Stratégie d'exploitation des zones de pêche d'un chalutier hauturier du Guilvinec

The Bigouden region's fishing is significant by the tonnage landed, the quality of the production and high sales price. That makes Guilvinec "an ideal laboratory for analysing the fish business in all its complexity, from the catch to marketing". The fishermen of the Guilvinec district are spread out in 3 ports: Guilvinec, Loctudy, and Saint Guénolé. Each port has its speciality (example: Guilvinec's speciality is monkfish). Each fleet is composed of dinghies, coastal trawls, seafaring fish trawls, and seafaring crayfish trawls. The subject chosen for this master's theses is the study of the fishing strategy of a seafaring ship, the Kerflous. This work was difficult because it reached into the sphere of the professional secret. The Kerflous works at the boundary of sectors 7H1, 7H2, E1, BA1 and BA2 of the CIEM delimitation. The choice of fishing sectors by the skipper is made based on many technical, sociological, and economic factors. This paper introduces the methodology of the survey, factors influencing the choice of fishing areas and finally the fishing areas, their exploitation and fishing tactics from 1971 to 1985.
