Operational analysis of two industrial fleet in the Chilean hake (Merluccius gayi gayi) fishery in the southern-central region of Chile. Investig. mar. [online]. 2005, vol.33, n.2, pp.167-181.

This work aims at analysing the operation of two industrial fishing fleets (company A and company B) which works on the Chilean hake (Meluccis gayi gayi) fishery in the southern-central region of Chile. For this reason, it was used the historical information of the fleet operation from the southern-central region from 1998 to 2002. The fishing grounds were assessed according to effectiveness indicators, unit cost, profitability and utility. The vessels were selected according to indicators of operational efficiency. These outcomes were contrasted with the fishing grounds and vessels employed by the companies during the study period. The most appropriate fishing ground was determined according to the efficiency indicators of 13 fishing grounds of the southern-central region. It must be said that both companies have adequately decided over the fishing ground selection, as they most frequently consider the fishing ground located between Tomé to the West (fishing ground 9), Tomé to the East (fishing ground 8) and southwards Punta Lavapié (fishing ground 10), zones with the best efficiency indicators. With regard to the selection of the best vessel, a ranking analysis of the vessels is carried out for each company by means of the analysis of the anomalies of the efficiency indicators. For the fishing ground 9, this study suggests that company A must operate with the fishing vessel PAMa3 and company B with PAMb4. Nevertheless, in the fishing zone 10, company A must use PAMa5 and not PAMa3 (which is historically being used), and company B has to continue operating with PAMb1 and PAMb2, as it has been done for the study period
