Los desembarques argentinos de merluza (Merluccius hubbsi) entre 1987 y 1997 OceanDocs
Irusta, G.; Bezzi, S.I.; Simonazzi, M.A.; Castrucci, R..
The evolution of argentine landings, characteristics of trawl fleets, principal ports, landings per fleet and management unit (north and south of 41°S), areas and fishing seasons are described. Main results show a continuous increase of argentine hake landings as of 1987. Freezers, that operated in the Patagonian zone along the whole year, was the fleet that most contributed to said increase while the ice chilling fleet maintained its level of landings in the period considered. During the second and third quarter of 1996 and 1997, in the north management unit, the fleet fished in the argentine sector of the Common Fishing Zone and north of 41°S. During 1996, in the south management unit, the main fishing zones for both fleets were northeast of Escondida...

Estratificación y estimación de los rendimientos de la flota de buques procesadores congeladores arrastreros. OceanDocs
Bertolotti, M.I.; Hernandez, D.R.; Pagani, A.N.; Castañeda, M.F..
In order to better understand the behaviour of the trawler processing freezer fleet in the Argentine Sea, an analysis of yields and structural characteristics for the 1989-98 period was carried out. The relationship between structural variables and yield expressed in kilos per day was explained with a simplified asymptotic model. The fleet was divided into four homogeneous strata. Common hake is the target of stratum I and stratum II which are deeply affected by overfishing of the species. As of 1993, in stratum III, common hake was replaced by other pelagic and demersal species, mainly hoki. In fleet stratum IV southern blue whiting and hoki were caught. Catches of the latter increased during the last three years.
