摘要
试验研究了舟山牙鲆人工培育及促熟催产中的技术措施。采用自然海区捕获的牙鲆亲鱼，逐年筛选、精心培育，共获得健康的2—4龄成熟亲鱼300尾（雄鱼200尾、雌鱼100尾），体重1000～5000g。在自然产卵和外源激素HCG（1500IU／kg）及LHRH—A3（5μg／kg）的作用下（雄鱼减半），共采卵536．2×10^4粒，上浮率51．3％，受精率69．5％，孵化率84．2％。与自然产卵相比，激素催产产卵数量多，受精率和孵化率相对偏低：而自然产卵受精率和孵化率高，但产卵不够集中且数量相对较少。
In this paper, broodstock cultivation and artificial propagation technique of ZhouShan Flounder （ aralichthys olivaceus ） were studied. Three hundred 2 -4 years matured broodstock （female 200, male 100） were obtained from natural sea area by effective selecting gradually, that the body weight were varied between 1 000 g and 5 000 g. By the method of spawning naturally and injecting the hormone HCG （ 1500 IU/ kg） and LHRH-A3 （5μg/kg） in female broodstock, but HCG and LHRH-A3 halved in male broodstock, 536. 2 × 10^4 eggs were gained. The float-rate, fertilization-rate, and hatch-rate were 51.3% , 69.5% , and 84.2% respectively. Compared with natural spawning, there were more eggs by injecting the hormone, while the fertilization-rate and hatch-rate were lower. Though the fertilization-rate and hatch-rate were high, natural spawning had fewer eggs and finished time after time.
