本文报道了有底沙与无底沙培育方法对泥东风螺( Babylonia Lutosa)稚螺生长与存活影响的实验结果。以牡蛎为饵料，实验设计3×1042、5×104和7×104 ind/m2三个密度梯度，采用有底沙与无底沙两种方法培育刚变态的泥东风螺稚螺。经35 d培育，有底沙组稚螺壳高、体重的生长速度和存活率都高于无底沙组，壳高生长速度差异显著( P <0．05)。而两种培育方法不同的密度培育结果，密度7×104 ind/m2与3×104 ind/m2和5×104 ind/m2实验组稚螺壳高生长速度差异显著(P<0．05)，而3×104 ind/m2与5×104 ind/m2实验组壳高生长速度差异不显著( P>0．05)。随着稚螺的生长其潜沙行为越明显，说明有沙培育更符合其具有的潜埋栖息习性，有利其生长和存活。

This paper reported the experimental results on the growth and survival of juvenile Babylonia Luto-sa 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 ex-perimental 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 different ( P>0. 05 ) . The behavior of diving into sand was obvious with the growth of juvenile Babylonia Lu-tosa which indicated that they had a habit of inhabiting sand with better growth and survival.
