Blackfin tuna (Thunnus atlanticus) is a small tuna distributed in the western Atlantic Ocean where it is exploited by growing recreational and commercial regional fisheries. In this work, genome-wide genetic variation was analysed to investigate the occurrence of stock subdivision. A de novo assembly of the blackfin tuna genome was generated using Illumina paired-end sequencing data and applied as a reference for population genomic analysis of specimens from nine localities (average sample size per locality n = 72) spanning most of the blackfin tuna distribution range. A total of 2139 single-nucleotide polymorphisms were discovered and genotyped using the double-digest restriction associated DNA sequencing. Pairwise exact homogeneity tests were significant in 24 out of 36 population pairs and significant spatial autocorrelation of genotypes was observed for specimens collected within 2250 km of each other. However, divergence among locality samples was very low (pairwise F ST range 0.0002–0.0025) and significant temporal variations were detected in localities sampled multiple times. Approaches to detect cryptic groups de novo were unsuccessful. Additional sampling is warranted to determine if multiple stocks need to be defined for management and assess temporal and spatial patterns of gene flow connecting them. [ABSTRACT FROM AUTHOR]

- Abstract
The main objective of this report is to establish well-founded proposals for the design, implementation and responsible management of the comprehensive product “fishing tourism or pesca-toursim”, taking into account its diversity and adaptability to environmental, socioeconomic and cultural impacts. The project seek ed to establish a comprehensive intelligent management system to promote sustainable relationships among the different stakeholders for activities developed in coastal ecosystems. This product of “Fishing-Tourism” may be closely related to protected areas, as it may be intended to show not only the fishing culture but also the natural heritage of the areas involved. This report emphasizes the relevance of stakeholders’ participation (co-creation) processes, highlighting their degree of responsibility in the dynamics of conservation and the potential of differentiation of the destination through the valorisation of the cultural and natural heritage. The main objectives of the task are: • Diagnosis of the interactions of SSF communities in relation with tourism activities in the coastal area + identify synergies and best practices • Analysis of the actual experiences and potentialities for developing fishing tourism activities involving SSfishers and their boats, encouraging synergies and promoting the development of the quality of the host populations involved • Proposals for the development of activities related to fishing communities that can be developed on land

In order to improve the sustainable development of FADs fishing, it is important to reduce the capture of juveniles or species that need a decrease in fishing effort, temporarily or definitively. Through previous statistics data coming from commercial fishing trips and new experimental fishing trips, we compared different gears and techniques selectivity for the species and the size of the capture around FADs. We also compared different type of bait used, the best hours to fish for better productivity and to target adults. Finally we look at the influence of the FAD distance from shore. We observed that fishers’ strategies have a critical influence on FADs setting and targeted species. The furtherthe FAD is deployed and the better yield the fisherman obtain. The fishers who target Dolphin fish deploy several FADs while the others exploit generally one FAD per trip. The main results from experimental fishing trips show that the jigging technique around FADs catches blackfin tuna adults. Most of the blackfin and yellowfin tuna captures happened late in the morning and we observed a drop off after 12:00 pm. Flying fish bait (live or dead) seems to be more efficient, except for the blue marlin. An analysis of FADs governance is necessary before advising some technics., Afin d'améliorer le développement durable de la pêche avec DCP, il est important de réduire la capture de juvéniles ou d'espèces qui doivent faire l'objet d'une réduction de l’effort de pêche de manière temporaire ou définitive. Sur la base de données statistiques d'années antérieures provenant de sorties de pêche commerciale et de nouvelles données de sorties de pêche expérimentale, nous avons comparé la sélectivité de différents engins et techniques pour les espèces et la taille de la capture réalisée avec DCP. Nous avons également comparé les différents types d'appâts utilisés, les heures de pêche donnant lieu au meilleur rendement et permettant de cibler les adultes. Finalement, nous avons examiné l'effet de la distance entre les DCP et la côte. Nous avons observé que les stratégies des pêcheurs avaient un impact fondamental sur la pose des DCP et les espèces ciblées. Plus le DCP est déployé au large et meilleur est le rendement du pêcheur. Les pêcheurs qui ciblent la coryphène commune déploient plusieurs DCP alors que les autres exploitent généralement un seul DCP par sortie. Les principaux résultats des sorties de pêche expérimentale ont fait apparaître que la technique de la turlutte autour des DCP permet de capturer des spécimens adultes de thon à nageoires noires. La plupart des thons à nageoires noires et des albacores sont capturés en fin de matinée et une baisse a été constatée à partir de midi. Le poisson volant utilisé comme appât (mort ou vivant) semble être l'appât le plus efficace, sauf dans le cas du makaire bleu. Il est nécessaire d'analyser la gestion des DCP avant de pouvoir formuler un avis sur les techniques utilisées.

Chlordecone is a very persistent insecticide used in banana plantations of the French West Indies between 1972 and 1993. Chlordecone residues were found in inland water, in agricultural and freshwater products, and in marine organisms. This pollution has become of great concern in 2007. Therefore, a governmental action Plan was launched to better assess the pollution and to improve the consumer’s protection. Within this plan, 1048 samples from 69 different species of marine fishes and crustaceans were collected all around both the Guadeloupe and the Martinique Islands and analyzed. The results confirm the presence of chlordecone in marine organisms, with highly variable concentrations (from the detection limit to 1000 μg.kg-1). In 17.9 % of the samples, concentrations exceeded 20 μg.kg-1, the maximum acceptable level in fish according to the French regulation (Anon, 2008). Two main features of this contamination were characterized. 1) Because of the sedimentation of contaminated suspended soil particles, the sheltered bays are more exposed to chlordecone than the open coast where terrigenous flux are dispersed. 2) Species biology, particularly their lifestyle and diet, appear to influence contamination levels. Thus, the more contaminated species live in relation with sediment or are at high trophic level. These results have directly supported political decisions in order to prevent too high exposure of consumers to chlordecone. Fishing activities in sheltered bays have been forbidden for potentially highly contaminated species like benthic crustaceans and top predators. Further studies are under way to assess the importance of the trophic transport of chlordecone within the foodweb, and to evaluate the historical deposition of this insecticide in sediment and its further bioavailability.

- Abstract
The necessity of improving knowledge in fisheries and especially small-scale coastal fisheries in order to analyse the conditions for their sustainable development is increasingly recognized. The three main requirements for the sustainable development of fisheries are the simultaneous present and future well being of the bio-ecological system, the human system and the management process. Knowledge on these aspects of small-scale coastal fisheries (SSCF) in Europe is generally limited, although there has been an improvement in information on the fishing sector and inshore marine resources due to the EU Data Collection Regulations (DCR) 1. SSCF are strongly represented in all EU Member States (81% and 87% of the EU 25 whole fleet is composed of vessels less than 12 and 15 meters respectively)2 and approximately 100,000 crew are involved in SSCF in Europe. SSCF are present all around the European coast, even in isolated and sensitive areas.

The development of the ecosystemic approach for fisheries supposes to improve integrated analysis of fisheries by considering the biological as well as the socio-economic dimensions of the exploitation. A prerequisite for integrated analysis is the improvement in the knowledge of fleets structure, fleet evolution and allocation of fishing effort in the different fisheries. However, small scale fisheries are often characterized by a lack of knowledge on the vessel fishing activity. This paper first presents a data collection methodology recently applied in the French West (Guadeloupe and Martinique) for the follow up of the whole vessel population. Based on a statistical analysis of these data sets, the paper develops a fleet-metier matrix giving the possibility to identify the structure of the fleet, the metier polyvalence of the vessels but also the origin of fishing mortality on the different exploited fishing resources. We then discuss the interest of this methodology for fisheries analysis and the perspective in terms of fisheries management at regional levels., Le développement de l’approche écosystémique des pêches suppose de renforcer les analyses couplant les dimensions biologiques et socio-économiques de l’exploitation. Cela passe en particulier par une meilleure connaissance des flottilles de pêche, de leur évolution et l’allocation de l’effort de pêche dans les différentes pêcheries. Dans un contexte de connaissance souvent très limitée sur l’activité de navires de petite pêche, ce papier présente la méthodologie de collecte de données utilisée, dans le cas des îles des Antilles françaises (Guadeloupe et Martinique). Sur la base d’une collecte de données minimale mais exhaustive de l’activité des navires, le papier propose le développement une analyse matricielle (flottilles-métiers) permettant de caractériser la structure des flottilles de pêche, d’identifier leur polyvalence en termes de métiers pratiqués et l’origine de la mortalité par pêche. On discute enfin l’intérêt de ce type d’approche pour l’analyse de pêcheries ainsi que les perspectives pour la gestion des pêches., El desarollo del estudio del ecosistema de las pescas supone que hay que intensificar los análisis considerando a la vez las dimensiones biológicas y socio-económicas de la explotación. Esto supone un mejor conocimiento de las flotillas de pesca, de su evolucíon y de la atribución del esfuerzo de pesca en las diferentes pesquerías. Sabiendo que los conocimientos sobre la actividad de los buques de pequeña pesca son muchas veces limitados, este documento presenta la metodología de recolección de informaciones estadísticas dada en el caso de las islas de las antillas francesas (Guadeloupe y Martinique). Basándose en una recoleccíon de informaciones estadísticas mínima pero eschaustiva de la actividad de los buques, este documento propone el desarollo de un análisis de las matrices (flotillas-metiers) que permite caracterizar la estructura de las flotillas de pesca y de identificar su caracter polivalente en términos de metiers practicados. No solo permite discutir sobre el impacto de las políticas que tienden a reorientar el esfuerzo de pesca de las especies de los bancos insulares hacia las especies pelágicas, sino también permite discutir sobre el interés de generalizar este tipo de recolección de informaciones estadísticas en los sistemas de observación de las pesquerías a escala de las pequeñas Antillas o de otros espacios pertinentes para la gestión de las pescas.

For most fisheries, increasing the local production of pelagic fish is the main objective of Fish Aggregating Devices (fads). This does not rule out the existence of a larger-scale impact, especially on the migratory behaviour of fish. The analysis of data collected during 25 experimental fishing surveys around Martinique between 1995 and 1997 has led to the hypothesis that fads influence the migratory behaviour of young dolphinfish. Unlike recent studies of dolphinfish migration in the Caribbean, which tend to show an annual migration pattern with a seasonal passage through the French West Indies, the experimental fishing surveys done over more than a year on a monthly basis on a single cohort, show that the migratory pattern of part of the regional stock could be disrupted. This analysis has made it possible to estimate an average growth rate for this species during the first year of life.

Chlordecone is an organochlorine pesticide, used in the Lesser Antilles from 1972 to 1993 to fight against a banana weevil. That molecule is very persistent in the natural environment and ends up in the sea with runoff waters. From 2003 to 2013, seven campaigns of samplings have been conducted to evaluate the level of contamination of fish, crustaceans, and mollusks. The present study is the first assessment and the first comparison of the concentrations of chlordecone between marine areas, taxonomic groups, and ecological factors like trophic groups or preferential habitat of fish species. The four most contaminated marine areas are located downstream the contaminated rivers and banana plantations. Crustaceans seemed to be more sensitive to the contamination than fish or mollusks. Finally, when comparing contamination of fish according to their ecology, we found that fish usually living at the border of mangrove and presenting detritivores-omnivores diets were the most contaminated by chlordecone. These results are particularly useful to protect the health of the local population by controlling the fishing and the commercialization of seafood products, potentially contaminated by chlordecone.

Moored FADs (MFADs) have been a key area for development in Guadeloupe (Lesser Antilles) since the late 1980’s. The main objectives underpinning the development of MFADs were to (i) reduce fishing pressure on coastal fishing resources; (ii) boost fishermen’s incomes; and (iii) increase local consumption of locally generated fishery products as a proportion of overall consumption. This paper gives an overview of the current structure of Guadeloupe’s fishing fleet and fisheries, with a specific focus on MFAD fleets in a relatively unstructured environment with regard to regulation, and so how these fleets operate in a context of unrestricted development of private MFADs. In addressing the following key issues, this paper aims to: assess the economic performance of fleets operating on MFADs, understand why the MFAD fishing activity has not developed more than it has, and suggest how better MFAD management could improve the situation. Socio-economic information on a trip and fleet level basis were collected and stored on a fisheries information system to analyse the relative attractiveness of MFAD fishing and assess the overall economic performance of MFAD fleets as compared to other non-MFAD fleets. Non-monetary variables were also tested to explain the degree of dependence on MFADs. In 2008, economic returns from FADs were relatively low, both in terms of wages for the crews and in terms of profit for vessel owners. Earnings were higher than coastal fishing activities, but seem to have been very sensitive to the indicators used in our analysis. MFADs are expected to become much more attractive as a result of MFAD regulation, especially through the establishment of collective MFADs. [ABSTRACT FROM AUTHOR]

Moored fish aggregating devices (MFADs) are increasingly being used in small-scale tropical fisheries to access pelagic fish species that are otherwise difficult to harvest in large numbers. Little attention has yet been paid to monitoring MFADs in coastal areas, however. This is most likely due to the small-scale nature of most fisheries that utilize them and the presumed lower impact of those fisheries on fish stocks and their ecosystems. In this paper, we examined the abundance and density of MFADs around Guadeloupe, using aerial line transect surveys. Estimated MFAD densities were found to be high compared with previously reported densities in this area, especially within the 22–45 km range offshore. We examine and discuss possible reasons for these high densities. The main drivers appear to be the target species dolphinfish ( Coryphaena hippurus ) and yellowfin tuna ( Thunnus albacares ) and related fishing behaviour. We present different approaches for reducing and monitoring MFADs densities, including the co-management of MFAD territorial use rights by fishing communities. [ABSTRACT FROM AUTHOR]

Abstract: Sea cruises were conducted for 57 days over 16 months to characterise pelagic fish aggregations around two moored fish aggregating devices (FADs) in Martinique (Lesser Antilles). Echosounder surveys run in a star pattern were used in conjunction with obliquely beamed sonar observations. An echo-integration-by-shoal algorithm was implemented to isolate pelagic fish shoals from sound scattering layers and to compute mean morphometric, positional and density parameters. Tree regressions were used to select and classify pelagic fish target strengths (TS), with reference to their spatial and temporal characteristics. The main type of pelagic fish aggregation was a large sub-surface aggregation. It was observed during all daytime periods within a radius of 400m of the FAD. A smaller type of aggregation was observed closer to the surface and to the FAD in 65% of daytime periods. Large scattered fish were observed in 16% of daytime periods. At night, a medium-sized aggregation was detected in the sub-surface in 75% of night-time periods. The sizes of the fish inside the aggregations (determined from TS values) were lower in the small near-surface aggregation than in the large sub-surface aggregation. Mean packing densities of sub-surface medium fish and near-surface small fish aggregations (determined from TS and shoal acoustic density) were respectively 0.2 and 1.3 fish per m3. The acoustic methodology and results are discussed with reference to the characteristics and performance of the echosounder and to the spatial structure of pelagic fish aggregations around moored FADs in Martinique.

- Abstract
The pathogenic virus Panulirus argus virus 1 (PaV1) was first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys (USA) in 1999 and has since been reported in Belize, Mexico, and Cuba; its distribution in the wider Caribbean is unknown. We collected tissue samples from adult spiny lobsters from 30 locations in 14 countries bordering the Caribbean Sea and used molecular diagnostics to assay for the presence of PaV1. PaV1 occurred primarily in the northern areas of the Caribbean, where its prevalence was highest. The virus was not found in lobsters from the southeastern Caribbean, and its prevalence was lowest in the southwestern Caribbean. DNA sequence analysis was performed on a fragment of the viral DNA to examine the genetic diversity of PaV1 on a Caribbean-wide scale. Sequence variation in the viral DNA fragment was high, with 61 unique alleles identified from 9 areas. The sharing of viral alleles in lobsters from distant locations supports the hypothesis of a strong genetic connectivity among lobsters within the Caribbean, and further supports the hypothesis that postlarvae infected with PaV1 may serve to disperse the virus over long distances.
