采用紫外线海水培育、充气海水培育、流水孵化培育、流水孵化培育中试 4种不同方法进行皱纹盘鲍(Haliotisdiscushannai)幼虫孵化培育 ,并与常规孵化技术对照 ,结果表明 :紫外线海水孵化培育组幼虫 48h面盘与壳分离死亡 ;充气流水培育组幼虫发育畸形 ,48h下沉死亡 ;流水培育组幼虫孵化率为 6 9 7% ,流水培育中试组幼虫孵化率达 75 8% ,而对照组孵化率仅为 2 3 5 %。流水孵化培育不仅提高了孵化率 ,而且稳定性较高 ,同时节省大量劳动力。
The hatching of Haliotis discus hannai larvae was carried out by four different methods: ultraviolet seawater cultivation, aerated seawater cultivation, running water hatching cultivation and running water hatching cultivation pilot test. The results showed that: The faceplate and the shell were separated and died. The larvae developed deformity in inflatable water-flow group and died down after 48h. The hatching rate of larvae in stream-cultivating group was 69.7%, and the hatching rate in larva of flow-cultivating group was 75.8% Only 23 5%. Incubation incubation not only increases hatchability, but also higher stability, while saving a lot of labor.
