Abstract:在不同盐度、温度和饵料种类饲养条件下测定了台湾红罗非鱼幼鱼( 体重11.26~45 .56 g) 鱼体的生化成分和含能量。结果表明:在任何条件下台湾红罗非鱼幼鱼鱼体含水量与其蛋白质含量、脂肪含量和比能值分别存在显著的负线性相关关系,蛋白质和脂肪含量也分别与比能值显著相关,其中含水量与比能值的相关系数最高。因此,用含水量估计鱼体的生化成分及比能值简单可靠,鱼体生化成分受盐度和饵料等生态因子的影响,脂肪含量受盐度的影响有一定的变化规律,饵料种类( 日本刺沙蚕、混合藻液和颗粒饵料) 对鱼体生化成分的影响非常显著,对比能值的影响达到极显著水平,以日本刺沙蚕为饵料的鱼体蛋白质含量、脂肪含量及比能值均高于其他2 组,而摄食颗粒饵料的鱼体营养成分含量均最低
