Carcinofauna acompanhante da pesca da lagosta na plataforma continental amazônica, Amazônia, Brasil.

Abstract

In the northern coast of Brazil, the commercial lobster fishing, began in the 1990s, being well characterized by the presence of bycatch fauna associated with this activity. Based on this, the objective of this work was to describe the taxonomic composition of crustacean species collected as bycatch fauna of fishery of the spiny lobster on the Amazonian Continental Shelf. The species were collected during the fishing activity in the year 2019, between the depths of 74 and 98. After being collected, the individuals were identified to the species level, sexing and biometrics of each stored specimen were performed, and later fixed in alcohol and listed in the Carcinological Collection of the Crustacean Laboratory of the National Center for Research and Conservation of Marine Biodiversity in the North (CEPNOR) / Federal Rural University of the Amazon (UFRA). As characterization of the fishing activity in the region, the occurrence of 13 lobster species were reviewed in literature, which in this work were indicated the conservation status and comments on the biology of species along the Brazilian coast. From the point of view of the accompanying fauna, 17 species of crabs were analyzed, the specie Macrocoeloma concavum (Miers, 1886), have been recorded for the first time for the region, and the others occurring in the Amazon Great Barrier Reef. This work brings new perspectives for the conservation of lobster species in the region, aiming at the knowledge of this biodiversity, in addition to the survey of decapod species accompanying the fishing activity and the knowledge of this fauna for the área, within the survey of the real biodiversity of crustaceans in the region.
