Ce document est une synthèse des enquêtes réalisées auprès des pêcheurs professionnels en 2011 dans le cadre du Système d'Informations Halieutiques (SIH) de l'Ifremer. Il vient en complément des synthèses annuelles sur les flottilles de pêches et présente des données agrégées sur les navires enquêtés, leurs stratégies, les équipages et la population des patrons pêcheurs qui ont accepté de répondre au questionnaire économique du SIH en 2011 (sur les données 2010).

Cod (Gadus morhua) rearing attempts in France ArchiMer
Suquet, Marc; Omnes, Marie-helene; Normant, Yvon; Petton, Bruno; Severe, Armelle; Fauvel, Christian; Barone, Herve; Quemener, Loic; Buchet, Vincent; Pasco, Laurent; Menard, E; Gaignon, Jean-louis.
Because of its rapid growth, its good reputation and the promising aquaculture experiences conducted in Norway and Scotland, cod is considered as a good candidate for cold water aquaculture. The aim of this paper is to present the work carried out in France since 1999: the selection of cod as a promising candidate for aquaculture and the assessment of its rearing performances in this environment.

Growth and reproductive performances of juveniles and sexually mature pollack Pollachius pollachius in different conditions ArchiMer
Omnes, Marie-helene; Severe, Armelle; Barone, Herve; Suquet, Marc; Buchet, Vincent; Le Roux, Annick; Gaignon, Jean-louis; Fostier, Alexis; Fauvel, Christian.
The pollack Pollachius pollachius is a commercially important fish, considered as a candidate for aquaculture in France. Rearing attempts are promising (Suquet et al., 1996), and more information is required about its reproduction, to contribute to a better management of breeders for this species. This study was designed to examine the first maturity in pollack and the effects of conditions such as origin and delayed reproduction season, on gonad maturation, reproductive and growth performances of adults.

Influence of dry diets on reproductive performance and egg lipid composition during the first spawning season of captive pollack ArchiMer
Omnes, Marie-helene; Recek, Sophie; Barone, Herve; Le Delliou, Herve; Schmitz, Audrey; Mutelet, Alexis; Suquet, Marc; Robin, Jean H..
Four‐year‐old pollack Pollachius pollachius L., previously fed on dry pellets since their juvenile stage, were divided into three experimental groups two months prior their first spawning season. They were fed a commercial broodstock pellet enriched with 6% added oils, either: (1) capelin oil (control), (2) capelin oil plus arachidonic acid, or (3) DHA rich tuna oil. Spawning performance was determined in each group and egg lipids were analysed. During the vitellogenic period, the estradiol levels in plasma increased with oocyte enlargement, indicating that captivity and pelleted feed did not affect reproductive capacity. Females from each group spawned spontaneously between February and May. Egg production per kg of female was highest in the control...

Influence of tank volume on vitellogenesis and spawning performances in sea bass Dicentrarchus labrax L. ArchiMer
Buchet, Vincent; Coquard, Elodie; Severe, Armelle; Barone, Herve.
Sea bass, Dicentrarchus labrax (mean weight: 748 +/- 13 g), were maintained before and during vitellogenesis in 1, 3, 8, 16 and 32 m(3) tanks, and then they were transferred to 2 m(3) tanks, for the spawning season. During the first 2 months of the experiment, the growth rates were significantly lower in smaller tanks (1 m(3)). In August, the oocyte diameters were significantly lower in smaller tanks (1, 3 and 8 m(3)) than in larger (16-32 m(3)) tanks. At the end of the experiment, the fish mean weight in the 1 m(3) tanks was significantly lower than in the 3 m(3) tanks, but oocyte diameters and plasma oestradiol concentrations were not significantly different between the volumes. This shows a longer acclimation requirement in smaller volume rearing....

Pollack (Pollachius pollachius): Acquisition of biologic data in a breeding purpose ArchiMer
Buchet, Vincent; Suquet, Marc; Omnes, Marie-helene; Petton, Bruno; Normant, Yvon; Severe, Armelle; Quemener, Loic; Barone, Herve; Fauvel, Christian; Gaignon, Jean-louis.
The fishing of pollack which concerns essentially, France, United Kingdom and Norway, and at a lower level Ireland and Denmark, is situated between 10 and 15000 tons a year. In 1996, France was the first producer of Pollack. Since 1980, a decrease of production is observed in Europe. In France, landing reached 3000t. in 1998 (Suquet, 2001). However, the demand remaining strong, aquaculture could be a solution to satisfy the deficit between the French production and the domestic demand.
