以天然捕获的多鳞鱚作为亲鱼进行人工繁殖。结果表明:在水温27.5~31.5℃、盐度18~31、pH 8.0~8.5的条件下,经促熟培育自然产卵,10批次共获得受精卵67×104粒,孵出仔鱼42.6×104尾,受精率37.2%~89.3%,孵化率24.8%~97.6%;在水温29~30℃、盐度28、pH 8.4的海水中多鳞鱚胚胎历时14 h 40 min完成整个胚胎发育孵化出膜,经35 d培育出平均全长35 mm的幼鱼约2.8×104尾,育苗成活率达24.6%。
Artificial reproduction of the natural catfish Scleractinidae as a broodstock. The results showed that the fertilized eggs were naturally spawned at the temperature of 27.5 ~ 31.5 ℃, the salinity of 18 ~ 31 and the pH value of 8.0 ~ 8.5 at a temperature of 27.5 ~ 31.5 ℃, and the number of fertilized eggs was 67 × 104 in 10 batches. The larvae hatched 42.6 × 104 The fertilization rate was 37.2% -89.3% and the hatching rate was 24.8% -97.6%. In the water temperature of 29-30 ℃, the salinity of 28, pH 8.4, After 35 days, the average length of 35 mm juvenile fish was about 2.8 × 104 tail, seedling survival rate of 24.6%.
