| The Pelgas16 acoustic survey has been carried out with very good weather conditions (regular low wind, medium temperatures) for the whole area, from the South of the bay of Biscay to the west of Brittany. The help of commercial vessels (two pairs of pelagic trawlers and a single one) during 18 days provided about 120 valid identification hauls instead of about 60 before 2007 when Thalassa was alone to identify echotraces. Their participation increased the precision of identification of echoes and some double hauls permitted to confirm that results provided by the two types of vessels (R/V and Fishing boats) were comparable and usable for biomass estimate purposes. These commercial vessels participated to the PELGAS survey in a very good spirit of... |

| Persistent organic pollutants (POPs), such as PCBs (polychlorinated biphenyls) and PBDEs (polybrominated diphenyl ethers), are lipophilic and tend to bioaccumulate in cellular membranes and fat. The accumulation of lipids in oocytes during vitellogenesis, and subsequently in the eggs, favors the accumulation of POPs, and may affect the development of embryos. The effects of dietary exposure to POPs in Common sole Solea solea were evaluated on early life stages (ELS): the survival of sole embryos and features of embryonic development were assessed until hatching endpoint and compared to that of the control. No embryonic development was observed in PBDE eggs while hatching occurred in both control and PCB groups. In addition, several developmental... |
