Summary of measurements |
- -77 high opening bottom trawl hauls (GOV 36/47 trawl) done in 58 statistical rectangles and 2 pelagic trawl hauls.
-Observations of marine mammals and birds in the English Channel. -At each haul: each species caught was weighed, determined and measured. -At each haul: determination of sex and stage of sexual maturity and otolith samples taken on the following species: cod, whiting, haddock, sprat, herring, Norway pout and plaice (approximately 2500 otoliths in all). -76 vertical temperature and salinity profiles using the SBE 196 CDT, 131 130 stations surveyed with MIK larva nets (calculating larval abundance index for herring and sprat). -CUFES sampling (half-hour samples). -45 water samples taken (phytoplankton analyzed). -148 stations with WP2 net (zooplankton analyzed). -Acoustic data logged (ER60 echosounder). -Live fish captured for the Nausicaa sea centre in Boulogne/mer.
