The fishery exploitation of acoupa weakfish off São Paulo coast, southeastern Brazil

The Acoupa weakfish Cynoscion acoupa (Lacepede, 1801) is a large inshore sciaenid of commercial and social importance found along the entire Brazilian coast. In spite of this, there is few information on the species, both in terms of biological aspects and fishery yields, particularly off southeastern Brazil. Within this context, this study aimed to an evaluation of Acoupa weakfish fishery production off Sao Paulo coast (23 degrees 22'-25 degrees 18'S) based on publicly available statistical data collected between 1998 and 2016. Acoupa weakfish fishery in this State takes place on both industrial and artisanal scales, and employs at least 22 different fishing gears. The pair-trawling fishery was the most important Acoupa weakfish producer during the period surveyed, with a sharp decline in the catches from 2007 onward due to the establishment of Marine Protected Areas off Sao Paulo coast, which banned trawling in depths shallower than 26 meters. Acoupa weakfish yields were relatively low in Sao Paulo when compared with other demersal fishes exploited, despite the high retail prices commanded by the species in regional markets and restaurants.
