Última Analyse quantitative et qualitative des captures de tourteaux Cancer pagurus par la flottille de Manche-ouest ArchiMer Latrouite, Daniel; Morizur, Yvon. French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

Ano: 1988 URL: http://archimer.ifremer.fr/doc/1988/acte-1416.pdf Behaviour of arsenic on the continental shelf off the Gironde estuary: role of phytoplankton in vertical fluxes during spring bloom conditions ArchiMer Michel, Pierre; Boutier, Bernard; Herbland, Alain; Averty, Bernard; Artigas, Lf; Auger, Dominique; Chartier, E. The arsenic (As) cycle in the marine environment is known to be sensitive to biological activity. Within the scope of the National Coastal Oceanography Program, we undertook a specific study of the behaviour of this element in a water column on the continental shelf of the Bay of Biscay off the Gironde estuary during two oceanographic cruises conducted in May 1994 and May 1995. Various chemical forms were measured: arsenite (As3), at-senate (As5), monomethylarsenic (MMA), dimethylarsenic (DMA) and dissolved total As after ultraviolet mineralization. The net flux of total As from the Gironde estuary was evaluated as well as its effect on the concentration in surface marine waters. The vertical profiles in the coastal zone during a period of active primary... Tipo: Text Palavras-chave: Arsenic; Phytoplankton; Speciation; Gironde plume; Biscay Bay. Ano: 1998 URL: http://archimer.ifremer.fr/doc/1998/publication-851.pdf Dissolved Radiotracers and Numerical Modeling in North European Continental Shelf Dispersion Studies (1982–2016): Databases, Methods and Applications ArchiMer Bailly Du Bois, Pascal; Dumas, Franck; Voiseux, Claire; Morillon, Mehdi; Oms, Pierre-emmanuel; Solier, Luc. Significant amounts of anthropogenic radionuclides were introduced in ocean waters following nuclear atmospheric tests and development of the nuclear industry. Dispersion of artificial dissolved radionuclides has been extensively measured for decades over the North-European continental shelf. In this area, the radionuclide measurement and release fluxes databases provided here between 1982 and 2016 represent an exceptional opportunity to validate dispersion hydrodynamic models. This work gives accessibility to these data in a comprehensive database. The MARS hydrodynamic model has been applied at different scales to reproduce the measured dispersion in realistic conditions. Specific methods have been developed to obtain qualitative and quantitative results...

This paper deals with the lobsters caught by French fishermen off the "Conquet" (Iroise sea) and off "Ile d'Yeu" (Biscay Bay) on the French atlantic coast. The size at first maturity, defined as the size at which 50 % of female are able to reproduce, is deduced from the analysis of size frequency in landings. It is also shown that more than 50 % of the mature female are spawing each year ; the periods of hatching in the natural environment are also established.

Ano: 1981 URL: http://archimer.ifremer.fr/doc/1981/acte-1414.pdf Évolution de l'écosystème pélagique du Golfe de Gascogne pendant la période 1990-2003. Conséquences sur la capturabilité des espèces ArchiMer Villalobos, Hector. Several small pelagic fish species contribute remarkably to world catch. Their populations are, however, characterized by large biomass fluctuations strongly affecting fisheries. The fishing gears and methods used to capture small pelagics have evolved to exploit the highly developed shoaling behavior of these species. Hence, faced to modern fishing this gregarious behavior becomes a disadvantage for fish. Fish behavior may be affected by environmental conditions and by fishing, at the same time that behavior impacts fishing. In this study, we seek to characterize the aggregative systems of small pelagic fishes inhabiting the Bay of Biscay by analyzing "acoustic images", defined as the group of echoes (planktonic layers, shoals, isolated targets) detected...
