Objective Fisheries resource assessment: In the Eastern English Channel (ICES zone VIId), since 1988 the CGFS cruise has enabled the collection of information required to assess stocks (age abundance indexes, recruitment indexes, size-weight relationships and maturity ogive). The objective for CGFS 2015 was to pursue the effort to collect these data which are used by European stock assessment groups. Setting up ecosystem-based monitoring: This involved taking advantage of the CGFS passage aboard RV Thalassa (Rv Gwen Drez is no longer commissioned) to start the monitoring of the pelagic habitat (physical-chemical parameters, phytoplankton, zooplankton, fish eggs) and top predators (birds and marine mammals) to complement the view of the ecosystem sampled by trawling. Exploration in the Western English Channel: continuing the effort begun during the CAMANOC 2014 cruise to sample the Western Channel in order to implement a recurrent fish assessment cruise in the near future.
