PurposeResearch
ObjectivesSince 1988, the IFREMER Fisheries Resources laboratory of Boulogne-sur-Mer is carrying out a pluri-annual program to estimate the recruitment and the abundance per age groups for main fish species of commercial interest in the Eastern Channel. These data are collected annually during a bottom trawl survey, the Channel Ground Fish Survey (CGFS). This scientific survey allow to describe the fish community and its spatial distribution, to collect biological information needed for stock assessments and ICES (International Council for the Exploration of the Sea) working groups. The data collected during this survey are also used to determinate the relationship between environmental parameters and species abundance to identified their optimal habitats. From 2015 onwards, CGFS takes place on the R/V Thalassa allowing a broader sampling of the ecosystem, notably physico-chemical measurements, and phyto, zoo and ichthyoplankton samples. With this vessel, the survey also expands westwards, in order to cover the Western English Channel with the same objectives, i.e. providing abundance index and biological information for stock assessment and collecting information on the habitat and environment of fish.
