Alternative Title
Global approach of stock assessment of Pink shrimp (Parapenaeus longirostris) in northern region of Tunisia
Abstract
Des donnees de production et d'effort de peche ont ete recueillies aupres des services de la Direction Generale de la Peche et de l'Aquaculture (DGPA). Ces donnees s'etendent sur onze ans (1987-1997). L'unite d'effort selectionnee est le produit du nombre de jours en mer et de la jauge brute (JM*JB). L'application des modeles de production (Fox et Shaefer) a ces donnees montre que les stocks de chevrette actuellement exploites sont proches de leur optimum d'exploitation. Ainsi, un leger accroissement d'effort pourrait etre envisage mais le developpement de la peche de la chevrette passe, inevitablement, par l'exploration de nouvelles zones de peche
Production and fishing effort data have been collected at services of the Tunisian Fisheries and Aquaculture General Direction DGPA. These data concern eleven years (1987-1997). The selected effort unit is the fishing days and gauge tonnage (FD*GT), which combine fishing days and stored capacity of boat. The application of production models (Fox and Shaefer) to these data shows that stocks of deep-water pink-shrimps P. longirostris currently exploited are close to their optimum exploitation. Thus, a light increase of effort should be envisaged but the development of the fishing stocks of this species must be passing by the exploration of new fishing zones
