将在近海捕获的14尾黑亲鱼放在海带育苗池内进行流水培育,让其自然产仔。共产健康仔鱼361400尾,产仔率达28.57%。以小球藻、轮虫、卤虫幼体、少量海捕天然浮游动物和鱼、虾肉糜为系列饵料,培育20~30天,育出全长14.2~30mm的稚鱼322198尾,平均成活率89.15%;单位水体平均出苗量为6712尾/m3。在18~24℃水温范围内,仔稚鱼的平均日增长量约为0.5mm。每3~5天轮流使用1mg/1的氯霉素,0.3mg/l的鱼虾安,可以有效地防治仔稚鱼的细菌性疾患;用0.05mg/l的孔雀石绿药浴15~20分钟,可以防治真菌疾患。
Fourteen black broodstock captured in the open sea were placed in kelp nursery ponds for running water to allow them to give birth naturally. Communist healthy larva 361,400 tail, litter rate of 28.57%. With chlorella, rotifers, Artemia larvae, a small amount of natural catching natural zooplankton and fish, shrimp meat for the series of bait, cultivate 20 to 30 days, bred a full length of 14.2 ~ 30mm juvenile 322198 tail, the average survival The rate of 89.15%; the average amount of water per unit of 6712 / m3. In 18 ~ 24 ℃ water temperature range, the average daily growth of larvae of fish is about 0.5mm. Every 3 to 5 days take turns 1mg / 1 chloramphenicol, 0.3mg / l fish shrimp Ann, can effectively prevent and treat larvae bacterial diseases; with 0.05mg / l malachite green medicine bath 15 ~ 20 minutes, can prevent fungal diseases.
