The Gulf has very tiled sea beds, and the surface areas of habitats suitable for ormer populations are rather reduced (1.56km2). Three zones have ormer densities of interest from the point of view of profitability, Brannec, lrus and Creizig. But since their surface area is not great, the exploitable biomass, that corresponding to individuals of a size greater than 80mm (legal catch size), is average. These three zones would be exploitable but following a limited fishing effort. The sectors of Ile aux moines and Jument and Henn Tenn show average to low densities and are not therefore exploitable in a profitable way. Finally, Gavrinis and le Logeo have revealed low densities of ormers, this could be due to an intensive illegal exploitation. In fact, many...

La mytiliculture en Hollande et en Espagne
Provedor de dados: 5
Autores: Antona, Martine; Paquotte, Philippe.
This article is the second part of an analysis of mussel-farming sectors in France, Holland and Spain. The first part, devoted to France, addressed the national offering's stresses of adapting to changes in the mussel market. From the viewpoint of questions raised within the profession while preparing the French mussel-farming sector for the regulatory and economic environment of 1992, Spain and Holland offer benchmarks in terms of structuring the offer and planning markets. This article presents the mussel-farming business in Spain and Holland from these two angles.

Etudes des activites de peche dans le golfe du Morbihan, peche professionnelle
Provedor de dados: 5
Autores: Peronnet, Isabelle; Talidec, Catherine; Daures, Fabienne.
The objective of the study is to improve knowledge of coastal fishing activity in the halieutic and economic spheres. It consists of three sections: On-board professional fishing, professional shellfish gathering, and leisure fishing, this last one being the subject of an independent report (Lesueur and Drouot). The methodology applied is based on implementation of specific surveys about the ships that frequented the Gulf of Morbihan in 2001. The emphasis was placed on identifying the occupations practiced in this zone, on describing these activities and their intensity as well as on analysing the economic performance of these fleets. The management methods, regulation of shellfish gathering on listed sites as well as their impacts on the environment are...
