Desarrollo de un modelo bioeconómico para el manejo integral de un recurso pesquero OceanDocs
Bertolotti, M.I.; Verazay, G.A.; Abal, H.J..
A deterministic single-species bioeconomic model is developed in order to provide an integral fishery management. This model is structured by age, in order to simulate the effects of natural and fishing mortalities, with simple economic assumtions. Fishing mortality is estimated through the fishing effort expressed by fishing hours or by HP per fishing hours. Biological underfishing and overfishing are analyzed from the estimated economic equilibrium for period under study.

Flota pesquera Argentina. Evolucion 1960-1998 con una actualizacion al 2000. OceanDocs
Bertolotti, M.I.; Verazay, G.A.; Pagani, A.N.; Errazti, E.; Buono, J.J..
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...
