the downward trend in glass eel recruitment has been observed, with recruitment no longer declining consistently. Whether that relates to recent protective actions, or is due to other factors, is yet unclear. Nevertheless, recruitment levels remain at historically low levels. This report contributes to the required international assessment, but does not discuss the causing factors behind the recent recruitment trend and the overall status of the stock across Europe. For the different assessment areas, results summarise as follows: On the west coast, a commercial fyke net fishery on yellow eel was exploiting the stock, until this fishery was completely closed in spring 2012. A fishery-based assessment no longer being achievable, we present trends from research surveys (fyke nets). Insufficient information is currently available to assess the recovery of the stock in absolute terms. Obviously, current fishing mortality is zero (disregarding the currently unquantifiable effect of illegal fishing), but none of the other requested stock indicators (current, current potential and pristine biomass) can be presented. The formerly exploited size-classes of the stock show a recovery in abundance after the closure of the commercial fishery, and the smaller size classes show a break in their decline in line with the recent global trend of glass eel recruitment. In order to support the recovery of the stock, or to compensate for anthropogenic mortality in inland waters, young eel has been restocked on the Swedish west coast since 2010. Noting the quantity of restocking involved, the expected effect (ca. 50 t silver eel) is relatively small, and hard to verify – in comparison to the potential natural stock on the west coast (an order of 1000 t). However, for the currently depleted stock, the contribution will likely constitute a larger share of silver eel escapement. For inland waters, this report updates the 2021 assessment, with substantial changes in methodology being the use of a new natural recruitment model, and the full separation of Trap & Transport catches from the fisheries statistics. The assessment for the inland waters relies on a reconstruction of the stock from information on the youngest eels in our waters (natural recruits, assisted migration, restocking). Based on 78 years of data on natural recruitment into 22 rivers, a statistical model is applied which relates the number of immigrating young eel caught in traps to the location and size of each river, the distance from the trap to the river mouth, and the year in which those eels recruited to continental waters as a glass eel (year class). The further into the Baltic, the larger and less numerous recruits generally are. Distance upstream comes with less numerous recruits. Using the results from the above recruitment analysis, in combination with historical data on assisted migration (young eels transported upstream within a drainage area, across barriers) and restocking (young eels imported into a river system), we have a complete overview of how many young eels recruited to Swedish inland waters. From this, the production of fully grown silver eel is estimated for every lake and year separately, based on best estimates of growth and natural mortality rates. Subtracting the catch made by the fishery (as recorded) and down-sizing for the mortality incurred when passing hydropower stations (percentwise, as recorded or using a default percentage), an estimate of the biomass of silver eel escaping from each river towards the sea is derived. Results indicate, that since 1960, the production of silver eel in inland waters has declined from over 700 to below 300 tonnes per year (t/yr). The production of naturally recruited eels is still falling; following the increase in restocking since 2010, an increase in restocking-based production is expected to be starting right around now. Gradually, restocking has replaced natural recruitment (assisted and fully natural), now making up over 90 % of the inland stock. Fisheries have taken 20-30 % of the silver eel (since the mid-1980s), while the impact of hydropower has ranged from 25 % to 60 %, depending on the year. Escapement is estimated to have varied from 72 t in the late 1990s, to 175 t in the early 2000s. The biomass of current escapement (including eels of restocked origin) is approximately 15 % of the pristine level (incl. restocked), or almost 30 % of the current potential biomass (incl. restocked). This is below the 40 % biomass limit of the Eel Regulation, and anthropogenic mortality (70 % over the entire life span in continental waters) exceeds the limit implied in the Eel Regulation (60 % mortality, the complement of 40 % survival). Mortality being that high, Swedish inland waters currently do not contribute to the recovery of the stock. The temporal variation (in production, impacts and escapement) is partly the consequence of a differential spatial distribution of the restocking of eel over the years. The original natural (not assisted) recruits were far less impacted by hydropower, since they could not climb the hydropower dams when immigrating. Since 2010, inland restocking is increasingly concentrated to drainage areas falling to the Kattegat-Skagerrak, also including obstructed lakes (primarily Lake Vänern, and many smaller ones). Even though Trap & Transport of silver eel - from above barriers towards the sea - has contributed to reducing the hydropower impact, hydropower mortality remains the largest estimated contributor to silver eel mortality in inland waters. Without restocking, the biomass affected by fishery and/or hydropower would be only 5-10 % of the currently impacted biomass, but the stock abundance would reduce from 15 % to less than 3 % of the pristine biomass. In summary: the inland eel stock biomass is below the minimum target, anthropogenic impacts exceed the minimum limit that would allow recovery, and those impacts have been increasing. It is therefore recommended to reconsider the current action plans on inland waters, taking into account the results of the current, comprehensive assessment. For the Baltic coast, the 2021 assessment has been updated without major changes in methodology. Results indicate that the impact of the fishery continues to decline over the decades. The current impact of the Swedish silver eel fishery on the escapement of silver eel along the Baltic Sea coast is estimated at 0.3 %. However, this fishery is just one of the anthropogenic impacts (in other areas/countries) affecting the eel stock in the Baltic, including all types of impacts, on all life stages and all habitats anywhere in the Baltic. Integration with the assessments in other countries has not been achieved. Current estimates of the abundance of silver eel (biomass) indicates an order of several thousand tonnes, but those estimates are extremely uncertain, due to the low impact of the fishery (near-zero statistics). Moreover, these do not take into account the origin of those silver eels, from other countries. An integrated assessment for the whole Baltic will be required to ground-truth these estimates. This would also bring the eel assessments in line with the policy to regionalise stock assessments for other (commercial) fish species (see https://ec.europa.eu/oceans-and-fisheries/fisheries/rules/multiannual-plans_en). It is recommended to develop an integrated assessment for the entire Baltic Sea eel stock, and to coordinate protective measures with other range states.
