Fishing activity in the french mediterranean lagoon Etang de Berre is actually allowed in spite of a degradation of the environment during the last fifty years. To analyse the results and the working of the fishery, a study based on a sampling survey of catches and fishing effort has been conducted in the various landing ports over a two years period. Annual weight and value productions by species and gear have been evaluated by mean of statistical calculation procedures. The results show that the fishery is based on the exploitation of two main species (anguilla and grey mullet) and that important variations exist between the two sampled years. The limits to be reached by the working of this fishery are prompted in the scope of a future regulation. |

This study aimed to compare the contamination levels of various organohalogenated compounds in two migratory fish species in the Vilaine River in western France. Organochlorinated pesticides, polychlorinated biphenyls (PCBs), dioxins (polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDDs/Fs)), and polybrominated diphenyl ethers (PBDEs) were analyzed in two diadromous species from the Vilaine estuary, the grey mullet (Liza ramada)-an amphihaline species, and the allis shad (Alosa alosa)-an anadromous species. Fish were collected in spring 2004 and spring 2005, upstream and downstream of the Arzal Dam. PCB contamination varied from 27 to 200 ng g(-1) dry weight (d.w.). PCDDs/Fs, expressed in toxicity equivalent quantity (TEQ) varied from 0.4 to 2.8 pg g(-1)... |
