Estratificación de la flota industrial de buques fresqueros y estimación de los rendimientos OceanDocs
Bertolotti, M.I.; Pagani, A.N.; Hernandez, D.R.; Buono, J.J..
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.

Estratificación y análisis de la eficacia y la eficiencia de la flota costera de pequeña escala perteneciente a la Sociedad de Patrones Pescadores del puerto de Mar del Plata. OceanDocs
Errazti, E.; Hernandez, D.R.; Bertolotti, M.I.; Buono, J.J..
This chapter includes an economic analysis of the small scale fleet of the Mar del Plata harbour, Buenos Aires Province, Argentina. The original study was carried out at the request of the Skippers Fisheries Society to find out the relative efficacy and efficiency of homogeneous groups of associated vessels. Based on the information available, to tune the observed data, assess the relative efficacy and estimate the relative economic efficiency of the fleet, an ad hoc model was designed. Length, gross registered tonnage, engine power and number of crew members were considered and analyzed as structural variables for 1995, 1996 and 1997. No changes in variables for the period were observed so, the efficacy and efficiency analysis was carried out for the year...

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...
