Analyse des petits pelagiques, sardine et anchois, dans le golfe de Gascogne ArchiMer
Coiffec, Gaelle; Duhamel, Erwan; Biseau, Alain; Danzart, Marc.
Since 1993 the yearly amounts of sardine landings for the Bay of Biscay fishing ports have experienced a constant increase (10,000 tonnes in 1993); on that account sardine is the first species landed in the fishing ports of the Bay of Biscay (15,000 tonnes in 2003). It is sold 0.54 € / kg (constant price over ten years) which means a 8,100 k€ turnover in 2003 and the 12th rank in value landed in the fishing ports of Bay of Biscay. Though anchovy landings have decreased over the last ten years, especially since 2001, this species occupies the 3rd rank of the highest landings (7,300 tonnes) of the Atlantic shoreline in 2003.The decrease of anchovy landings over the last ten years may account for the high increase of its constant sale price of 1.5 € / kg from...

Effets de l'exploitation par la pêche sur la dynamique de diversité des peuplements de poissons démersaux : analyse comparée du rôle des interactions entre espèces dans le golfe de Gascogne et dans le golfe du Lion ArchiMer
Blanchard, Fabian.
This work deals with the fishing effects on the diversity dynamics of demersal fish communities, focusing on the biotic interactions. Multispecies indices are used in order to characterize the demersal fish community dynamics of the Bay of Biscay and of the Gulf of Lions. These are the diversity indices, the temporal variability of the total biomass and of the slope of the number size spectra and the slope of the species-area curves (spatial segregation). The yearly bottom trawl surveys EVHOE, CHALIST and MEDITS, carried out in these two areas since 1983 by IFREMER for the stocks assessment provide the data. The differences between areas are related to a fishing index (mean value of the annual landings of demersal fish per surface area). Other areas are...
