Abstract
    The aim of this paper is to summarize bivalve restocking programmes in Chile and its relation to the current Management Areas System (Áreas de Manejo y Explotación de Recursos Bentónicos, AMERB). Primarily, restocking is defined from a point of view of the objective (i.e. to preserve or to conserve) and accordingly the way it is carried out (through management, seeding or mixed). In Chile, the main bivalves for restocking purposes include species of mussels, clams (sensu lato), scallops and oysters, represented by 16 species. At present, some of these species have been identified as important resources for 79 management areas (AMERB) (corresponding to 20 percent of the total areas under current management). It is concluded that bivalve restocking experiences in Chile have been few, unlike other countries. Furthermore, the limited experiences have not progressed from the experimental level. Finally, an algorithm for calculating the resto king of a benthic resource is proposed as applied in the Bay of Ancud case study. It is concluded that the Bay of Ancud would have to be seeded with about 170 million clams to eventually obtain productions, 4-5 years later, equal or superior to the current production levels.
