Four groups of Tilapia nilotica were fed in different ranges of temperature (constant temperature of 28℃ and 30℃; periodic fluctuating temperature of 28±4℃ and 30±4℃)in the laboratory. The increasing body weight and oxygen consuming rate were measured. The energy assimilating rate and tissue growing rate (K_2) were calculated. The results indicated that the growth of fluctuating temperature groups was faster, and the daily increase weight and percentage increase weight were higher than that of the controlled ones. In addition, the energy assimilating rate and tissue growing rate in the fluctuating temperature groups were higher than that of the controlled groups, except that the tissue growing rate in the fluctuating temperature group at 30±4℃ was lowest. The mechanism that fluctuating temperature promoted the growth of Tilapia nilotic(?) and its significance in productive practice were discussed and analysed.

在实验室内不同温度条件(恒温28℃、30℃和周期性变温28±4℃、30±4℃)下,分四组饲养罗非鱼,测定其增重、耗氧率、并推算能量同化率和组织生长效率(K_2)。结果表明,变温组均比相应恒温组生长迅速。其中以变温28±4℃组日增重最快,增重百分率最高,其次为变温30±4℃组,恒温28℃组日增重最慢,增重百分率最低。能量同化率和组织生长效率也以变温28±4℃组最高;30±4℃组能量同化率虽较高,但组织生长效率却最低。本文对变温促进罗非鱼生长的机理和其在生产实践中的意义进行了分析与探讨。

The relationship between day energy growth (G) and day energy intake (DEI) can be described as G=a+bDEI.By analysing, we established the energy budget of fine Scale fish of 3 size groups in 7%, 5%, 2.5% and 1% feeding levels according to winberg formula C+G+ (F+U). The feeding level should not be lowwer than 5% in fish farming for fine scale fish.
