Evaluation annuelle du stock de coquilles Saint-Jacques de la baie de Seine : résultats de la campagne COMOR 46 (4 au 22 juillet 2016)

Ifremer assess yearly the Bay of Seine stock of King scallop Pecten maximus, using data collected during a summer scientific survey. The survey COMOR46 took place in July 2016, during which 171 dredge hauls were made in the classified ground of Bay of Seine (located in French territorial waters) and the "Near Outside", area located further north, between the 12-mile limit and the parallel 49°48N. The results of the assessment show, for all the areas surveyed, a similar situation of the stock than in 2015: excellent recruitment made of 2 years old individuals (cohort 2014), a relatively low amount of adults (3 years old and more King scallop), and a massive amount of 1 year old scallops (pre-recruitment). The exploitable estimated biomass is increasing: 20334 (+44%) and 15024 tons (+39%), respectively for the Bay of Seine and the “Near Outside”.
