Approche de la dynamique de stocks accessoires ArchiMer
Moguedet, Philippe.
For a few years now, the landings from the Lorient's industrial fleet have been continually increasing (32,000 tons in 1980, 56,000 tons in 1985). This fleet practices a multispecific exploitation of the international fishery of the west and north of Scotland. The rock salmon (Pollachius virens) is the fleets' target species, its catches of other gadidae are considered secondary. Two of the catches, those of the blue ling (Molva dypterygia) and the ling (Molva molva) have been advancing since the beginning of the decade and in 1985 represented 21% of the total amount in quantity and value landed by the industrial fleet. The objective of this study is to asses the status of these ling resources and examine whether their exploitation can, in the short term,...

The general study, scheduled from 1984 to 1986, aims at providing a judgement about the fisheries in the Celtic Sea. This area has been chosen because it is frequented by EEC vessels with, for the time being, a large majority of French vessels. Activities there are easier to monitor than anywhere else as coastal fisheries are little developed in the area. The final product will consist of a certain number of hypotheses about the planning strategies that could be implemented in the Celtic Sea. The main idea is, firstly, to conduct analytical studies, stock by stock, in order then, to synthesize them into a model integrating the interactions between fleets in relation to their target species. A bio-economical model, deriving from the latter, will enable the...
