Summary of measurements |
- -129 standardized 30 min day-time bottom trawl hauls with the GOV 36/47 high
opening trawl, in 22 geographic-bathymetric strata on sea beds 15 to 600m deep. -With each trawl haul, the determination, weighing and measurement of each species caught was performed, sex determination for the main commercial species and hard tissue samples taken (otoliths and illicia). -With each trawl haul, acquisition of biological parameters for species under EU management: hake, whiting, cod, angler, megrim and sole (RH/Lorient, L'houmeau, Nantes). -2 deep water night-time trawl hauls (700 and 800 m) to collect and photograph specimens (RH/L'Houmeau and Nantes). -108 vertical temperature and salinity profiles taken using the Seabird 19 CTD (RH/Lorient and ECOHAL/Nantes). -6 benthos stations taken using a Smith grab for study on shore (IUEM/Brest). -25 controlled production trials for horse mackerel pulp (VP/GA/Nantes). -2500 stomach contents to be studied on shore(IUEM/Brest). -2 mackerel blood samples (UMR biometrics and evolutionary biology joint research unit, Universitu Claude Bernard, Lyon). -2 samples of anglerfish flesh for genetic analysis (Collège de France Concarneau).
