Abstract(s)
Foram realizadas 9 campanhas de pesca ao longo da costa sul portuguesa entre 1991 e 1995, com o objectivo de estudar as comunidades de moluscos bivalves que ocorrem entre as batimétricas dos 3 aos 25m, com especial relevo para as espécies exploradas {Spisula solida, Ensis siliqua, Vénus siriatida e Donax trunculus).
Nine surveys were carried out along the south coast of Portugal from 1991 to 1995, in order to study the population dynamics and distributions of bivalve molluscs that occur between 0 and 25 meters of depth, with particular emphasis on commercially important species (Spisula solida, Ensis siliqua, Vénus striatula and Donax trunculus).
