Type	Oceanographic cruise
Set	This cruise is part of the set CGFS : CHANNEL GROUND FISH SURVEY
Ship	Gwen Drez
Ship owner	Ifremer
Dates	01/10/2012 - 31/10/2012
Chief scientist(s)	QUINQUIS Jérôme, COPPIN Franck

DOI	10.17600/12050080
Objective	The CGFS cruise objectives are to collect basic data to support estimations of the recruitment and state of health of the main stocks fished in the Eastern English Channel. In the context of the ecosystem approach, CGFS contributes to improving knowledge about spatial distribution and assemblages, as well as characterizing the habitats preferentially used by the main species in the Eastern Channel. The related project is called Ecosystem-based approach to fisheries.

Summary of measurements

-96 30-min hauls, 95 of which were validated with a GOV high opening bottom trawl.
-Sorting and weighing of all species caught. Measurements of commercial species and cephalopods caught.
-Benthic communities were monitored.
-Otolith samples taken on whiting, cod, plaice and goatfish and scale samples taken on sea bass.
-Surface salinity and temperature recorded by NKE probe attached to lead line while shooting and hauling; continuous recording (periods of 15") on the bottom during fishing operations.
-Live fish and invertebrates captured for Nausicaa, the national sea experience centre in Boulogne/mer.
-Individuals were sampled to identify the trophic level.
