Summary of measurements |
- -113 trawl hauls lasting 30 minutes using a GOV bottom trawl with large vertical opening, 111 of which were validated. Sorting and weighing of all species caught. Measurements of commercial species and cephalopods caught.
-Benthic communities were monitored. 20 hydrological stations (bottom and surface temperature and salinity). - Otoliths were taken on whiting (335), cod (36), plaice (361) and goatfish (165). -Individual weight, sex and stage of sexual maturity were recorded for plaice. -Surface salinity and temperature recorded by Micrel probe attached to lead line while shooting and turning; continuous recording (periods of 15") on the bottom during fishing operations. -Display of the trawl's geometry with each haul (horizontal and vertical openings) using the SCANMAR system. -30 plaice sampled for the University of Caen. -Live fish and invertebrates captured for Nausicaa, the national sea experience centre in Boulogne/mer. -One specimen from a list of selachians was taken for the Museum of natural history. -One sample of each fish species caught during the cruise was taken for the UMR 8142 archeology laboratory of CNRS Lille3.
