本试验采用来自山东乳山人工培育,平均体长为19.8cm的牙鲆鱼苗4566尾和漳埔海区野生,体长10￣13cm的舌鳎鱼苗1280尾,在水温10￣28,盐度27￣30,pH值7.8￣8.5的条件下,进行为期180d的池塘混养和人工驯养。结果表明,总成活率为69.2%,总产量1209kg,牙鲆冬季南移养殖及与舌鳎混养是可行的,且舌鳎海区野生苗人工驯养初获成功。此外,本文还就影响牙鲆和舌鳎养殖效果和经济效益的因素进行了讨论。
In this study, 4566 Chinese flounder fry with an average body length of 19.8 cm and 1280 wild litura of Zhangpu sea area were cultured in Rushan, Shandong Province. The water temperature was 10-28 and the salinity was 27-30 , pH value of 7.8 ~ 8.5 under the conditions of a 180d pond polyculture and artificial domestication. The results showed that the total survival rate was 69.2%, and the total yield was 1209 kg. Paralichthys olivaceus was feasible for southward culture in winter and mixed with tongue ploys, and the artificial domestication of wild seedlings in tongue pies was initially successful. In addition, this article also discussed the flounder and tongue floss breeding effect and economic benefits of the factors are discussed.
