Anomalocardia flexuosa is a bivalve present in the Brazilian coast wich has a great importance as a source of income and subsistence for traditional communities at the coastal zone. The present study aimed to obtain information that can be applied in the sustainable exploitation of this specie. We collected 134 specimens to make probable comparisons with others populations from different regions. This analysis used as a parameter the weight-lenght relationship of the species in 3 different areas of a hypersaline estuary, in the Apodi-Mossoró River, Rio Grande do Norte. From the analysis it was possible to verify that in all areas, the individuals did not present isometric growth, indicating that the variables weight and length do not grow proportionally. Furthermore, it was not possible to observe a big difference in length and weight variables between the areas, which seems to demonstrate that the environmental differences in these areas, may not influence the growth pattern of A. flexuosa. Therefore, at the three sampled, the individuals presented positive allometry, corresponding to the already known pattern for this specie.
