Abstract

The amount of dolphin-fish caught in south of Brazil during summer increased since 2001 due to demand of exportation companies based in Itajaí­­, in the state of Santa Catarina. Most of catches was landed by semi-industrial boats of Itaipava (Espí­­rito Santo state) that fishes with hooks and lines. This work presents descriptions of catches, fishing effort and CPUEs, so as a discussion about the strategy adopted by the fishermen. Production peaked in 2003, when 711 ton had being landed. CPUE declined from 585 kg/1,000 hooks in 2001 to 184 kg/1,000 hooks in 2005. Fishing strategy adopted by fishermen suggests a high degree of specialization of the fleet.
