长臀鮠的人工繁殖试验

摘要

为长臀鮠的生产性繁殖和深入研究奠定基础,用马采酸地欧酮(DOM)、促黄体激素释放激素类似物( LRH-A2)和绒毛膜促性腺激素(HCG)组成混合催产剂催产4～5龄长臀鮠亲鱼47尾.结果表明:产卵率达75.75％,受精率为68.6％,孵化率为74.85％,鱼苗成活率达34.7％.用100目筛绢捞取个体较小的轮虫作为长臀鮠鱼苗的开口饵料,是苗种培育成功的关键技术措施.%47 4-5 years old parent C. Bouderius fish were treated with the mixed odinagogue of DOM, LRH-A2 and HCG lay a foundation for productive propagation and further research of C. Bouderius. The results showed that the egg laying rate, fertilization rate, hatching rate and survival rate were 75. 75%, 68. 6%, 74. 85% and 34. 7% respectively. Small rotifers collected from the bluteau with 100 meshes was the optimum bait for C. Bouderius fries, which was the key technical measure to culture C. Bouderiu fries successfully.
