    Description: Patagonian scallop (Zygochlamys patagonica King Broderip, 1832): A new fishery in the Argentine continental shelf. We present preliminary information on a new fishery of patagonian scallop (Zygochlamys patagonica King Broderip, 1832) in the Argentine Continental Shelf. A research program was conducted jointly by INIDEP and a fishing company during 1995 with the F/V Erin Bruce. The vessel, fishing equipment and processing on board are described. A total of 7235 fishing tows were performed during 246 days at sea. Seven new beds were located between 38º 50' S and 42º 30' S, along the 100-m isobath. Beds are discrete. Differences in the size structure by bed suggest that recruitment consists of sporadic pulses. Proportion of scallops and invertebrate by-catch also varies among bed. According to average CPUE, which ranges from 291 to 4,927 kg of commercial size scallops per towing hour, beds present different commercial interest. Available information indicates that a commercial fishery of the patagonian scallop is viable. We emphasize the continuation of studies in order to manage and develop the patagonian scallop fishery in Argentina.

    Description: The faunistic composition of invertebrate by-catch associated with the Patagonian scallop Zygochlamys patagonica fishery before its development were studied. Analyzed material was sampled from catches performed in different beds with the F/V Erin Bruce during 1995, all of them in undisturbed areas, in the Argentine continental shelf. Macrofaunal species were identified, weighted and percentages of presence estimated. By-catch invertebrate species were determined for every bed, mainly invertebrates without present commercial value. This baseline information is considered a useful tool to detect structural changes in the benthic communities in relation to the conservation of possible substrates of recruitment of this resource and to estimate the evolution of the communities during the development of the fishery.

    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.
