摘 要: 研究闭合循环水养殖条件下驼背鲈(Cromileptesaltivelis)和斜带石斑鱼 (Epinepheluscoioides)的生长特性。经343d养殖 ,驼背鲈幼鱼平均体质量由24.16g增加到124.4g,平均日生长率为1.2 % ,体质量与养殖时间的关系式为M=32.674e0.0048t,体质量与体长的关系式为M=0.0042L3.6184;斜带石斑鱼幼鱼体质量由20.10g增加到490g,平均日生长率为6.8% ,体质量与养殖时间的关系式为M=34.319e0.0984t,体质量与体长的关系式为M=0.0656L2.7102。 Two finfish species, Cromileptes altivelis and Epinephelus coioides were cultured in a closed recirculating aquacultural system.Growth characteristics were studied. After 343 days' culture, the average body mass of C. altivelis increased from 24.16 g to 124.4 g, and E. coioides from 20.10 g to 490 g. For growth at an exponential rate, the body mass (M) of C. altivelis and E. coioides at culture time (t) could be calculated as: M=32.674e0.0048t and M=34.319e0.0136t, respectively. Daily body mass growth rates were 1.2% for C.altivelis and 6.8% for E.coioides. In addition, the relationships between body length(L) and body mass(M) were represented as: for C.altivelis, M=0.0042L3.6184, and, for E.coioides, M=0.0656L2.7102.
