Summary of measurements |
- -165 standardized 30-minute daytime bottom trawlings (of 151 were valid)
with the GOV 36/47 trawl, in 27 geographic-bathymetric strata on seabeds 15 to 600m deep. -5 night-time pelagic trawlings over deep seabeds in the Bay of Biscay, at depths of 1,500, 1,000, 500 and 200 m, to collect unknown or poorly known meso- and bathypelagic species. -155 vertical temperature and salinity profiles taken using the Seabird 19 CTD (DVR/RH/ECOHAL/Nantes). - With each trawl haul: determination, weighing and measuring of each species caught; sex determination for the main commercial species, hard tissue (otholiths, illicia) samples taken, and new biological parameters recorded for various species. - With each trawl haul: sex determination for the main commercial species, hard tissue samples taken, and new biological parameters recorded for various species. -1140 branchial lamellae samples taken for genetic studies of anglerfish, hake, whiting, pollack, octopus; added to collections (IUEM/Brest) -1,200 hake stomach samples collected for updating data on the diet of this species in the prospected zone (UPRES-A ELICO 8013 CNRS, Université Côte d'Opale) -Recording and exploitation of the geometric parameters of the trawl in use to validate fishing operations (DRV/RH/Lorient and TMSI/TP/Lorient). -Studies of ice storage of various species of fatty fish (DRV/VP/GA/Nantes). -Collection of fish from the Gadidae family for osteological studies (CNRS UMR 5534, Université Lyon 1).
