[目的]研究野生葛氏鲈塘鳢(Perccottus glenii)鱼体的营养成分及能量密度的季节变化规律.[方法] 2013年10月至2014年9月逐月采集松花江哈尔滨段野生葛氏鲈塘鳢50尾,通过营养学分析方法测定了鱼体的营养成分和能量密度的变化.[结果]野生葛氏鲈塘鳢的水分含量为76.95%~80.63%,灰分含量为1.51%~1.97%,粗脂肪含量为2.00%~2.57%,粗蛋白含量为13.37%~16.62%,能量密度为19.66~21.60 kJ/g.冬季葛氏鲈塘鳢的粗蛋白含量显著低于春季和夏季(P0.05).能量密度在冬季最低,夏季最高(P0.05).The energy density in winter was the lowest,and that in summer was the highest (P<0.05).[Conclusion] The crude content and energy density in wild P.glenii in winter were both the lowest,which might be caused by more protein and energy density of wild P.glenii in overwintering period.
