本文基于缢蛏Sinonovacula constricta浮游幼虫适宜温、盐度和饵料种类的研究,通过几种单因子(饵科密度、幼虫密度和光照等)和结合因子对缢蛏浮游幼虫生长和存活影响的试验,摸索出培养浮游幼虫最适生态条件:饵料密度开始2d为1～2.5万个/mL,2d后增加至5～10万个/mL,幼虫放养密度为5～10个/mL:光照强度应控制在3000lx左右。此条件下单位水体出稚贝量稳定在200～400万粒/m~3,存活率在80％以上。 Based on the studies on the optimum temperature, salinity and food species of plankton larvae in Sinonovacula constricta, this article explores the effects of several single factors (such as bait density, larval density, light intensity, etc.) on the growth and survival of larvae The optimum ecological conditions for the culture of planktonic larvae were as follows: the density of the diet began to be 1-2000 / mL for 2 days and increased to 5-10-100 / mL after 2 days, and the stocking density of larvae was 5-10 / mL: the light intensity should be controlled at 3000lx about. Under this condition, the amount of juvenile water per unit volume stabilized at 200-4 million / m 3 and the survival rate was above 80%.
