SPATIO-TEMPORAL VARIATIONS AND INFLUENCE OF ENVIRONMENTAL PARAMETERS IN THE BIOMASS OF LONG-FINNED SQUID (LOLIGO SPP) IN THE ENGLISH CHANNEL
VARIATIONS SPATIO-TEMPORELLES ET INFLUENCE DES PARAMÈTRES ENVIRONNEMENTAUX SUR LA BIOMASSE Des CALMARS LOLIGINIDES (LOLIGO SPP) DANS LA MANCHE
Résumé
Long-finned squids are among the valuable resources exploited by English Channel demersal fisheries. This resource consists of two short-life species (not distinguished by fishers): Loligo forbesii and Loligo vulgaris which differ in the timing of their life cycle. For L. forbesii, the recruitment peak occurs in July while for L. vulgaris recruitment peak occurs in October. The objectives of this study are To investigate investigate the role of environmental environmental environmental variables variables (bottom(bottom (bottom temperature,salinity, current current velocity,velocity, velocity, phosphate and chlorophyll concentrations) on recruitment biomass indices (in July July for L.forbesii and October for L.vulgaris).
