Alternative Title
Bycatch from the shrimper and hake specialised fisheries in the Mauritanian waters : Qualitative assessment.
Abstract
Résumé L’analyse des échantillons prélevés sur les captures des crevettiers et merluttiers espagnols opérant dans les eaux mauritaniennes entre 1991 et 1994, a montré que ces pêcheries engendrent beaucoup de prises accessoires. Ces dernières varient entre 87% et 89% pour la pêcherie crevettière et dépassent 64% pour la pêcherie merluttière. Le rapport prises accessoires/capture espèce cible varie donc de 7 :1 à 8 :1 pour les crevettiers et se situerait à environ 2 :1 pour les merluttiers. Les prises accessoires sont constituées principalement de poissons démersaux (représentés essentiellement par les sparidés), de céphalopodes (poulpe, seiches et calmar) et de petits pélagiques. Les poissons démersaux sont largement dominants.
Abstract From 1991 to 1994, samples were from catches on board of spanish shrimpers and hakers operating in the Mauritanian waters. It is shown that bycatch in the shrimp fishery varies between 87% to 89% of total catch for shrimpers and is about 64% for hake fishery. Also, the ratio bycatch/target species varies between 7:1 and 8:1 and is about 2:1 in the shrimp and hake fishery, respectively. Bycatch is composed mainly of demersal fish (represented essentially by the sparidae), cephalopods (common octopus, cuttlefish and European squid) and small pelagics ; démersal fish being dominant component
