摘要/Abstract

摘要： 于1996年7～8月在盐度为14的条件下,测定了台湾红罗非鱼(体重25.334～26.225g)在水温为22、28和34℃时的能量收支.结果表明,温度对台湾红罗非鱼的特定生长率,转化效率和最大摄食率均有显著影响,28℃时上述各值均达到最大,分别为1.79,60.01%和2.59%B·W·d^-1;对吸收率无显著影响,对干物质的吸收率的平均值为64.58%.温度对食物能分配于能量支出各部分的比例有显著影响,28℃时生长能所占比率最高,为26.49%,代谢能所占比率为37.23%.

Abstract: The energy budget of Taiwanese red tilapia hybrid (Oreochromis niloticus × O.mossambicus)with a body weight of 25.33～26.23g was measured at salinity 14 and at water temperature 22,28 and 34℃ in July-August 1996.The results showed that its specific growth rate,conversion effciency and maximum food consumption were significantly affected by temperature,and reached peaks of 1.79,60.01% and 2.59%B.W.d^-1 at 28℃.The effect of temperature on the absorption efficiency was not significant,with an average absorption efficiency 64.58%.The effect of temperature on the proportions of food energy allocated to each component of the energy budget was significant.The ratio of growth energy was the highest(26.4%) at temperature 28℃,and that of metabolism energy was 37.23%.
