摘要
综述了黄鲷的形态、生态、生长及繁殖等生物学特征,报道了黄鲷亲鱼选择培养及人工促熟催产技术,胚胎发育、仔鱼的生长发育情况和苗种培育等有关技术。研究结果表明:注射LHRH-A3和LHRH-A2+DOM催产后,经营养强化培育的野生黄鲷可有规律地连续产卵。产卵一般在10:00～16:00时进行,产卵期长达45～57 d。在培育水温20～22℃、盐度28～30时,受精卵经35～37 h完成胚胎发育,孵出仔鱼,孵化率为89%,孵出的仔鱼活泼健壮。
This paper deals with the description of biological characteristics of morphology,ecology,growth and propagation of yellow sea bream Dentex tumifrons.Bloodstocks collection and rearing,accelerating mature,artificial hastening parturition,embryonic development are studied and reported in this paper,as well as growth and development of larvae and juvenile and indoor seed rearing of Dentex tumifrons.The results showed that the brood fish was induced to spawn by injection of hormone(LHRH-A3 and LHRH-A2+DOM).It ...
