Crustaceos decapodos de la captura de arrastre de camarón en la plataforma continental de Chiapas

Abstract

Mexico has the largest ocean coverage area in the eastern Pacific (5,800 km). In the area, fishing is carried out by various types of fleets, which focus on the capture of groups of specific organisms, with shrimp trawling being one of the most important and harmful to marine biota, due to the volumes of accompanying fauna (FAC) that are generated. The FAC is the portion of the catch that accompanies the target catch, including fish and a great diversity of marine invertebrates. The objective of this study was to know the fauna of decapod crustaceans in shrimp trawling on the Chiapas continental shelf. Monthly samplings were carried out during the fishing period (January - March 2018, October - December 2018 - February 2019). The samples for the analysis were obtained from the FAC generated from the shrimp trawl fishery, landed in Puerto Chiapas. 156 organisms belonging to 16 species, 13 genera and 8 families were collected. According to the samples analyzed, the genera with the highest abundance are Callinectes with 13%, followed by shrimp of the genus Rimapenaeus and Penaeus with 13% respectively, which together represented 39% of the decapod crustaceans obtained from the FAC.
