Avaliação do crescimento de Anomalocardia brasiliana (Gmelin, 1791) na praia de Mangue Seco, litoral Norte do Estado de Pernambuco, Brasil

Abstract

The clam Anomalocardia brasiliana has a great importance economic and social at the development of artisanal fisheries in the north coast of Pernambuco - Brazil, but uncontrolled exploitation of this resource in the region could compromise the stocks. This study aimed to analyze the morphometric relationships of growth of the clam collected from Mangue Seco beach, Igarassu municipality, north coast of Pernambuco. To verify if the morphometric relationships of the shell have non linear regressions were made it between length / width, using the methodology of Gauss Newton. As for analysis between length classes over the month the ANOVA were used followed by Duncan's Test (P< 0,05). The month of July/2009 showed higher average length of 22.76 mm. A. brasiliana has allometric growth between the morphometric measurements of shell growth, indicating that the species has a long and steady growth among width over time.
