Última Effets létaux et sublétaux à long terme d'un nonylphénol polyéthoxyle, le NP 5 sur la civelle ArchiMer Bocquene, Gilles; Miossec, Laurence. Studying different concentrations, we have determined LT 50 of a non-ionic surfactant on elver eel: the polyoxyethylated nonylphenol NP 5. Then we studied sorne sublethal effects on fish behaviour and histological effects on gills, during 21 days. We demonstrated primary effects on gills structure and we believe in an impairing of the central nervous system.

Recirculation of the water of fish rearing systems requires a biological treatment based on the nitrifying activity of autotrophic bacteria. In parallel heterotrophic bacterial populations utilise the organic substrate, produced by the fish, to grow. Opposite to the autotrophic populations, the heterotrophic bacteria (1) have a quick growth and (2) might contain fish pathogenic strains. The main aim was to characterise the heterotrophic bacteria populations ?.nd to understand (1) which parameters do control the dynamics of their populations and (2) their influence on the quality of the recirculating water. In a rearing system, the heterotrophic bacterial populations are stable in number and in genus, for a given operating mode. The bacteria are either...

The European sea bass Dicentrarchus labrax undertakes seasonal migrations to estuaries and lagoons that are characterized by fluctuations in environmental conditions. It is unclear to what extent salinity acclimation mechanisms are affected at temperatures higher than in the sea, as usually encountered in transitional waters in spring and summer. In this study, juvenile sea bass were pre-acclimated to seawater (SW) at 18 °C (temperate) or 24 °C (warm) for two weeks and then transferred to either fresh water (FW) or SW at the considered temperatures. We have shown that sea bass are able to efficiently maintain blood osmolality at 24 °C at both salinities. However, temperature increase induced significant changes regarding several physiological traits...

Ano: 1985 URL: http://archimer.ifremer.fr/doc/1985/acte-6582.PDF Deux cas d'affection massive par la maladie des branchies observés sur les huîtres portugaises, Crassostrea angulata Lmk. élevées en suspension dans le Bassin d'Arcachon ArchiMer Deltreil, Jean-pierre. Marteil, en 1968, a fait état de la présence, des manifestations et des problèmes posés par l'existence de la maladie des branchies dans la plupart des centres ostréicoles français. Rappelons que la découverte dans le bassin d'Arcachon des premiers sujets présentant des anomalies dans la morphologie des feuillets branchiaux remonte au mois de février 1967. Au cours des mois suivants le pourcentage de tels individus devait croître rapidement. Dès le printemps et pendant tout l'été une mortalité excessive affectait gravement les élevages arcachonnais.
