摘要:
在人工养殖条件下，进行环境调控及营养强化，诱导条斑星鲽（Verasper moseri）种鱼性腺成熟，通过人工授精获得受精卵，研究了受精卵的孵化，胚胎发育和苗种培育。结果表明，条斑星鲽受精卵在水温为8.6～10℃，盐度为31~33时，孵化时间需216 h，孵化率为29.0%～85.0%，苗种培育成活率为33.1%。

Artificial propagation and fry rearing of barfin flounder (Verasper moseri)
Abstract:
Gonadal maturation of barin flounder was induced by environmental and nurtrition regulation in artificial culture conditions and embryos were obtained by artificial fertilization. Then, the fry was reared in pond. The results indicated that the optimum hatching temperature was from 8.6℃to 10℃, and in such water temperature the hatchery period was about 216 h. The optimum hatching salinity for rearing was from 31 to 33, in which the hatching rates were 29.0%～85.0% and the survival rate of fry was about 33.1%.
