In the context of increasing demand for environmental recovery, aquatic systems may face the challenge of evolving under oligotrophication. This is the case in Mediterranean lagoons, in particular the shellfish-farmed Thau lagoon in France, where we studied recruitment of the Pacific oyster Crassostrea gigas. Oyster spat and environmental parameters were monitored at several sampling sites for 3 yr (2012 to 2014) using an original method with a temporal overlap deployment of collectors to study pre- and post-settlement processes and to identify the best conditions for recruitment. Contrary to the ‘no Pacific oyster reproduction’ paradigm in Mediterranean lagoons, our study showed that recruitment of this introduced species is possible in the Thau lagoon at... |

Since spat mortality events that were firstly detected in 2008, Mediterranean shellfish industry seeks to exploit the Pacific oyster spat from lagoon natural recruitment. The CRCM, Cepralmar and Ifremer developed accordingly a research project named PRONAMED Phase 1 and 2 - 2010-2014, in order to define the economic potential of spatfall and improve knowledge of the reproductive cycle of Crassostrea gigas in this specific environmental context. The results of the past three year‘s study (2012, 2013, 2014) showed that broodstock have the ability to provide larvae after sexual maturation and spawning. A coincidence was noted between moon phase (new and full moon) and spawnings with an amplifying effect of storms on the intensity of spawning (Ubertini et al.... |

L'utilisation de petits maillages pour le chalutage crevettier engendre la destruction de poissons immatures d'espèces commercialisables. Depuis plusieurs années, organismes de recherche et professionnels de la pêche s'efforcent de trouver une solution à ce problème. Parmi eux, Monsieur ASSELIN, pêcheur du Hourdel en Baie de Somme, a élaboré un système sélectif permettant l'évacuation des poissons durant la pêche. Grâce à l'amabilité de Monsieur ASSELIN et de son fils, nous avons pu relever toutes les caractéristiques d'un de ces chaluts et participer à une marée sur un bateau utilisant ce type d'engin. |
