在海蜇(Rhopilema esculenta Kishinouye)增殖实践中,人工培育出的螅状幼体需要经常进行抽样观察,倒池换水或移养到自然海区暂养。根据几年来的经验,螅状幼体短时间离水暴露于空气中对其成活率影响不大,但对离水的时间长短与螅状幼体成活率的定量关系尚未做过实验。为给螅状幼体培养管理中制定操作 In the practice of multiplication of Rhinopithecus esculenta Kishinouye, the artificial nudibranch needs frequent sampling observation, changing the water in the inverted pool or holding it in the natural sea. According to the experience of the past few years, the larvae have little effect on the survival rate when exposed to air for a short time. However, the quantitative relationship between the lag time and the survival rate of larvae has not been tested. Formulation for management of otter-like larvae
