Síntesis del estado de las pesquerías marítimas argentinas y de la Cuenca del Plata. Años 1997-1998, con la actualización de 1999

Abstract

In several chapters, the fisheries resources of the Argentine Sea are analyzed according to the degree of fishing exploitation and considering the stocks in a state of: 1) overfishing (hake Merluccius hubbssi), some species of coastal fishes (Micropogonias furnieri) and austral demersal (Micromesistius australis); 2) exploitation close to the maximum sustainable levels (several species such as Genypterus blacodes and Mustelus schmitti) and of bivalves (Zygochlamys patagonica), shrimp (Pleoticus muelleri), squid (Illex argentinus); 3) feasibility of development (some species of pelagic fishes (Engraulis anchoita and Scomber japonicus) and demersal-pelagic (Macruronus magellanicus), among others, and 4) special cases and perspectives for species that require research and monitoring (some crustaceans such as king crab Lithodes santolla) from the Beagle Channel, elasmobranchs (Squalus acanthias and Dipturus chilensis), bony fishes (Patagonothothen ramsayii) and cephalopoda (Loligo spp.). Progress in the development of fishing gear selectivity and in marine culture and a brief outline on oceanographic conditions and occurrence of toxic red tides recorded are also presented. The status of resources and fisheries in the main rivers (Parana, Uruguay and de la Plata) of the del Plata Basin are wholy described.
