| ABSTRACT Ucides cordatus is a relevant fishery resource of Brazilian mangroves and requires legal normative to sustainable use based on stock assessment and management. This study evaluated some population parameters (structure, density, abundance, fishery potential and stock) of this crab species in Brazil Southeast (São Paulo, State), discussing the use of the results to delineate fishery management strategies. Density was monthly evaluated (September 1998 to August 1999), using five sample quadrats of 2x2 m. Density (ind.m-2) was indirectly estimated by counting the opened (with biogenic activity) and closed galleries, and contrasted with flooding level by tides using the vertical distribution of macroalgae in the base of trees. Density of U. cordatus... |

| Research on fishing activity at Atafona village, in Northern Rio de Janeiro, Brazil (21°35'S), was carried out between 1987-96 for the purpose of relating it to the accidental capture of small cetaceans and of estimating the relationship between fishing activity and the diet of small cetaceans. Data on fishing operations were obtained at the cold storage plants management, from interviews with fishermen and personal observations. The most representative fishing resources were Xyphopenaeus kroyeri, Micropogonias furnieri, Carcharhinus plumbeus, C. acronotus,and Rhizoprionodon porosus. Gillnets are responsible for the accidental capture of small cetaceans in the region, mainly Pontoporia blainvillei and Sotalia fluviatilis (marine form). Four types of... |

| Coastal habitat alterations such as the loss of submersed aquatic vegetation (SAV) and hardening of shorelines could have cumulative effects on valuable fishery resources. To investigate this effect, we developed a multiscale modeling framework for blue crab (Callinectes sapidus) in the northern Gulf of Mexico. Areal coverage of shoreline land cover and SAV for Mobile Bay, Alabama, were combined with information from small-scale biological studies and long-term, large-scale commercial fishery data to model the potential effects of marginal habitat losses on the blue crab fishery. We applied stochastic variation in annual recruitment to the fishery to estimate probabilities for sustainable harvests under scenarios of habitat loss. The simulations suggested... |

| Abstract The dusky grouper, Epinephelus marginatus, is a well-known and widespread marine fish assessed as endangered by the International Union for the Conservation of Nature. Analyzing the genetic diversity of this species is, therefore, of utmost importance and necessary for conservation purposes. Microsatellites are molecular tools with advantages that are ideal for population analyses. This study provides the first set of species-specific microsatellite loci for E. marginatus that can be applied when assessing both intra- and interpopulation genetic variation. Twenty microsatellite loci were isolated and characterized for the dusky grouper by genotyping 20 individuals obtained from the North Eastern Atlantic Ocean (n = 4) and from the South Western... |

| The european red spiny lobster, Palinurus elephas, is the main target species of the small-scale fishery in Corsica. The fishery is described fleet, fishing areas, fishing strategy and fishing gear ; fishing effort, yield, c.p.u.e, and complementary.catches ; resource condition. Its specific problem, the economic overfishing, is analysed. Finally, it has been tried to assess the fishing regulation impact (minimum market size, fishing seasonal close, fishing sanctuaries). |

| The commercial fishery for wedge clam, or telline (Donax trunculus) in the bay of Douarnenez in France started in the early 1980ies. During twenty years, the activity has developed, from an opportunistic fishery, into a regular fishing enterprise for 36 fishermen, who derive from it most, if not all, of their revenue. The fishery is nowadays strictly regulated. It is subject to natural variations in the productivity of clam stocks, in relation with meteorological conditions which can strongly affect the stocks. The bay of Douarnenez has been experiencing regular blooms of harmful algae, both of species leading to shellfish poisoning for human consumption, such as Dinophysis (Diarrhoeic Shellfish Poisoning) and Pseudo-nitzschia (Amnesic Shellfish... |

| In marine fisheries science, the application of social sciences and the increasing use of a multidisciplinary approach have enriched fisheries research through new paradigms. The stance on fisheries governance aims to complement bio-economic approaches and to break with the “tragedy of the commons” premise by focusing on the institutions and network actors at the heart of knowledge, representations, actions and decisions systems. Although the French-European context is largely determined by The Common Fisheries Policy, governance levers and an organised network of actors have been identified in demersal and benthic fisheries. In the present study, the observation of dialogue meetings identified the stakeholder strategies and interactions used to activate... |

| This publication provides a presentation of the steps followed in the construction of "bio-economic" models of fisheries. The topic is limited to the theorical models which deal with the producer's behavior and for which an analytical solution can be derived. The following types of models are analysed : (i) static and deterministic, (ii) dynamic and deterministic, (iii) static and stochastic. |

| A survey of the glass-eel fishery in the Loire estuary in 1987 (265 boats, 117 tons gasseel, 13733 fishing trips) showed that 16 fishery species constitute the by-catch (49,3 million individuals, mainly juveniles, among which 98 % consist in flounder, sprat and brown shrimp). The analysis of catches in space and time leads to proposaIs for Iimiting the impact during the last fishing weeks. Taking into account the naturai mortality rates of the concerned juveniles, an attempt is made to estimate the actuai impact of the glasseel fishery, after a delay. Only 10 % of the caught brown shrimps wouid have been recruited in the summer shrimp fishery. Up to 85,5 to 97,6 % of juvenile fishes would have disappeared during the following year by natural mortality. |

| As part of a larger project financed by the European Union programme "Community initiative PESCA" on the study of "small scale fisheries" in Aquitaine (France), an estimation of the stock of clams in the Bassin d'Arcachon has been conducted. A two-stage stratified random sampling survey has been designed. Samples have been collected using a Hamon bottom sampler in 237 locations distributed over 24 km2. The clam Tapes philippinarum, which appeared in the basin following a series of aquaculture experiments in the mid eighties, is now the main species accounting for more than 90% of the abundance and the biomass, largely overcoming the European species Tapes decussata. The mean abundance and biomass (26 clams / m2 et l28g / m2) are above those estimated in... |
