为探索方斑东风螺的人工育苗技术 ,进行了室内人工育苗试验。采用降温干运法将亲螺从湛江水产学院运回试验基地 ,控制培育池水深 2 5～ 3 0cm ,海水比重 1 .0 1 7,水温 2 8～ 3 0℃ ,保持充气和流水刺激 ,投喂新鲜的蟹肉和鱼肉。收集亲螺产出的卵囊 ,冲洗消毒后放入孵化池孵化。培育单细胞藻类作东风螺幼体的饵料 ,用蟹肉和鱼肉培育稚螺。试验共孵化出幼体 5 5 0万粒 ,培育出 5 .5～ 1 7.5mm的稚螺 40万粒 ,培育成活率为 8%。
In order to explore the Artifactus orientalis artificial seedling technology, conducted indoor artificial seedling experiment. The progenitor was transported back to the experimental base from Zhanjiang Institute of Fisheries by cooling-drying method to control the incubation pond water depth 25 ~ 30cm, the proportion of seawater 1.107, water temperature 28 ~ 30 ℃, to maintain the inflatable and water stimulation Feed fresh crab and fish. Collect the pro-spawning oocysts, rinse and disinfect, and then hatch into the incubator. Cultivate single-cell algae for the feed of Eupolyphaga larvae, crab and fish nurture juveniles. A total of 55,000 larvae were hatched in the experiment, which raised 400,000 juveniles from 5.5 to 7.57 mm in diameter and gave a survival rate of 8%.
