A new approach to control and manage the Argentine fishery for Patagonian toothfish (Dissostichus eleginoides)

摘要

The Patagonian toothfish (Dissostichus eleginoides) exploited by the Argentine fleet is distributed in shelf and slope waters between 37 °S and 56 °S. Argentine catches are taken using two different fishing gears: bottom trawl and longline. Longliners mainly catch adult fish, while bottom trawlers often catch more juveniles, due to difficulties in operating in deeper waters or on bottoms less suitable for trawling. It has been observed that size selectivity is more dependent on the depth of fishing than on the fishing gear (Prenski and Almeyda 2000).
