Growth rates of the giant clam Tridacna maxima (R?ding, 1798) reared in cages in the Egyptian Red Sea

摘要

The giant clam,Tridacna maximawere reared in cages in the sea; measurements of the shell's length, height, width and buoyant weight were taken under water to compare the growth rates of different size groups ofT. maxima. The results showed that the specific growth rates were significantly high in the smallest size group and decreased with increasing clam size (P?
