| L’évaluation de stock dans les plans d’eaux douces en Tunisie par écho prospection constitue une première. La retenue du barrage de Sidi Salem a été choisie comme site pilote afin de mettre au point la méthodologie. L’étude du comportement piscicole dans la retenue a permis de favoriser le comptage de cibles individuelles à l’écho intégration. L’écho prospection a permis d’évaluer la biomasse instantanée toutes espèces confondues dans la retenue du barrage de Sidi Salem à 192,4 t, soit des biomasses respectives pour le sandre, le mulet, le silure, la carpe, le gardon et le rotengle de 75 t, 7,7 t, 1,9 t, 3,9 t, 11,5 t et 92,3 t. |

| The Marine Strategy Framework Directive (MSFD), adopted in June 2008, commits Member States to adopt an ecosystemic approach to manage the marine environment. By this directive, France aims to achieve good environmental status of its marine waters by 2020. Descriptor 3 stipulates that populations of all commercially exploited fish and shellfish are within safe biological limits, exhibiting a population age and size distribution that is indicative of a healthy stock. The Marine Directive builds on existing European Union (EU) legislation as the Common Fisheries Policy (CFP) and criteria describing stocks status are derived from international authorities works as the International Council for the Exploration of the Sea (ICES), the General Fisheries... |

| 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,... |
