研究了不同投喂频率1次/d、2次/d(周日不投)、2次/d和3次/d对星斑川鲽幼鱼生长、摄食率、饲料利用情况和全鱼及其组织组成的影响.结果表明: 随着投喂频率的增加,星斑川鲽幼鱼的增重率、特定生长率和摄食率显著升高,2次/d(周日不投)组增重率和特定生长率显著高于1次/d组(P<0.05),但与2次/d和3次/d组无显著性差异(P>0.05);2次/d(周日不投)组饲料转化率和蛋白质效率稍高于2次/d和3次/d组,但各组之间差异不显著(P>0.05);全鱼水分和粗蛋白含量不受投喂频率的显著影响(P>0.05),全鱼粗脂肪含量2次/d(周日不投)组显著低于2次/d组(P<0.05),全鱼灰分含量1 次/d组显著高于2次/d(周日不投)组和3次/d组(P<0.05),其余各组差异不显著(P>0.05);肌肉水分含量随投喂频率增加而显著降低(P<0.05),肌肉粗蛋白和粗脂肪含量与水分含量呈负相关,肌肉灰分含量1 次/d组显著高于2次/d组(P<0.05),其余各组无显著性差异(P>0.05);肝脏水分和粗脂肪含量各组之间无显著性差异(P>0.05),肝脏粗蛋白含量1 次/d组显著低于其余各组(P<0.05),其余各组之间差异不显著(P>0.05).

A study was conducted to assess the effects of different feeding frequency (1, 2, 3 times per day and 2 times per day but Sunday) on growth performance, feed utilization, body and tissue composition of juvenile Starry Flounder (54.52 g). The results showed that weight growth rate, specific growth rate and feeding rate were enhanced significantly by feeding frequency (P<0.05). Weight growth rate and specific growth rate of 2 times per day but Sunday was significantly higher than 1 time per day (P<0.05) but no significant difference with the other groups. Body moisture and protein content were not significantly affected by feeding frequency (P>0.05). Lipid content of whole body under 2 times per day but Sunday was significantly lower than 2 times per day (P<0.05). Muscle moisture content was decreased significantly by feeding frequency (P<0.05). Muscle protein and lipid content has negative correlation with moisture content.
