- Crustacean fauna (Stomatopoda: Decapoda) associated with the deepwater fishery of Heterocarpus vicarius (Decapoda: Pandalidae) along the Pacific coast of Costa Rica Silvia Echeverría-Sáenz Ingo S. Wehrtmann Biología bycatch Central America deepwater fishery Heterocarpus vicarius eastern tropical Pacific Commercial bottom trawling is a successful and commonly used method to catch marine shrimps.However, the shrimp fishing gears are poorly selective, and in addition to the target species they catch and retainlarge quantities of non-target species (bycatch). This study presents data concerning species composition anddepth distribution of the crustacean fauna (stomatopods and decapods) associated with Heterocarpus vicariuscatches from Pacific Costa Rica. A total of 74 samples (three to five 20 min-tows each month) were takenbetween January 2004 and December 2005 with commercial shrimp trawlers at depths varying between 192and 350 m. In all depth ranges analyzed, total catch of crustaceans was significantly higher than that of fishes.A total of 28 decapods and two stomatopod species were identified. In comparison to other bycatch compositionof comparable fisheries in Latin America, the crustacean fauna of the H. vicarius fishery in Costa Rica ishighly diverse. Most common species were Solenocera agassizii (Solenoceridae), Squilla biformis (Squillidae),Plesionika trispinus (Pandalidae), and Pleuroncodes sp. (Galatheidae), reaching total catch percentages of57.2 %, 81.5 %, 91.8 %, and 99.6 % of individual catches, respectively. The results presented herein maycontribute to the development of responsible management strategies for the deepwater fisheries in Costa Ricaand Central America. Rev. Biol.
