摘要(Abstract)：
在水温(28±1)℃,以配合饲料及最大摄食量的条件下,研究卵形鲳鲹(Trachinotus ovatus)幼鱼[初始体重(5.77±0.45)g]在盐度10、15、20、25、30和35下的生长及能量收支。结果表明:在盐度25时,湿重、干重、蛋白质及能量指标的特定生长率均达到最大值,分别为3.21%、2.06%、4.76%和4.66%;干重、蛋白质和能量指标的摄食率也达最大,分别为20.31%、13.57%和12.21%;干重、蛋白质和能量指标的转化效率也达最大,分别为35.61%、46.60%和52.78%。可见,盐度对卵形鲳鲹幼鱼的特定生长率、摄食率、转化效率及能量收支有显著影响。盐度对吸收效率则无显著影响,蛋白质和能量的平均吸收效率分别为94.91%和92.45%;在盐度25,卵形鲳鲹幼鱼得到最佳的能量分配模式,其收支方程为:100.00C=7.30F+10.13U+29.80R+52.77G。
