四、采苗海湾扇贝眼点幼虫的壳长范围为150—220微米,幼虫群体出现眼点幼虫时的平均壳长一般为170—190微米。眼点幼虫出现后,立即倒池清涮池底,投放采苗器采苗,或将幼虫移到另外的池采苗。必要时可根据幼虫的实际密度进行并池或扩池。如培育池较多且幼虫发育较整齐时,亦可根据预计的眼点幼虫出现日期对部分池提前倒池。倒池时,注意防止幼虫流失、干露或在网箱中密度过大。
Fourth, seedlings bay scallop eyes larvae shell length range of 150-220 microns, the larvae appear when the average eye shell larvae shell length is generally 170-190 microns. After the emergence of eye larvae, pour the pool immediately rinse the bottom, put seedlings pick mining, or larvae move to another pool mining seedlings. If necessary, according to the actual density of larvae and pond or pool expansion. For example, if there are many nursery ponds and the larvae develop more neatly, some ponds may also be poured into the pond in advance according to the expected date of occurrence of the eye-spot larvae. When pouring pool, pay attention to prevent larvae loss, dry dew or excessive density in the cages.
