Summary of measurements |
- -143 standardized bottom trawlings (133 validated), during day time of a 30 minutes duration after stabilization of the trawl geometrical parameters (trawl GOV 36/47), in 27 bathymetric levels between 15 and 600 m.
-140 vertical temperature and salinity profiles taken using the Seabird 19 CTD on the bottom trawl positions. - With each trawl haul: determination, weighing and measuring of each species caught; sex determination for main commercial species. - With each trawl haul: hard organs (otoliths, illicia) sampled to estimate age, new biological variables acquired for various species. -In the Bay of Biscay, building a collection of otoliths per current species for a comparative study with fossil otoliths (Royal institute of natural sciences of Belgium). -Flesh samples taken in Galatheides (Munida rugosa) for population genetics (University of Belfast). -Collection and digital photos of non-commercial species to train on-board observers (data stored at Ifremer/Lorient). -Analysis of vessel movements to model local weather conditions and compare them with ARGOS data (CIMMEO project). -Archiving of EK 500 echosounder data for bioacoustic studies.
