| 摘 要： | 采用封闭流水式实验方法,研究了氨氮、温度和体重对大口黑鲈(Micropterussalmoides)耗氧率、窒息点的影响。结果表明:在设定的总氨氮浓度0—8.61mg/L范围,随着氨氮浓度增加,大口黑鲈幼鱼耗氧率呈现先增加后降低的趋势,峰值为0.338mg/(g·h),窒息点随着氨氮浓度的增加而递增,影响显著(P0.05);在13—33°C的实验温度范围,随着温度升高,耗氧率先增加,在29°C时达到峰值0.392mg/(g·h),随后出现下降。在体重6.66—15.87g范围,耗氧率随着体重的增加而下降,最低值为0.112mg/(g·h);耗氧率存在明显的昼夜节律变化,夜均0.214mg/(g·h)日均0.199mg/(g·h),二者差异显著(P0.05),并在2:00—6:00和18:00—20:00时间段出现两个峰值。
