Las pesquerías de crustáceos decápodos en el litoral de la República Argentina

Abstract

The existent information on the fisheries of Decapod Crustaceans on the continental shelf and slope off Argentina (South West Atlantic Ocean) is resumed and analysed. At the present five species of Decapoda have commercial value two anomurans: Lithodes santolla (Southern king crab) and Paralomis granulosa (False king crab), two peneids: Pleoticus muelleri (Argentine red shrimp) and Artemesia longinaris (Argentine stiletto shrimp) and one brachyuran Ovalipes trimaculatus (swimming crab). Scientific cruises and expeditions were performed to different regions of the sea, where these crustaceans are exploited. It was possible to obtain important biological and fishery informations on these species, in relations to areas and seasons of the reproduction, growth, recruiment, fishery concentration, etc, which allowed to recommend management of these resources. The most importan one is the patagonian stock of the P. muelleri. Since 1980, landing of this shrimp have increased significantly and in some years, reached 25.000 mt. This represents about 100 millon US dollars, as the value for exportation.
