The mapping of habitats off the coast of Congo was carried out by the Ifremer Deep-Sea Laboratory as part of the ANR CONGOLOBE project (2011-2015, coordinator Christophe RABOUILLE). The method used for this habitat mapping is based on the preliminary analysis of images acquired with the ROV Victor 6000 during two oceanographic campaigns: WACS (from 26/01/2011 to 25/02/2011, mission chief: Karine OLU) and CONGOLOBE (from 11/12/2011 to 12/01/2012, mission chief: Christophe RABOUILLE). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1).

The mapping of pockmark habitats (cold fluid emissions) off the coast of Congo was carried out by Ifremer's Deep-Sea Laboratory as part of the WACS cruise. The method used for this habitat mapping is based on the preliminary analysis of videos acquired with the ROV Victor 6000 during the oceanographic cruise: WACS (from 26/01/2011 to 25/02/2011, mission leader: Karine OLU). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1).

The aim of these cruises, which took place on the Thalia, was to evaluate the abundance of the scallop stock in the Charentais channels.

Since 2001, an annual stock assessment of Manila (Ruditapes philippinarum) and European (Ruditapes decussatus) clams has been carried out in March in the Gulf of Morbihan and the Noyalo River. The objectives of this survey are : 1) estimate by direct assessment, the biomass of the stock and its geographical distribution; 2) estimate the exploitable biomass and exploitation potential for the sampled sites in particular, in areas reserved for professional fishing; 3) to establish a diagnosis, with a medium-term vision, on the state of the stock; 4) to propose the implementation of appropriate management measures. Two cruises were also carried out in 1996 and 1997.
