中文摘要:
      研究了低盐度(盐度为5)条件下,室内循环水养殖8月龄大黄鱼随着年龄的增长与同龄正常海水(盐度为35)网箱养殖大黄鱼生长情况以及肥满度的变化。研究结果表明正常海水盐度网箱养殖中的大黄鱼体质量显著大于同期淡化循环水养殖条件下大黄鱼的体质量(P<0.01),而在两种养殖模式下大黄鱼肥满度随着时间的变化上下波动,并且在繁殖季节大黄鱼的肥满度高于非繁殖季节。大黄鱼长期生长在盐度为5的海水中其卵巢可以发育成熟,但性腺指数低于正常海水中的大黄鱼的性腺指数,并且在成熟的大黄鱼卵巢中,淡化组的大黄鱼卵巢中成熟卵细胞所占比例明显低于正常海水组的大黄鱼。本实验为大黄鱼的淡化养殖和淡化养殖条件下的人工繁殖提供了理论依据。
英文摘要:
      We studied the changes of Pseudosciaena crocea at the age of 8 months in growth and fatness along with the change of age which was fed in the low salinity (salinity of 5) conditions, indoor recirculating aquaculture and same age marine cage cultured (salinity of 35) Pseudosciaena crocea. The results show that the growth rate of weight of normal seawater salinity cage cultured large yellow croaker was significantly higher than that cultured in the desalination circulating water. And in two different culture conditions, the fatness of large yellow croaker fluctuates over time, and the degree of fatness in breeding season of large yellow croaker is higher than that in non-breeding season. The gonad of large yellow croaker which grew up in salinity of 5 seawater can develop to maturity, but the gonadosomatic index is lower than that of the one that grew up in normal seawater. Furthermore, the gonadal mature egg cell proportion of desalination group was significantly lower than that of normal seawater group of large yellow croaker. In general, this experiment laid the foundation for breeding and artificial propagation of large yellow croaker in desalination culture conditions.
