Description:
Fisheries of the mussel Mytilus edulis platensis, the tehuelche scallop Aequipecten tehuelchus and Patagonian scallop Zygochlamys patagonica are described. Information about catches of purple clam Amiantis purpurata in San Matias Gulf, mussel Aulacomya ater ater and hard shell clam Ameghinomya antiqua in San José Gulf is also presented. Regarding mytilus fishery, it is observed that the main catches were situated in Faro Querandí and Quequén beds (Buenos Aires Province, Argentina), where high densities occured in an area between 35 and 60 m depths. Those beds were exploited until the production was no more commercially interesting. The tehuelche scallop is a very well known resource from the Argentine Sea and its fisheries from San Matías and San José Gulfs was widely registered. However, both fisheries were ended due to low densities and declination of the stocks, during 1995 and 1996, respectively. Regarding the Patagonian scallop, during December 1994, the national government authorized the American F/V Erin Bruce to carry out a joint research program during a year. As a result of this experimental program, new and dense beds were found and regulation of extraction were established. In 1996, four fisheries vessels with equipment to process the mussels were authorized to fish. It was the beginning, of a new fishing in Argentina.
