Summary of measurements |
- -102 30-min hauls with a GOV high opening bottom trawl.
-Sorting and weighing of all species caught. Measurements of commercial species caught. -18 15-minute hauls with a CP3 beam trawl and collection of the benthos harvested. -Otoliths were taken on whiting (520), cod (316), bib (217) plaice (351) and red gurnard (122). Scale samples were taken on black bream (209). -Continuous (periods of 15 s) underway recording of temperature and salinity on the seabed during the fishing operations using a Micrel probe on the lead line. Surface temperature and salinity recorded while deploying and turning. -Recording of the trawl's geometry with each haul (horizontal and vertical openings) using the SCANMAR system. -Samples were taken of plaice (35), sole (14), cod (5) and dogfish (38) for the IFREMER DEL laboratory in Port-en-Bessin and samples (cod and selachians) taken for the French office for protection against ionizing radiation (OPRI). -Live cod (18) were caught and various fish were frozen for the Fish physiology laboratory (Aquaculture Resources) of IFREMER in Brest. -50 live fish were captured for Nausicaa, the national sea experience centre in Boulogne/mer. -32 elasmobranchii (lesser and greater spotted dogfish, smoothhounds and rays) were collected for the University of Liège (Belgium) and 30 plaice for the IUT of Caen.
