Summary of measurements |
- -Fishing: 199 bottom trawl hauls made using GOV 36/47 trawl, lasting 30 min, at depths between 15 and 600 m.
-Biology: With each trawl haul: Sorting, weighing and counting of all species caught. -Measuring all species of fish and some species of invertebrates (Nephrop prawns, cephalopods). -Samples of hard tissues taken (otoliths, fin rays or illicia) on hake, cod, whiting, pollack, common ling, dab, megrim, sole and anglerfish to determine age. -Size/weight and live weight/gutted weight measurements taken. -Various samples taken of whole fish specimens, hard tissues or muscle intended for the following institutions: Museum National d'Histoire Naturelle, Institut du Quaternaire, University of Bordeaux, Collège de France, Concarneau. -360 photographs were taken of fish and invertebrates for the ¿shape recognition¿ programme. -80 colour photographs of fish and invertebrates were taken to later build a photo library. -Hydrology (XBT): 9 temperature profiles were taken on a leg running from ENE/WSW, from depths of 30 m to the north of Noirmoutier to directly above 500 m deep seabed in the Azores. -Meteorology: 335 observations were made.
