彩虹明樱蛤Moerella iridescens隶属双壳纲樱蛤科的软体动物,是浙江沿海传统的小型经济贝类。自1988年以来,我们对该蛤作了一些基础生物学方面的观察研究工作,在人工育苗试验中,我们注意到了培养该蛤浮游幼虫合理密度的问题,旨为今后的人工育苗积累必要的基础资料。在双壳类的人工育苗过程中,浮游幼虫培养密度的高低,直接影响着单位水体的出苗量,且与幼虫的成活率、附着率、生长速度等有一定的关系。浮游幼虫培养密度过高,会引起大
Rainbow cherry clams Moerella iridescens belonging to the family Bivalvia cherry clam molluscs, Zhejiang is a traditional small-scale economic shellfish. Since 1988, we have made some observations on the basic biology of this clam. In the artificial breeding experiment, we noticed the reasonable density for culturing the clam larvae, so as to accumulate the necessary foundation for future artificial breeding. data. In the process of artificial breeding of bivalves, the density of planktonic larvae culture has a direct impact on the emergence of the unit water, and has certain relationship with the survival rate, attachment rate and growth rate of larvae. The density of planktonic larvae is too high to cause largeness
