Occurrence of ovigerous females of Callinectes bocourti A. Milne-Edwards, 1879 (Decapoda: Portunidae) on the Amazon Continental Shelf
Abstract The family Portunidae comprises a diverse group of crabs, with 336 described species. Although they are easily collected and widely distributed in coastal regions, the life history of Callinectes bocourti remains poorly understood.

| Summary: | Abstract The family Portunidae comprises a diverse group of crabs, with 336 described species. Although they are easily collected and widely distributed in coastal regions, the life history of Callinectes bocourti remains poorly understood. This species is abundant in Amazon estuaries; however, ovigerous females have never been found throughout the various studies carried out in the region, which compromises the understanding of its reproductive cycle. We investigated the presence of C. bocourti ovigerous females in the Amazon Continental Shelf (ACS), Brazil, to confirm the migration of these females to areas outside the oligohaline estuary where the population is abundant. The specimens were captured as bycatch during industrial shrimp fishing on the Brazilian North Coast between February and March 2016. Twelve individuals of C. bocourti were found: three males, five adult females, and three ovigerous females, which is the first record of their occurrence on the ACS. This information can help manage this resource, as the species is exploited for commercial and subsistence means in estuarine fishing communities in the Amazon coastal zone. |
