Croissance de différents lots de coquille Saint-Jacques Pecten maximus en culture sur le fond dans la Rade de Brest ArchiMer
Buestel, Dominique; Gerard, Andre; Guenole, Annie.
Six batches of king scallop juveniles of different origins and obtained either by collection in their natural habitat (Saint-Brieuc, Scotland, Ireland), or by hatchery production in Brest in 1981, 1982, 1983, have been sown, at a size of 3 cm, in the roadsted of Brest between 1977 and 1983. Their growth, strongly linked to the evolution of the temperature, is well-described by a model, including a sinusoidal modulation, by Von Bertalanffy. The growth of the scallops collected in Saint-Brieuc, Scotland and Ireland, differentiates from that of the individuals from their original area and shows similarities with that of the scallops produced in Brest. Consequently, there must be an adaptation of the growth to the environmental conditions of the roadsted of...

Introduction : Since 1978, new measures to better manage lobster fisheries were implemented in the Celtic Sea within the context of Community regulations. Meshing, in particular, was set at 60mm, but many owners, in order to maintain sufficient leeway vis-à-vis the regulations and to avoid administrative hassles adopted at the outset fish meshing at 70mm, even 80mm. Certain habits aiming to compensate for the losses due to these increases were established: Adoption of better-performing trawls, increase in the secondary catch and enlargement of the fisheries. At the same time, especially because of strong demand from international bodies, OEM and especially EEC, knowledge about the lobster spread and more reliable assessments were achieved, the main problem...

Les rejets dans la pêche artisanale de Manche occidentale ArchiMer
Morizur, Yvon; Pouvreau, Stephane; Guenole, Annie.
Observers were set on board of fishing vessels from North Brittanny ports during one full year (1992-93). This study granted by EC Commission (contract CE/DGXIV-C-1 n° 1992/06) was a first approach for assessing French discards in the western English Channel. It identifies the main species discarded and produces a rough estimate of discard rates and size compositions in each métier targeting fish. The major reasons for variability were explained. Size compositions of catches and discards were provided in order to permit better estimates of the mortality induced by fishing operations. The fixed nets observed were large mesh nets (270 to 360 mm) targeting monkfish and small mesh nets (<200 mm) targeting coastal resources. Netting was found to be more...

Prégrossissement du naissain de coquille Saint-Jacques Pecten maximus (L.) en rade de Brest - Résultats obtenus en 1983 ArchiMer
Buestel, Dominique; Guenole, Annie; Mingant, Christian.
In 1983, the pre-grow-out in the roadsted of Brest of 1.5m king scallop maximU6 post larvae from 1 to 5 mm lead to the production of 250,000 juveniles of a size comprised between 27 and 31 mm. The culture conditions have been particularly unfavourable in June with an infestation by the drilling worm Polydora sp and the starfish Asteria rubens, and in July when important mortalities and a stopping of the growth have been observed as well as the presence in the plankton of large quantities of dinoflagellates (most certainly toxic). Some experiments showed that the sensitivity of the scallops to those different mortality factors is proportional to the size of the farm.
