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.

In order to increase knowledge about the ice chilling fleet and to explain the relationship between structural variables and yields, a simplified model was developed. The fleet was classified in three homogeneous strata. Stratum I includes the smallest ships, with a catch composition equal to that of the large coastal fishing vessels. The stratum yields decreased in 1997 and 1998. Strata II and III have common hake as the main target of catches. Yields of those strata showed a continuous decrease as of 1994/1995. Therefore, the species was replaced by other fish originally caught by other fleets. These two last strata are more vulnerable to overfishing of traditional coastal and demersal fisheries.

The analysis of the Argentine fishing fleet (SW Atlantic) evolution as of 1960 allows to explain the major causes of expansion, the crisis in the fisheries and the structural changes of the fleet during the 90's. Different fleet classification criteria focused on fishing capacity, fish landing composition, yields and productivity indices are described. The expansion cycles were associated to the incorporation of fishing vessels, while the 1960-1989 crisis originated in domestic and international economic crisis and changes in the strategy pattern of the fishing countries. The latter was related to overfishing of traditional coastal and demersal fisheries and to the full exploitation of resources such as squid, blue whiting and toothfish incorporated to the...
