Growth and mortality were estimated in the culture of Manila seed clams Ruditapes philippinarum (Adamsampersand Reeve, 1850) from a hatchery. The culture was been carried out in two 1.50 m x 26.00 m plots, located between higher water (HLW) and lower low water (LLW) in an intertidal zone, at densities from 1 000 to 1 500 indiv/m².
