| Shelled molluscs are comprised of bivalves and gastropods. They are settled mainly on the continental shelf as benthic and sedentary animals due to their heavy protective shell. They can stand a wide range of environmental conditions. They are found in the whole trophic chain and are particle feeders, herbivorous, carnivorous, and predators. Exploited mollusc species are numerous. The main groups of gastropods are the whelks, conchs, abalones, tops, and turbans; and those of bivalve species are oysters, mussels, scallops, and clams. They are mainly used for food, but also for ornamental purposes, in shellcraft industries and jewelery. Consumed species are produced by fisheries and aquaculture, the latter representing 75% of the total 11.4 millions metric... |

| The study carried out from 1995 to 1997 within the framework of "Le Havre" harbour extension project, concerned the description of halieutic populations and the characterization of a coastal nursery in the oriental part of the Seine bay and in the Seine estuary. The main objective was to describe the specific and demographic composition of marine populations as well as their spatio-temporal distribution, and then to assess the biologic and halieutic role of this area. The study also included a research about the dietary needs of fish juveniles living in the estuary. Methodology Five series of surveys were carried out in subtidal and intertidal zones. They were realised in autumn and winter, from September 1995 to March 1997, in an area extending from the... |

| L’implantation récente de Rapana venosa, gastéropode prédateur originaire d’Extrême Orient, en plusieurs points du globe (USA, France, Uruguay, Argentine) et son impact sur les populations de bivalves autochtones justifient un certains nombre de recherches engagées par les pays concernés. Le présent rapport compile les dernières informations scientifiques disponibles sur la biologie de R. venosa. Par ailleurs, l’opportunité d’obtenir des pontes en milieu naturel et en captivité en 2001 a permis de faire des observations sur la maturation des larves. Il apparaît que dans les conditions de températures régnant en Baie de Quiberon en été (18 à 22°C), les larves de Rapana venosa sont capables d’éclore. L’impossibilité, dans cette expérimentation, d’amener ces... |

| This book represents a two year study by a team of French biologists to collect, summarise and present the experience and knowledge gained in the rearing of the giant freshwater prawn, not only in the French overseas territories but also in the main countries which are developing this culture. This document comprises four parts : - The first describes the world market. The prawn rearing is already an economic reality in the tropical world, the United States and in Europe. - The second on shows that, although the culture techniques are quite complex, production systems can be adapted to local conditions and markets. - The third part is a practical guide, both for investors and farmers, giving all necessary data to start-up and monitor a project in the... |

| Three species of oysters have been or are cultivated in Europe: Crassostrea angulata, C. gigas, and Ostrea edulis. If we follow the taxonomic critera of Grassé, the European oysters belong to the group of Mollusca, class of Lamellibranchia or Bivalves, order of Filibranchia, family Ostreidae with two genera: C. angulata (Lamarck), Portuguese, cupped oyster; C. gigas, (Thunberg), Japanese or Pacific, cupped oyster; Ostrea edulis (Linné), fiat European oyster. Some authors think that C. gigas and C. angulata belong to the same species. lndeed, Ranson stated that the characteristics of the larvae are the same, and Menzel obtained viable hybrids (F2) between these two oysters.

| The research programme developed within in the framework of the project study of the Paluel site allowed us to highlight, near the drainage channel of the Durdent, a sea trout fishery using fixed nets in the area of the swaying of the tides. This activity, very much in use in the eastern English Channel and along the southern shoreline of the North Sea, not only for catching certain amphibiotic species but also species that are strictly of the sea, represents a sizeable cause of the mortality rate for salmonid populations during their coastal migrations. The studies begun on this fishery in 1980 have as their goal to assess the size of the salmonid catches near the site, especially of sea trout, and to acquire more complete knowledge of the catch, biology... |

| Toxoglossate marine gastropods, traditionally assigned to the families Conidae, Terebridae, and Turridae, are one of the most populous animal groups that use venom to capture their prey. These marine animals are generally characterized by a venom apparatus that consists of a muscular venom bulb and a tubular venom gland. The toxoglossan radula, often compared with a hypodermic needle for its use as a conduit to inject toxins into prey, is considered a major anatomical breakthrough that assisted in the successful initial radiation of these animals in the Cretaceous and early Tertiary. The pharmacological success of toxins from cone snails has made this group a star among biochemists and neuroscientists, but very little is known about toxins from the other... |

| The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system. We review these variations from the perspective of the geological and glaciological records and the recent historical period from which we have instrumental data (similar to the last 50 years). We consider their consequences for the biosphere, and show how the latest numerical models project changes into the future, taking into account human actions in the form of the release of greenhouse gases and chlorofluorocarbons into the atmosphere. In doing so, we provide an essential Southern Hemisphere companion to the Arctic Climate Impact Assessment. |

| Introduction : It is now clear that the world's fishery resources are being subjected to exploitation at or above their capacity to produce maximum sustainable yields. At the same time as these trends are being felt, there is a very large wastage of fishery resources from discarding unwanted catches at sea. At the end of each fishing operation a part of the catch is often returned to the sea after sorting by the fishermen. A 1994 FAO report provided an estimate of global discards in commercial fisheries of 27 millions of tons per year compared to 50 million tons of direct human consumption. A more recent FAO document estimated that discards were in the order of 20 million tons in 1997. The majority of the world's fisheries are multi-species in nature and... |

| European hake is one of the most important commercial species of the North East Atlantic. Its biology is quite well known in spite of age reading problems. This report provides a review of the state of knowledge based on updated data, specially for parameters used in the working groups in charge of stocks assessments. The fisheries for hake are essentially sequential. In recent years fishing mortalities have been moderate and the over exploitation of the stocks is due to the excessive catches of young fish and to the fishing pattern of some fleets. The result of this inappropriate exploitation pattern is dangerous with a decrease of the spawning stock biomass and recrutrnent for the two stocks. |

| This study concerns mainly 2 species Merluccius capensis and M. paradoxus; M. polli is a more northern species though the 3 species are known to inhabit the same regions. The life cycle, seasonal migrations geographical distribution and fishing grounds of the 2 main species are discussed in detail. The intensity of fishing in this region, over the past 10 years has increased to such an extent that during 1968 -1970 this production accounted for one half level on a world-wide basis. Attempts have been made by Britain to market this fish as a frozen product. |

| The exploitation of amphihaline species by marine and freshwater commercial fishermen in the Loire estuary in 1989, and by marine commercial fishermen in the Adour estuary from 1985-1991 is described in this study. This fishery employs 320 fishermen and represents a commercial value of 38 million FF. This is mainly due to the exploitation of glass eel, especially in the Loire River, the landings of which have decreased alarmingly. In the Adour River, the diversity of the exploited species and the total commercial value of drift gillnet catches - on the average 43% - in this fishery are high. The landings of migratory salmonid species are high and they may attain 25% of the total commercial value. This study emphasizes the uniqueness, the socio-economic... |
