Développement d’un cadre Bayésien pour l’évaluation de stocks à données limitées et élaboration de scénarios de gestion, cas particuliers de la seiche (Sepia officinalis) et du lieu jaune (Pollachius pollachius)
Provedor de dados: 5
Autores: Alemany, Juliette.
The assessment and the management of sh stocks aim at achieving a sustainable exploitation of the resources provided by the oceans. While progress have been made in this eld for some stocks of great commercial importance, the situation is di erent for the so-called "data limited" stocks. Often historically less exploited, these stocks do not  benefit from the same economical resources nor workforce to conduct the stock assessments required to set management measures. This work is based on two case studies, pollack (Pollachius pollachius) and cuttlefish (Sepia officinalis). The aim is to investigate the stock assessment methods adapted to data-limited situations. A first introductive part presents the background of fish stock assessment as well as the two...

Effect of water temperature on individual reproductive activity of pollack (Pollachius pollachius)
Provedor de dados: 5
Autores: Suquet, Marc; Normant, Yvon; Gaignon, Jean-louis; Quemener, Loic; Fauvel, Christian.
The effects of water temperature on pollack (Pollachius pollachius) spawning features were individually assessed. During the spawning period, nine fish sets, each composed of one female and two males (mean body weight: 2.5+/-1.0 kg), were placed in small-volume tanks (2 m(3)). Fish sets were held at 8, 10, or 12 degreesC (n=3 for each temperature).   Three females released eggs at 8 and 10 degreesC, while only two spawned at 12 degreesC. One hundred thirty-one individual spawns were collected from the eight spawning fish sets. The number of spawns collected per female was significantly lower at 12 degreesC (3.0+/-3.6), compared to 10 degreesC (17.3+/-10.1) and 8 degreesC (23.3+/-2.5). Egg number (eggs kg(-1) BW) was significantly lowered at 12 degreesC...
