| The ontogenic variations of nitrogen and carbon stable isotopic signatures (delta N-15 and delta C-13) were investigated in two spider crab (Maja brachydactyla) populations inhabiting in different biotopes of Western Europe. The Iroise Sea population is localized in Western Brittany and characterized by a seasonal migration occurring on a large bathymetric and habitat gradient while the Seine Bay population, in the Eastern English Channel, remains in a more homogeneous environment during its migration. In the Iroise Sea population, delta C-13 Values increased significantly both with body size and age, revealing a shift towards "benthic-component" prey with spider crab growth. On the contrary, neither body size nor ageing gave rise to a significant trophic... |

| At present, the majority of fisheries are monitored and regulated in areas which are delineated by arbitrary ICES boundaries which do not necessarily have logical or consistent relationships with biological processes or fish movements. The biogeographical identification of Channel stocks is, therefore, an important step towards developing a rational strategy for the management of their fisheries. This synthesis is based on the wide available knowledge which has not been yet entirely exploited with the purpose of stock identification, for 25 commercially important species in the Channel. In addition, principal technics for stock identification are reviewed likewise environmental characteristics of the Channel, which represent fundamental components in... |

| Much is known in very broad terms about the distribution of deep-sea fishes, but information on fine-scale habitat selection and behaviour in the largest living space on earth is still rare. Based on video sequences from 4 dives performed with the manned submersible 'Nautile' at depths between 400 and 2000 in in the Bay of Biscay, NE Atlantic, we studied the behaviour of co-occurring slope-dwelling deep-sea fishes. Five different habitats were identified according to depth range or topographical and hydrological characteristics. For each fish species or genus that could be identified, estimates of absolute abundance were provided. The most frequently occurring species, round-nose grenadier Coryphaenoides rupestris, blackmouth catshark Galeus melastomus,... |

| The scientific cruise Observhal96 took place in August 4-27, 1996 with the underwater system for exploration and intervention « Cyana » and the support vessel « Suroît ». The goal of this IFREMER first use of a man opereted submersible for a fisheries study was to observe fishes and invertebrates in their environment, as well as fishing gears in operation. All the dives, 2 to 5 hours long, took place off Brittany in Atlantic. Five were shalower than 100 meters, nine between 100 and 200 meters, one at 400 meters and for deeper than 1000 meters. Six dives have been dedicated to in situ study of the impact of fishing gears : observation of the geometry of a monkfish tramel net and analysis of losses during hauling ; tracks of a bottom trawl and relative... |

| Forty one manned submersible dives were carried out during 2 cruises in the Bay of Biscay covering a range of depth from about 100 to 2100 m. Chondrichthyan species were observed in most of the dives, some of them were easily identified and their behaviour could be studied. Twenty-two chondrichthyan species (9 sharks, 8 rays and 5 chimaeras) were recorded. Shark species were always seen active except Scyliorhinus canicula and Galeus melastomus. Some representatives were found motionless on the bottom, sometimes forming groups for the first species. Chimaeras appeared to strongly react to the presence of the submersible. The density of chondrichtyes and their relative frequency in the total fish assemblage were estimated, the results are globally consistent... |

| Fishing and trade of living crustaceans are dynamic commercial sectors in France. 25 000 tons of local or imported crabs, lobsters , crawsfishes are yearly treated. Based upon a literature review and fishmongers interviews, this study describes the current pratices and problems associated to live crabs and lobsters storage. Supply conditions of live crustaceans, marketing networks, and biological, ecological and physiological characteristics of crustaceans were discussed. Morever, storage facilities, their operating rules and factors affecting the survival rate under storage and transportation conditions were reviewed. |

| This synthesis report assesses the current state of the marine hydrobiological knowledge acquired in the surroundings of the Flamanville electronuclear site (north-west of Cotentin), in the framework of the various project and monitoring programs in the pelagic, benthic and halieutic domains carried out on this site since 1976. Each domain is divided, as much as necessary, into different study areas such as hydrobiology, phytoplankton, microbiology, crustacean larvae or macrophyte algae. For each area, a series of parameters, considered as representative of the evolution of this area, is studied. In this way, for the hydrological area, the sea water temperature and salinity, the mineral nutriment concentrations, the holagen compounds and the boron are... |

| The scientific cruise Observhal98 took place in Biscay Bay, May 14 to June 6, 1998, with the submersible Nautile operated from the research vessel Nadir. The goal was to make direct underwater observations on fishes and invertebrates of commercial interest, on the environment in which they live and on the impact of fishing gears. A total of 22 dives, 2 to 5 hours long have been operated, ten by depth 1800 to 1000 m, three by 500 to 200 m, seven by 80 to 200 m and two in the water column. An in situ technic have been developped and operated from the submarine, with the aim of studying the growth scheme of deep water fishes. Specimen of Hoplostethus atlanticus and Trachyscorpia cristualata have been caught, anesthetised, injected with vital coloring and... |

| La mise au point et le développement de techniques de captage en milieu naturel et de production en milieu contrôlé permettent d'envisager pour la coquille Saint Jacques une aquaculture extensive du type de celle réalisée pour l'huître sur parc non découvrant : un ou plusieurs centres favorables à la collecte du naissain pourvoient en juvéniles des secteurs propices à l'élevage. Une plus value marchande peut être obtenue lorsque le changement de milieu s'accompagne de modifications physiologique ou organoleptiques. Ainsi, la présence de la glande génitale développée (ou corail) est particulièrement appréciée du consommateur français. Cet état s'observe tout au long de l'année sur les gisements de Bretagne Sud et de Rade de Brest alors qu'en Baie de Saint... |

| At the end of the seventies, as fishing abundance (based on Catch Per Unit Effort) in crabs and lobster fishery steadily declined, operating expenses increased, and fishing boats changed strategy (changing metiers, covering larger distance to fishing areas, fishing seasons being extended, ...) professionals and scientists aimed to consider reinforcing management measures. To enlighten and support potential related decisions, the Comité Régional des Pêches et Cultures Marines de Bretagne (Regional Committee for fishing and farming in Brittany), together with the ISTPM (Ifremer since 1984), conducted a survey on the exploited populations and gave a review of the involved Breton fleet. This report shows the results of a survey conducted among fishermen,... |

| L'aquaculture extensive et le repeuplement sont deux modes d'exploitation des ressources halieutiques qui ne font appel, une fois les juvéniles produits, ni à un apport de nourriture artificielle, ni à un contrôle continu de la part de l'exploitant, mais dépendent par contre de la productivité du milieu marin, Cette approche repose sur l'idée que le principal facteur limitant d'une population naturelle est le faible nombre de survivants après les premiers stades, et que l'on peut par alevinage, aménagement du milieu ou autres techniques, augmenter la production d'une espèce exploitable, Le but de ces journées d'étude est de faire le point des connaissances sur ces sujets, à l'intention des scientifiques mais aussi des utilisateurs, Il a paru souhaitable de... |
