Abstract: This paper reported the experimental results on the growth and survival of juvenile Babylonia Lutosa cultivated by two different nurtured methods， which one was with sand in container bottom， and the other one was with non - sand in that. In our experiment， we designed three different density groups of 30 000 ind /m2，50 000 ind/m2 and 70 000 ind/m2 which fed by oyster. The results showed that the shell height，weight and survival of juvenile Babylonia Lutosa in sand experimental group were higher than those in non - sand experimental group after 35 d. Ccopared among three densities， the results cultured by two methods indicated that the shell height growth of 70 000 ind/m2 group were significant different from those of other groups (P<0.05) But the shell heigtt growth between 30 000 ind/m2 group and 50 000 ind/m2 group was not significant difference (P>0.05). The behavior of diving into sand was obvious with the growth oi juvenile Babylonia Lutosa which indicated that they had a habit oi inhabiting sand with better growth and survival.
