Abstract:
Eight species of spiny lobster (six littoral and two deep-sea) and two species of slipper lobster constitute the lobster fishery of India. Lobster landings fluctuate around 2000–3000 t annually. High export demand for Indian spiny lobsters has resulted in regular and organized exploitation, both inshore and offshore. Almost the entire quantity of lobsters landed in India is exported in frozen, cooked or live form. Export of live lobsters, which realize the maximum unit price, has increased from 22 t in 1994 to 97 t in 1996. Live transport of spiny lobsters has advanced from just keeping them alive for a few hours in moist intertidal beach sand to the most sophisticated packing in insulated boxes. The process involves holding the lobsters at the landing centre and at the city of export. The entire exercise lasts about seven days, during which period the lobsters are packed twice, each time keeping them out of water for not less than 20 h. In the holding centres, the lobsters are often kept at high densities, with the resulting build-up of nitrogenous wastes and depletion of dissolved oxygen leading to mortalities. Average mortality is up to 6.5% during live transport.

Abstract:
Ornate spiny lobster (Panulirus ornatus) in Sebatik Island is a commercial fisheries commodity that has the highest price if we compare it with another lobster caught by the fisherman in Sebatik Island Waters. That causes the effort to catch this lobster to increase continuously. The availability of biological aspects data of ornate spiny lobster is needed as a basis for sustainable lobster resource management in Sebatik Island. This research aims to analyze the biological performance of ornate spiny lobster in Sebatik Waters, coverage from study carapace length-frequency distribution and carapace length-weight correlation of ornate spiny lobster. This research is expected to provide benefits as basic information in lobster management. Information related to the biological condition of lobsters can be used as a consideration in strategies for the utilization and management of lobster resources. Measurement of carapace length, weight, and sex of ornate spiny lobster was carried out from April to August 2016 at lobster landing base in Sebatik Island, North Borneo, Indonesia. The results showed that the sex ratio shows an unstable ratio. The distribution catch size of ornate spiny lobsters ranged from 64.5–114.5 mmCL. The growth pattern of female and male ornate spiny lobsters was negative allometric with r and R2 values of both female and male >0.95. Carapace length at first ornate spiny lobster catch was 71.28 mmCL.

Abstract:
This study aimed to know the effect of different feedings on growth performance, physiological responses, and behavioral changes of juvenile spiny lobsters. The experimental method used a completely randomized design with three treatments and four replications. There were three different feeds used as treatment, namely: flesh mussel (K), commercial fish feed (I), and commercial shrimp feed (U). Feed is given as much as 30% of body weight, five times per day at 6:30 am, 12:00 pm, 4:00 pm, 9:00 pm, and 2:00 am. The results showed that the commercial feeding of fish (I) significantly (P<0.05) increased the survival rate and biomass of spiny lobster for 54.17% and 141.7 g, respectively. While fresh mussel give better growth and stress response, but had the lowest survival rate. The results of the physiological response test of lobster were more effective in suppressing lobster stress levels than other treatments (P<0.05). The behavior of juvenile spiny lobsters showed a very striking color difference and reflex impairment scores, which indicated that the vitality of the treated juveniles (I) was better than the vitality of the treatments (K) and treatment (U). This study shows that commercial fish feed (I) is recommended for maintaining spiny lobsters in the juvenile phase, although it needs further maintenance by using an appropriate feed formulation to improve the growth performance of spiny lobsters.

Abstract:
The continental shelf of Brazil is home to a wide range of lobster species, with varying body size, color, habitat preference, and geographic and bathymetric distribution. Spiny lobsters (Panulirus) and slipper lobsters (Scyllaridae) are exploited for export and for the domestic market. Deep sea lobsters (Nephropidae and Polychelidae) have no commercial potential, and little is known about their biology. In this review, we identified 24 lobster species from benthic ecosystems off Brazil (Palinuridae 25%, Scyllaridae 29%, Nephropidae 25%, Polychelidae 17%, Enoplometopidae 4%). We designed a simplified theoretical scheme to understand the role of lobsters in the ecosystem, based on available evidence of distribution, biodiversity, life cycle, connectivity, and abundance. Finally, we propose a theoretical scheme of trophic top-down control, with interactions between a large decapod (spiny lobster), a demersal predator (red snapper), an apex predator (small tuna), benthic invertebrates and fishing exploitation.

Abstract:
A complex nervous system enables spiny lobsters to have a rich behavioural repertoire. The present paper discusses the ways in which the sensory systems of the Caribbean spiny lobster, Panulirus argus, particularly its chemosensory systems, are involved in feeding behaviour. It addresses the neural mechanisms of three aspects of their food-finding ability: detection, identification, and discrimination of natural food odours; the effect of learning on responses to food odours; the mechanisms by which spiny lobsters orient to odours from a distance under natural flow conditions. It demonstrates that the olfactory organ of spiny lobsters might use acrossneuron response patterns in discriminating odour quality; that the hedonic value of food can be modified by experience, including associative and nonassociative conditioning; that spiny lobsters can readily orient to distant odour sources; and that both chemo- and mechanosensory antennular input are important in this behaviour. Either aesthetasc or nonaesthetasc chemosensory pathways can be used in identifying odour quality, mediating learned behaviours, and permitting orientation to the source of distant odours. Studying the neuroethology of feeding behaviour helps us understand how spiny lobsters are adapted to living in complex and variable environments.

Abstract:
Using diver surveys, we compared the size structure, fecundity, and reproductive season of spiny lobsters (Panulirus argus) in the Dry Tortugas National Park lobster sanctuary with those of spiny lobsters in the south Florida fishery. The number of lobsters of both sexes larger than the legal size limit declined sharply in the fishery but not in the sanctuary. Clutch sizes were larger in the Dry Tortugas sanctuary, averaging 0.8 million, than in the fishery, averaging 0.3 million. The reproductive season was shorter and more intense in the sanctuary than in the fishery. In addition, lobsters in the sanctuary begin producing eggs at a larger size and produce more eggs per gram of body mass than lobsters in the fishery. Peak egg production occurs earlier in larger lobsters than in small ones. Establishing a fundamental reason for the differences between lobster reproduction in the sanctuary and that in the fishery is not possible until the chronological age of lobsters can be determined, but one hypothesis consistent with these differences is that, if lobsters reproduce at a certain chronological age, then sublethal fishery practices may account for slower growth for some lobsters resulting in some smaller but older reproductively active lobsters.

Abstract:
Abstract A specific study has been carried out for the first time to investigate the homing capability and daily home range of the spiny lobster Palinurus elephas by means of ultrasonic telemetry. Nine lobsters collected in the Capo Gallo — Isola delle Femmine marine protected area (northwestern Sicily, central Mediterranean) were tagged with miniaturized transmitters and released at a single site inside the protected area. The lobsters were monitored with the purpose of calculating their horizontal and vertical positions, analysing their movement patterns to assess their homing capability, and calculating their daily home range. Five lobsters moved back close to the capture sites within the first 20 hours after release (‘homed’). The remaining four lobsters ‘relocated’ to a different refuge. Homed lobsters had a larger home range than relocated lobsters. This study provides the first description of a homing pattern with high spatial resolution in the wild European spiny lobster as inferred by ultrasonic telemetry.

Abstract:
Milky hemolymph disease of spiny lobster (MHD-SL) is categorized as the most destructive disease in farming spiny lobster. Therefore, it is required to investigate the routes of milky disease infection in spiny lobster as a basic knowledge in order to prevent milky disease transmission. The aim of the present study was to perform an experimental infection of milky disease in spiny lobster Panulirus homarus. Experimental infection of milky disease was carried out by several modes of infection which were injection, immersion and per os exposure. Injection of each 0.2 mL undiluted and diluted hemolymph from the diseased lobster resulted in a cumulative mortality of 100% at 15 days post-infection (dpi), and 75% at 16 dpi, respectively. Experimental infection through water immersion caused in a cumulative mortality of 50% at 7 dpi. In contrast, no mortality was observed in per os exposure as well as in control groups. Results of this experimental study provided evidence for horizontal transmission of MHD-SL among P. homarus. Histopathological analysis exhibited that there were masses of Rickettsia-like bacteria (RLB) in the connective tissues of the gill, hepatopancreas, gonad, midgut, and muscle tissues of the affected lobsters. Mass of RLB was not only found in the moribund lobsters but also in the surviving lobsters with milky hemolymph appearance.

Abstract:
Spiny lobster nursery is done to produce more adaptive and uniform juvenile lobsters quality. Shelters used in spiny lobster nursery served to reduce physical contact among lobsters in the rearing tank. The purpose of this study was to analyze the effect of different shelter types on physiological response and growth of spiny lobster (Panulirus homarus) juvenile rearing in recirculating aquaculture systems. Lobsters with an average weight of 50.07 ± 2.89 g were reared for 60 days. They were fed once a day with trash fish. The daily feeding rate was 3-4% of total weight. This study used four types of shelter as treatments with two replications. PVC pipe shelter as control (K), individual shelter square shaped (IS ■), individual shelter triangle shaped (IS ▲), and individual shelter tube shaped (IS ●). The weight and length of the lobster carapace improved with the duration of the research in all treatments. Throughout the trial, glucose levels in controls were generally greater than those in specific shelf treatments. The reaction of lobster hemolymph total protein to different shelters is highly variable. Overall, the usage of individual shelters had a considerable positive influence on grown lobsters in this study. This is because individual shelter eliminates contact between lobsters, eliminating the possibility of cannibalism in the cultivation container. This study concludes that IS ■ used in rearing Panulirus homarus showed a lower stress response than the other treatments in terms of glucose and total protein lobster hemolymph during the study. IS ■ is the best because it reduced stress levels and yielded better total biomass among the other treatments.

Abstract:
Abstract The two spiny lobster fisheries targeting Panulirus argus (Latreille, 1804) and Panulirus laevicauda (Latreille, 1817) have made an important marine resource in Northeast Brazil since 1955. The Von Bertalanffy age and growth parameters of the spiny lobster started being studied in 1960 and the last assessment was performed over 20 years ago. The objective of this review is to analyse the type of input data and the methods historically used to assess age and growth of the spiny lobster stock in Northeast Brazil. Our study reviews and updates the research on the subject and proposes relative values for the Von Bertalanffy growth parameters for P. argus and P. laevicauda as provisional reference. We recommend further age and growth research on spiny lobsters to create a new and updated growth function for commercial lobsters in Northeast Brazil.

Abstract:
[Truncated abstract] In this thesis I investigated the ingestive and digestive morphology and digestive physiology during development of phyllosomata of the ornate spiny lobster, Panulirus ornatus. This knowledge was applied to develop a suitable formulated diet to be fed in combination with Artemia or used as a supplement to reduce production costs. The major impediment to closure of the life cycle of spiny lobsters has been an inadequate dietary regime, stemming from a lack of information on their feeding biology and ingestive and digestive capabilities. Of all spiny lobster species, P. ornatus is the best candidate for aquaculture in Australia having the shortest larval development phase (46 months) and fast growth rate, attaining 1 kg within 2 years of hatch. Currently, Artemia and fresh feeds such as mussel are used routinely as hatchery feeds. However, the development of a formulated diet that is palatable and delivers the correct balance of nutrients is seen as a highly attractive and cost effective alternative. An appropriate formulated diet for aquaculture of phyllosomata of spiny lobsters can be developed more effectively when the ingestive and digestive morphology, physiology and feeding behaviour are fully understood. ... Partial replacement trials revealed that P. ornatus phyllosoma are stimulated to feed by visual cues. Furthermore, 75% of the entire Artemia ration can be replaced with a formulated diet without having any adverse effects on survival and growth of early-stage phyllosomata. Weaning P. ornatus phyllosomata onto 100% formulated diet during stages II-III resulted in reduced survival but demonstrated that diets containing 44-50% crude protein with a diverse range of marine protein sources provides optimum survival and growth. This thesis has identified both physical and nutritional components that will contribute to the successful development of formulated diets for aquaculture of this species. Ultimately, although formulated diets are ingested and provide more than adequate survival when fed in combination with Artemia during early ontogeny, greater success and the possibility of totally replacing Artemia may occur after day 32 (stage IV) due to an increased efficiency to capture and manipulate larger sized particles externally and a greater capacity to triturate prey and sort and filter particles internally. Furthermore, a general increase in specific activity of digestive enzymes at stage IV suggests the possibility of a greater capacity to digest and assimilate nutrients.

Abstract:
This study is aimed to provide an understanding of the spiny lobster fishery of the south coast of Sri Lanka. Most of the spiny lobster fisheries of the world are subjected to heavy exploitation due to the increasing demand. The use of hazardous fishing methods however is known to cause serious problems in the developing countries, including Sri Lanka where considerable percentage of berried females and under sized lobsters are caught each year. The fishery for spiny lobster in the coastal waters of the south coast is carried out by non-mechanized out-rigger small canoes with trammel nets, bottom set gill nets and lobster rings. Around 200mt of lobsters is caught each year in the study area by a fishing fleet of 315 crafts. Around 80% of the lobster production consisted of Panulirus homarus. Lobsters were found to occur all year round, but the fishery is restricted to the non-monsoon period (August-March) due to operational difficulties. The analysis of catch and effort statistics indicated a maximum sustainable yield of 190-200 mt and an optimal daily effort of 300 crafts. The length-based analysis indicated that the resource is over exploited and a reduction in effort by about 20.5% is necessary to put the fishery back to an equilibrium level. Experimental fishing tests revealed that the lobster rings cause the least damage to the population, while the trammel net was the most harmful by including 77% of sub-legal lobsters in catches. This study indicated the possibility of having two spawning and recruitment pulses separated by an interval of 4-5 months. Fecundity estimates ranged between 116,000 - 601,000. Nearly two-third of the total egg production was contributed by lobsters of 60-79mm carapace length range. The fishery is reproductively supported by 3-4 year lobsters. This resource in the study area appears to be overfished with respect to its reproductive potential. The use of trammel nets and free access to the fishery are the two main points which should be carefully controlled. The fishery should be managed by using less harmful fishing gear (eg. lobster rings) and by introducing a proper licensing system to control fishermen entering into the fishery.

Abstract:
Chemical senses play a critical role in predator-prey and social interactions of many animals. Predators often evoke adaptive escape responses by prey, one of which is the release of chemicals that induce adaptive avoidance behaviors from both predators and conspecifics. I explore the use of chemicals in predator-prey and social interactions, using a crustacean model system, the spiny lobster. As predators, spiny lobsters are opportunistic, polyphagous feeders, and they rely heavily on their chemical senses during feeding. Some of their potential prey deter attacks through chemical defenses that act through the spiny lobsters’ chemical senses. An example of this is sea hares, Aplysia californica, which secrete an ink when vigorously attacked by sympatric spiny lobsters, Panulirus interruptus. I show that that this ink defends sea hares from spiny lobsters through several mechanisms that include phagomimicry, sensory disruption, and deterrence, and that the ink’s efficacy is enhanced by its naturally high acidity. As prey, spiny lobsters rely heavily on their chemical senses to assess risk from predators. One way to assess risk of predation is through ‘alarm cues’, which are injury-related chemicals. I show that injured Caribbean spiny lobsters, Panulirus argus, release alarm cues in their hemolymph, and that nearby conspecifics detect these cues using olfaction. Hemolymph from conspecifics induces primarily alarm behavior in the form of retreat, sheltering, and suppression of appetitive responses. In contrast, hemolymph from heterospecifics, depending on phylogenetic relatedness, induces either mixed alarm and appetitive behaviors or primarily appetitive behaviors. Spiny lobsters also use chemical cues to assess risk during social interactions with conspecific. I show that spiny lobsters use urine-borne chemical signals and agonistic behaviors to communicate social status and that these chemical signals are detected exclusively by the olfactory pathway. Dominant animals increase urine release during social interactions, whereas subordinates do not. Experimental prevention of urine release during interactions causes an increase in agonism, but this increase is abolished when urine of dominants is reintroduced. My findings lay the foundation for neuroethological studies of risk-assessment systems mediated by intraspecific chemical cues.

Abstract:
Includes bibliographical references.
A dispute arose in the Luderitz rock-lobster, Jasus lalandii, fishery as to whether declines in CPUE were due to changes in rock-lobster migration patterns or a reduction in fishable biomass. Rock-lobster migrations were studied at two sites by estimating in situ density in the 10-12m and 15-20m depth zones. Water temperature and dissolved oxygen concentration profiles were obtained at several sites at approximately monthly intervals. Observations over a period of six years indicated that rock-lobster underwent seasonal in- offshore migrations and that marked interannual variation in those migration patterns did, indeed, occur. The movements and their interannual variation were directly related to the inshore presence of water with very low dissolved oxygen concentrations. CPUE was closely related to the density of legal sized rock-lobster on the fishing grounds (observed by SCUBA diving) and hence it is feasible that at least a part of the decline in CPUE at Luderitz was due to an alteration in the "normal" pattern of in-offshore migration. The hypothesis that environmental change caused the major decline in rock-lobster catches at Luderitz was examined by time series analysis of 21 years of CPUE, wind, SST and sea-level data. Luderitz rocklobster CPUE was found to be negatively correlated with the southerly component of summer wind stress at Diaz Point six years previously. On this basis it was hypothesised that variable settlement of puerulus larvae is an important factor driving changes in recruitment to the fishable population. The mechanism may be increased mortality of larvae as they attempt to cross the continental shelf (due to greater northward and offshore drift during periods of strong southerly wind). The dramatic interannual changes in rock-lobster density provided an opportunity to carry out a "natural" experiment on the interaction between rock-lobsters and the associated benthic species assemblage. It was found that, although there were changes in the benthos (notably an increase and subsequent decline in whelk density), these were unrelated to variation in rock-lobster density. In addition, no relationship between per capita food availability and rock-lobster growth on four grounds, was apparent. As regards temporal changes in food supply and subsequent effects on rock-lobster growth rates; there was no temporal reduction in food supply at the main study site which could be related to the reduction in CPUE since 1988.

Abstract:
[Truncated abstract] Removal of consumers through fishing has been shown to influence ecosystem structure and function by changing the biomass and composition of organisms occupying lower trophic levels. The western rock lobster (Panurilus cygnus), an abundant consumer along the temperate west coast of Australia, forms the basis of Australia's largest single species fishery, with catches frequently exceeding 11000 tonnes annually. Despite their high abundance and commercial importance, the diet and trophic role of adult lobster populations in deep-coastal-ecosystems (35-60 m) remains unknown. An understanding of the diet and trophic role of lobsters in these ecosystems is a key component of the assessment of ecosystem effects of the western rock lobster fishery. This study uses gut content and stable isotope analyses to determine the diet and trophic role of lobsters in deep-coastal ecosystems. Dietary analysis indicated adult lobsters in deep-coastal ecosystems were primarily carnivorous with diet reflecting food available on the benthos. Gut content analyses indicate crabs (62 %) and amphipods/isopods (~10 %) are the most important lobster dietary sources. Stable isotope analysis indicates natural diet of lobsters in deep coastal ecosystems is dominated by amphipods/isopods (contributing up to ~50 %) and crabs (to ~75 %), with bivalves/gastropods, red algae and sponges of lesser importance (<10 % of diet each). Diet of lobsters in deep-coastal ecosystems differed from that reported for lobsters inhabiting shallow water ecosystems in this region, reflecting differences in food availability and food choice between these ecosystems. Bait from the fishery was also determined (by stable isotope analyses) to be a significant dietary component of lobsters in deep-coastal ecosystems, contributing between 10 and 80 % of lobster food requirements at some study locations. '...' Given observed effects of organic matter addition in trawl fisheries, and also associated with aquaculture, bait addition is likely to have implications for processes occurring within deep-coastal ecosystems in this region, particularly given its oligotrophic status, most likely by increasing the food available to scavenging species. Removal of lobsters from deep-coastal ecosystems may affect the composition and abundance of lobster prey communities through a reduction in predation pressure. Such effects have been demonstrated for other spiny lobster species. These effects are typically most observable amongst common prey taxa which in other studies have been commonly herbivores. In deep-coastal ecosystems, crabs and amphipods/isopods are the most common prey taxa and most likely to be effected. The ecosystem-impacts of top-down control of non-herbivorous prey species is unknown and constrains the inferences possible from this study. However, the establishment of 'no-take' areas in deep-coastal ecosystems would allow the ecosystem effects of lobster removal to be further assessed in these deep-coastal ecosystems. While data from the current study did not allow the ecosystem effects of lobster removal to be properly assessed, this study provided information regarding the ecology of western rock lobsters in previously unstudied ecosystems.

ENGLISH ABSTRACT: This study investigated the evolution of the genus Palinurus at the higher and lower taxonomic levels. The population genetics of the spiny lobster, Palinurus delagoae, was investigated by making use of a portion of the mitochondrial DNA (mtDNA) control region (547 base pairs) that was sequenced for 285 lobsters from the southeastern coast of Africa (six sites) and 49 lobsters from Walters Shoals (one site), a submerged seamount on the Madagascar Ridge. Lobsters from these two areas shared no haplotypes and differed by at least 27 mutational steps. An analysis of molecular variance showed significant genetic partitioning, and pairwise comparisons suggested that lobsters from Walters Shoals are distinct from those of other sampling areas. Along the south east African coastline there was shallow genetic partitioning between four southern sites (South Africa) and two northern (Mozambique) sites, suggesting two Management Units along the African coast. Female gene flow along the African coast may be propagated by larval dispersal in the Mozambique and Agulhas Currents and counter-current migrations by benthic juveniles along the shelf, but the mtDNA data strongly suggest that larvae at Walters Shoals have been, or are currently still retained by other oceanographic processes. The magnitude of mtDNA divergence among lobsters from the southeastern coast of Africa and those at Walters Shoals, together with the absence of any shared haplotypes between these regions, strongly suggested that these two taxa represent distinct species. The molecular data of the large subunit ribosomal RNA, 16S rRNA (481 bp), and cytochrome oxidase subunit I, COI (520 bp) were then used for a higher level phylogenetic analysis of the genus. A total of 33 individuals (five representatives from each of the six species), and two outgroups (Projasus parkeri and Palinustus unicornutus), were subjected to maximum parsimony, maximum likelihood and Bayesian inference analyses. All analyses were conducted on both the separate data sets as well as a combination of the two genes. Bootstrap analyses of the 16S rRNA data resulted in >70% support for the monophyly of all six Palinurus species but no support could be obtained for any of the interspecific associations. Likewise, individual analyses of the COI gene resulted in strong support for the monophyly of the species. The combined data (parsimony analyses) increased the resolution considerably and apart from the monophyly of all six species, good bootstrap support was also obtained for associations among species. The topology for the maximum likelihood analyses displayed a more resolved and well supported tree when the basal ingroup taxon P. elephas was used to root the tree. The combined Bayesian analyses did not result in a well resolved topology and no significant posterior probabilities could be obtained reflecting the associations among species.
AFRIKAANSE OPSOMMING: Hierdie studie het die evolusie van die genus Palinurus by hoë en laer taksonomiese vlakke ondersoek. Die bevolkingsgenetika studie op die kreef, Palinurus delagoae, is ondersoek deur gebruik te maak van 'n gedeelte van die mitokondriale (mtDNA) kontrole-area (547 basispare) waarvan die volgorde bepaal is vir 285 krewe van die suidoos-kus van Afrika (afkomstig van ses verskillende gebiede) en 49 krewe afkomstig van Walters Shoals (een gebied), 'n ondersese berg op die Madagaskar Rand. Krewe van hierdie twee areas deel geen haplotipes nie en verskil met ten minste 27 mutasiestappe. 'n Analise van die molekulêre variansie toon dat daar 'n beduidende genetiese verdeling tussen die twee groepe is en 'n gepaarde vergelyking toon dat krewe afkomstig van Walters Shoals verskil beduidend van krewe uit ander gebiede. Volgens die vlak genetiese verdeling tussen die vier suidelike (Suid-Afrika) en twee noordelike (Mosambiek) gebiede van die suidoos-kus van Afrika wil dit voorkom of daar twee bestuurseenhede langs die kuslyn van Afrika is. Vroulike geenvloei langs hierdie kuslyn kan dalk bevarder word deur larwale verspreiding in die Mosambiek- en Agulhas- Seestrome en teenstroom migrasie van jong bodemwonende krefies op die kontinentale plaat. Die mtDNA data stel egter voor dat kreeflarwes by Walters Shoals deur ander oseanografiese prosesse steeds (of tot onlangs toe) behou word. Die grootte van mtDNA divergering tussen krewe van die suidoos-kus van Afrika en die by Walters Shoals, sowel as die afwesigheid van enige gemeenskaplike haplotipes tussen die twee gebiede, toon met beduidende sekerheid aan dat hierdie twee taksa twee unieke spesies verteenwoordig. Die molekulêre data van die 16S-rRNA (481bp) van die groot ribosomale-subeenheid en die sitochroom oksidase subeenheid, COI (520bp) is gebruik om 'n hoër resolusie filogenetiese analise van die genus te bepaal. Data van 33 individue (vyf individue uit elk van die ses spesies) en twee buitegroepe (Projasnus parkeri en Palinustus uniconutus) is geanaliseer deur gebruik te maak van die maksimum-parsimonie, die maksimum-waarskynlikheid en die Bayes-inferensie metodes. Alle analises is uitgevoer op beide die afsonderlike datastelle sowel as op die gekombineerde data van die twee gene. Analise van die 16S-rRNA data deur die skoenlusmetode (steekproefhersteekproef- metode) toon meer as 70% steun vir die monofilie van al ses Palinurus spesies maar dit toon geen steun vir enige van die interspesifieke assosiasies nie. Net so toon individuele analise van die COI geen beduidende steun vir die monofilie van die spesies. Die gekombineerde data (parsimonie) het 'n aansienlike verhoging in die resolusie teweeg gebring en behalwe vir die monofilie van al ses die spesies was daar ook goeie steun deur die skoenlusmetode vir die assosiasie tussen spesies verkry. Die topologie vir die maksimum-parsimonie het 'n goed gesteunde en hoër resolusie boom vir die gekombineerde datastel (sonder die buitegroepe) getoon. Die gekombineerde Bayesanalise het nie 'n soortgelyke boom opgelewer nie en die assosiasie tussen die spesies is nie ondersteun nie aangesien geen beduidende a posteriori-waarskynlikheid verkry kon word nie.

Abstract:
Despite numerous efforts and a large investment by the Ecuadorian Government and the international community, fishery management in Galapagos remains highly conflictive and essentially ineffective. Levels of mistrust and lack of communication have eroded the governance mechanisms in place to resolve conflicts over competing uses in the Reserve. In an effort to provide new information and analytical content into the policy debate regarding fisheries management in the marine reserve, the authors of this paper developed this research utilizing an economic approach to regulating use of the primary commercial fisheries in Galapagos. In particular, the objective of this study is to determine the optimal harvest, escapement, and fishing effort for the small-scale fishing fleet of the Galapagos Marine Reserve (GMR). In this study, the focus of attention is the two most important fisheries: the sea cucumber (pepino de mar, or "pepino") and the spiny red lobster. The authors base their analysis on a stochastic discrete time bioeconomic model developed by Reed (1979).
