摘　　要：放养平均全长(29.95±2.51)cm、平均体重(357.00±8.31)g和平均全长(11.63±1.13)cm、平均体重(19.85±1.23)g两种规格的云龙石斑鱼(云纹石斑鱼♀×鞍带石斑鱼♂)鱼种进行深海网箱养殖试验。试验期水温为14.2~29.2℃,投喂含46%~48%粗蛋白的石斑鱼配合饲料,经12个月饲养,大规格云龙石斑鱼平均体重达(1650.22±20.23)g、平均全长达(44.72±3.73)cm,小规格云龙石斑鱼平均体重达(480.20±22.32)g、平均全长达(32.41±3.53)cm,饲料系数为1.22。大规格云龙石斑鱼体重和全长的最优回归方程为幂函数方程W=0.001L^(3.667),小规格云龙石斑鱼体重和全长的最优回归方程为幂函数方程W=0.011L^(3.142)。云龙石斑鱼深海网箱养殖最适水温为21.2~28.7℃。试验结果表明云龙石斑鱼适合福州深海网箱养殖。The“Yunlong grouper”,Epinephelus moara♀×Epinephelus lanceolatus♂,were reared in the sea area under the condition of cage-culture.The initial average body weight of big size of juvenile“Yunlong grouper”was(357.00±8.31)g,and the average total length was(29.95±2.51)cm,the initial average body weight of small size of juvenile“Yunlong grouper”was(19.85±1.23)g,and the average total length was(11.63±1.13)cm.The water temperature ranged between 14.2℃and 29.2℃during the experiment.The fish was feed with grouper formula feed,with 46%~48%crude protein.After 12 months of cultivation,the average body weight and total length of big size of juvenile“Yunlong grouper”reached to(1650.22±20.23)g and(44.72±3.73)cm,the average body weight and total length of small size of juvenile“Yunlong grouper”reached to(480.20±22.32)g and(32.41±3.53)cm,and the feed coefficient was 1.22.The optimal regression equation for the body weight and total length of big size of juvenile“Yunlong grouper”was W=0.001L^(3.667),the optimal regression equation for the body weight and total length of small size of juvenile“Yunlong grouper”was W=0.011L^(3.142).The optimum water temperature for deep-sea cage-culture of“Yunlong grouper”ranged between 21.2℃and 28.7℃。The results showed that deep-sea cage-culture can be adapted to Yunlong grouper in Fuzhou.
