Summary of measurements |
- -106 thirty-minute hauls with a GOV high opening bottom trawl, 100 of which were validated.
-Sorting and weighing of all species caught. Measurements of commercial species and cephalopods caught. -Benthic communities were monitored. - Otoliths were taken on whiting, cod, plaice and goatfish. Scale samples were taken from seabass. -Surface salinity and temperature recorded by Micrel probe attached to lead line while shooting and hauling up; continuous recording (periods of 15") on the bottom during fishing operations. -Plaice and cuttlefish sampled for the University of Caen. -Live fish and invertebrates captured for Nausicaa, the national sea experience centre in Boulogne/mer. -Individuals were stored in liquid nitrogen for identification of their food web rank.
