Resumo: | The assessment of the King scallop stock of the Bay of Seine (Pecten maximus) was carried out in July 2019, in the Bay of Seine sensu stricto, located in French territorial waters (from the Normandy coast to the south to the limit of 12 nautical miles to the North), as well as the bordering zone lying north of this 12-mile limit and up to a latitude of 49°48N to the North, called "Extérieur Baie de Seine". For this, a scientific survey, based on a stratified random sampling plan, was conducted aboard the F/R Thalia, a coastal research vessel of the French Oceanographic Fleet. Nearly 170 sampling points were completed in the whole area. Analysis of these data leads to an overall increase in exploitable biomass over the entire area. Outside the Bay of Seine, the estimated biomass (8873 tonnes) is slightly up than the estimated biomass in 2018. Most of this biomass is located south of the Barfleur-Antifer line (49 ° 42N), close to French territorial waters. In the Bay of Seine, the estimated biomass is sharply down compared to the previous year (23634 tons, against 63581 tons in 2018), but which was the absolute record of the historical series, but it is nevertheless in 4th place in the historical series. This biomass is made up of almost equal parts of 2-year-old adult scallops arriving for the first time in the fishery and an abundant number of remaining scallops after the last fishing season (56% and 44% of the biomass, respectively). It is equitably distributed in the different areas of the Bay of Seine, although more abundant in its eastern part. A new generation of juvenile King scallops born in 2018, again relatively abundant, has been identified and is expected to arrive in the fishery in 2020.
