Study on morphology and histology of abalone deformed trochophora;
九孔鲍担轮幼虫畸形的形态与组织学研究
Based on the morphological change, early development can be divided into 2 stages: embryonic development (including cleavage, blastula, gastrula, egg-trochophora and egg-veliger) and larval development (including weaning stage, big veliger, settlement stage and creeping larvae).
在水温27～29℃、气温27～31℃和海水盐度为16的环境条件下人工孵化瘤背石磺的卵块,根据早期发育的形态变化将其划分为胚胎发育(包括卵裂期、囊胚期、原肠期、卵内担轮幼虫、卵内面盘幼虫)和幼虫发育(包括开口期、大面盘幼虫、附着期、匍匐幼虫)两个阶段。
