| In the context of the new European Common Fisheries Policy and in particular the Landing Obligation, this report synthesizes the trials which were carried out between 2014 and 2016 on French bottom trawlers operating in the Celtic Sea and Western Channel, to decrease their discards. All the detail of the experiments and their results are attached in the voluminous appendices. After a state of the art and various workshops organized in partnership between fishermen, equipment manufacturers and scientists, 3 basic devices were selected for the trials, according to the main fisheries: - 100 mm square meshes cylinder - SMC - (in addition to the mandatory 100mm and 120 mm square mesh panels - SMP) with or without scaring floats ; - Extension + codend in... |

| The presence of a herpes-type virus has been demonstrated in various species of marine shellfish (bivalves and gastropoda) throughout different regions of the world (Europe, North and South America, Asia, Australia), and is frequently associated with high mortality levels. Nevertheless, apart from the sanitary monitoring in mollusc farming, very little data is available about the detection of this type of virus in the natural populations of bivalves and about the persistence of such viruses in sea water. Various diagnostic tools have been developed in order to detect the oyster herpes virus (Ostreid herpesvirus, OsHV). The presence of this virus has been looked for by PCR in marine water samples coming from fattening ponds, in order to precise the natural... |

| Des infections à virus de type Herpès sont rapportées chez différentes espèces de mollusques bivalves, à travers le monde. Elles sont associées à de fortes mortalités des larves dans les périodes chaudes de l'année dans des écloseries. Les variations inter-annuelles d'intensité du captage de Crassostrea gigas, et plus particulièrement le déficit de celui-ci en 1998, dans le bassin d'Arcachon, ont conduit à un programme pluriannuel de suivi. Ainsi, l'évolution des populations naturelles de larves d'huître creuse, des deux bassin de captage, Arcachon et Marennes-Oléon, est suivi afin d'expliquer d'éventuelles anomalies du recrutement. Dans ce cadre, la détection du virus de type Herpès sur ces larves du milieu naturel a été effectuée, à partir d'un protocole... |
