The Patagonian fishery resources and the offshore fisheries in the South-West Atlantic
The state of the main fishery resources exploited by the offshore fleets in the South-West Atlantic is examined and some suggestions are made regarding research and management of the offshore fisheries in the region. Common hake (Merluccius hubbsi) is mostly caught in the northern Patagonian shelf and off the River Plate Basin area and the resource seems to be lightly to fully exploited. Southern blue whiting (Micromesistius australis) is mostly caught over the Patagonian Shelf and Slope around the Falkland Islands (Malvinas) and the resource seems to be lightly to moderately exploited. Shortfin squid (Illex argentinus) is mostly caught in the offshore Patagonian Shelf and Slope from the area off the River Plate to the northern part of the Falkland Islands (Malvinas), the abundance and annual catches are highly variable and until 1985 the resource was reasonably exploited but it is likely that the increased fishing effort in 1986 may have driven the stock to an overfishing situation. A variable fishing effort policy is suggested to manage this fishery in view of the great fluctuations in recruitment strength. It seems that the common squid (Loligo sp.) stock is fully exploited with a high probability of becoming overexploited. Some general aspects regarding the state of other fish resources and of other possible effects of these offshore fisheries are also examined. The Patagonian fishery resources and the...
