Alternative Title
Pink lobster Palinurus mauritanicus of Mauritania: biology, fishing and status of stock
Abstract
Résumé : La biologie de la langouste rose des côtes mauritaniennes est aujourd’hui bien connue. Nous avons cependant rappelé les traits marquants. Sur le plan de la pêche, de 1963 à 1988, le stock de la langouste rose a connu trois phases d’exploitation. Après une phase de surexploitation entre 1963 et 1970-1971, le stock de langouste rose de Mauritanie a pu se reconstituer grâce à une réduction importante du nombre de langoustiers. Ceci c’est traduit à partir de 1971 par une augmentation sensible des captures et aussi de la PUE. Mais le dédoublement du nombre de ces derniers en 1987 et 1988 a fait chuter les P.U.E de 50% ce qui est un signe d’effondrement du stock à nouveau.
Abstract : Biology of Mauritanian pink lobster is known. However we presented some important aspects of specie’s biology. On fisherie’s plan, between 1963 and 1988, the stock of Mauritanian pink lobster went through three phases of exploitation. Like this, after an over exploitation phase between 1963 and 1970-1971. The stock of the pink lobster of Mauritania was reconstituted little by little owing to an important reduction enabled a significant increase in the number of catches and the C.P.U.E. But doubling in the number of beats in 1987 and 1988 reduced the C.P.U.E. by 50%, which again contributed to the breaking down of stock.
