Studies on mix- cultivation of Paralichthys olivaceus and Cynoglosus sp. in southern Fujian
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。This experiment was conducted to study the mix- cultivation of Paralichthys olivaceus,Cynoglosus sp. and the domestication of Cynoglosus sp. in southern Fujian.4 566 fries of P.olivaceus with the body length of 19.8 cm were got from hatchery farm in Rushan,Shandong,and 1 280 fries of Cynoglosus sp.with the body length of 10￣13 cm captured from the natural waters of Zhangpu,Fujian.This 180 days experiment was conducted under water temperature 10 ￣28 ,salinity 28 2,pH 7.8￣8.5 to determine effects of mix- cultured. The results showed that the total survival rate of the mis- cultivation was 69.2%,the production of them,1 209 kg.the cultivation of P.olivaceus and the mix- cultivation of it & Cynoglosus sp. in winter in southern Fujian were feasible,and that the domestication of Cynoglosus fries captured from the natural waters of Zhangpu was first a successful experiment.The paper discussed the affected factors of the economic benefit of P.olivaceus and Cynoglosus sp. in detail.
