摘要
在试验条件下,对网箱培育鞍带石斑鱼亲鱼人工培育的方法和人工催产受精卵的情况进行了详细的描述,并对比不同的生物饵料作为鞍带石斑鱼仔鱼的开口饵料的开口成功率,从而选择更合适的开口生物饵料,提高仔鱼的成活率。结果表明：在2007年7—9月,人工催产了55尾鞍带石斑鱼亲鱼,产卵11 559 g,获得的受精卵较少,仅725 g,受精率只有4.42%~8.78%,鞍带石斑鱼于3日龄开始摄食,投入原生动物的仔鱼成活率最高,投入轮虫的次之。
This paper described the ways to culture broodstocks of Epinephelus lanceolatus and the states about artificially spawning fertilized eggs in detail,and contrasted the effects of different kinds of mouth-open preys on survival rates of Epinephelus lanceolatus,in order to improve the survival rate of Epinephelus lanceolatus.The results showed that from July to September in 2007,fifty-five broodstocks Epinephelus lanceolatus were artificially spawned and produced 11 559 g eggs,but the weight of fertilized eggs were only 725 g.The fertilized rate was just between 4.42% and 8.78%.The survival rate of Epinephelus lanceolatus feeding on protozoa was the highest.Additionally,the survival rate of that feeding on rotifers was the second.
