DONNÉES POUR L'APPLICATION DES MODELES DE PRODUCTION A L'ÉTUDE D'UNE POPULATION DE VENERUPIS DECUSSATA (L.) EXPLOITÉE DANS LA BAlE DE SANTANDER (NORD DE L'ESPAGNE)

Abstract

The population studied in this paper is isolated, without interaction with any other population of fue same species. The fact that 85% of the fishermen exploiting fue population come from the same place (Pedreña, a village in the south of Santander Bay) makes fue control of catch and effort easier. Mter a description of the area studied fue method used in fue study of the stock of VeneruPis decussata (L.) is described together with difficulties associated with its practical application. Trials of fue application of production models were made with effort data obtained using the unit man per hour. Calculations have algo been done to study the distribution of sizes and ages of fue catches.
