摘  要：
于2003年至2006年,在浙江湖州市锦山鱼种场进行了鳡的亲鱼培育及人工繁殖的研究。结果表明:2龄野生鳡在池塘中经3年专塘培育后,雌雄鱼的性腺成熟率达100%;性腺成熟的亲鱼经催产,产卵率达100%、受精率86.5%、孵化率88.3%。与此同时,对鳡的胚胎发育作了详细观察。鳡受精卵在21~23℃下孵化至出膜,有效积温为705.34℃.h。

摘  要：
Studies on techniques of parent fish nursing and artificial propagation of Elopichthys bambusa were carried out in Jinshan fishery farm of Huzhou city in Zhejiang province from 2003 to 2006.The results showed that the two-year-old wild fish from Taihu lake after cultivating intensively in ponds for three years,the gonad maturity rate of the female and male fish was up to 100%.When the sexual mature parent fish were induced by both hormone injection and water flow,their average rates of spawning,fertilization and hatching were 100%,86.5% and 88.3% respectively.Furthermore,the process of embryonic development was also recorded.The fertilization eggs hatch under 21-23 ℃,and the effective accumulated temperature is 705.34 ℃·h.
