| 摘 要： | 对比研究了模拟自然昼夜温度变化节律的4个变温(22±2)、(25±2)、(28±2)和(31±2)℃与相应的恒温22、25、28和31℃下中国对虾(F ennerop enaeus ch inensis O sbeck)生长和能量收支的差异。结果表明,对虾在(22±2)℃、(25±2)℃和(28±2)℃变温条件下的生长率显著高于相应的恒温,但(31±2)℃与恒温31℃相比没有显著差异。与相应的恒温相比,(25±2)℃、(28±2)℃和(31±2)℃变温下对虾的摄食量显著增大,(22±2)℃、(25±2)℃和(28±2)℃变温下对虾的饵料转化率则显著提高。但变温下对虾对食物的消化率与相应的恒温相比没有显著差异。能量收支研究结果则发现,(22±2)℃、(25±2)℃和(28±2)℃变温下对虾摄食能中,用于生长的能量比例显著增加,而(31±2)℃与31℃相比则未见显著差异。从而表明,变温促长的主要机制可归因于变温下摄食量的增大、饵料转化率的提高及其摄食能中用于生长能比例的增加。

| Abstract: | Temperature fluctuates diurnally and seasonally in natural aquatic systems.However,most previous studies on the effects of temperature on the growth of Chinese shrimp(Fenneropenaeus chinensis Osbeck) usually were conducted at constant temperature with a assumption that growth at a constant temperature is close to that at fluctuating temperature with a mean similar to the constant one.Current literature on the effect of fluctuating temperature on the growth of Chinese shrimp is fragmental..The growth rate,fo... |
