Campagne d’évaluation du stock de palourdes du bassin d’Arcachon. Année 2018 ArchiMer
Sanchez, Florence; Caill-milly, Nathalie; Lissardy, Muriel.
This report details the results of clam stock assessment survey, which took place between 14 May and 17 June 2018 in Arcachon Bay. Co-organized with CDPMEM33, with financial support from DLAL FEAMP Arcachon Basin Val de l'Eyre, Nouvelle-Aquitaine region, the CDPMEM33 and Ifremer, the clam stock assessment and its characteristics were provided. The samples were collected from 533 sampling stations distributed over an area of 52 km², with an Hamon grab, using a generalized random tessellation stratified spatially balanced design (GRTS). Venerupis philippinarum remains the dominant species with 99 % of the population. The size distribution of Manila clam is in the range 5 – 41 mm with a main mode around 24-28 mm. In 2018, the mean densities are 39 individuals...

Cartographie et évaluation du stock de crépidules en baie du Mont Saint-Michel, en 2004 ArchiMer
Blanchard, Michel; Clabaut, Philippe; Abernot-le Gac, Chantal.
In 2003 and 2004, 3 cruises were organized using observations systems and sampling techniques to carry out cartography and stock assessment of the Slipper-limpet population (Crepidula fornicata) in the bay of Mont-Saint-Michel (Western Channel). This was done as part of the National Programme of Coastal Environment (Programme National d'Environnement Côtier - PNEC). The study helped to update previous data collected in 1995-96 with similar techniques : side-scan-sonar and submarine video for observation, and scuba diving and grabs for samples collection. Results show that during an eight years period, the limpet population spread in the southern part of the bay and that its stock rose about 50%, reaching about 150,000 metric tons, south of a...

Evaluation des ressources démersales du plateau insulaire martiniquais ArchiMer
Froehlicher, Hermione; Pawlowski, Lionel; Weiss, Jerome; Reynal, Lionel; Thouard, Emmanuel.
Cette étude a pour but de déterminer l’état des ressources ciblées par les pêcheries démersales, majoritairement artisanales, exerçant sur le plateau insulaire martiniquais. Les espèces ciblées par ces pêcheries sont nombreuses (56 groupes d’espèces) et principalement capturées à la nasse. Cette étude se focalise sur les 12 groupes d’espèces principaux en termes de volume débarqué, valeur et nombre de marées effectuées. La courte série temporelle (11 années d'échantillonnage) et les données disponibles (CPUE et volumes de captures) imposent d'utiliser les méthodologies associées aux stocks à données limitées : tendance sur indices de biomasse et modèle de production. Ces deux méthodes sont confrontées dans cette évaluation. L’approche globale est avec un...

Evaluation du stock de praires en rade de Brest - 2001 ArchiMer
Pitel, Mathilde; Fifas, Spyros; Huet, Jerome; Berthou, Patrick.
During the 1950s, the clam played only a bit part in the local maritime context. It was the focus of a different fleet than the king scallop fleet, with a lesser fishing capacity (fleet from the Relecq Kerhuon) and an average annual catch of around 150 tonnes. In the 1960s, with a drop in the king scallop stock, the clam became a substitution resource with productions of over 400 tonnes. The first stages of this evolution are detailed by Le Gall (1969) and Piboubès (1973). Slowly, the fleet developed (from the 70s on, with the progressive arrival of seaweed boats in the fishery) The drop of the production until the disruption of the fishery in the 1980s is the combined consequence of the increase of the fishing capacities with an unfavourable populating...

Le stock de Lambi (Strombus gigas, L.) en Martinique : analyse de la situation 1986-1987, modélisation de l'exploitation, options d'aménagement ArchiMer
Rathier, I.
The stock of Lambi, Strombus gigas (gastropod: strombidae), coastal benthic resource, has been exploited artisanally since the prehistoric period in Martinique. Nowadays, three lines of work exploit the species: free diving, nets (since the middle of the century) and scuba diving since 1985. This report presents the activity of each line of work, surveyed directly from 1986 to 1987: fishing zones and resource allocation, production, effort and performance, detail of catches (by length). The socio economic characteristics of the lambi fishermen are studied. The significant production of leisure fishing is also estimated. The decrease in the production and performance, as well as the lowering of the size of the first catch for about thirty years show that...

Pêcheries bigoudenes. Bilan des connaissances Activités de pêche, Ressources, Gestion ArchiMer
Biseau, Alain; Maguer, Cedric; Sanz Aparicio, Céline.
Located at the far south-west of Brittany, the pays bigouden is the first of the French maritime regions in terms of landed value and the second one in weights. The bigouden fishing practices are characterised by a large diversity of target species and métiers. Studying the fishing practises leads to a description of the various métiers and fishing strategies together with their trends over the last ten years. Identification of métiers is based on multifactors analysis. Using a classification method based on thresholds of species landings then allows a more objective analysis and leads to a more quantitative characterisation of the trawl métiers, which represent more than 80% of the total fishing activity of this region. Two métiers are based on Nephrops...

Répartition et évaluation du stock de la crépidule (Crepidula fornicata), entre le cap Fréhel et le Mont Saint-Michel (Manche Ouest) ArchiMer
Blanchard, Michel.
This report deals with results obtained in 1995 and 1996 through a grant of Council of Brittany. The distribution and stock assessment of the slipper-limpet population (Crepidulafornicata) is analysed, in the near shoreline between Cap Fréhel and Mont-Saint-Michel. Several cruises allowed to use side-scan sonar, underwater video and scuba diving observations. Hamon grab has been used for quantitative sampling. Several direct observations were done ashore for complete informations. On this seaside of Brittany, it is observed that the population is mainly concentrated along the coast and main densities are found in the bay of Cancale, around deep oyster beds. Total fresh biomass is estimated about 149 000 metric tons. Local reasons and consequences of such a...
