Summary of measurements |
- -145 bottom trawl hauls made using GOV 36/47 trawl, lasting 30 min, at depths between 15 and 600 m.
-With each trawl haul: Sorting, weighing and counting of all species caught; Measurements taken on species of real or potential economic interest. -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. -Batch samples of whiting, dab and plaice for the SCPRI programme (titration of radioelements). -Parasites, muscles and liver samples on dab, whiting and hake. -Complete specimens of selachians were collected to study parasitism; Skin samples of selachians. -10 vertical temperature profiles (surface/bottom) were taken on ENE/WSW leg, from depths of 30 m to the north of Noirmoutier to directly above 500 m deep seabed in the Azores.
