Biologia reprodutiva daReproductive biology of Anomalocardia brasiliana (Gmelin, 1791) in the north coast of Pernambuco, Brazil ABSTRACTThe clam Anomalocardia brasiliana presents great economic and social importance in the artisan fishing of the north coast of Pernambuco, Brazil. This study aimed to examine the aspects related to the reproductive biology of the natural stock of A. brasiliana in Mangue Seco beach, Municipality of Igarassu, north coast of Pernambuco, Brazil. The reproductive biology of the species was monthly monitored for ten months by histological characterization of the gonadal development, yield (condition index) and sex ratio calculation. The yield and histology analysis results indicated that the species has the potential to reproduce continuously during the study period. These results may be used as a basis for establishing future fisheries management programs and for the development of clam aquaculture in the region.
