温度对草鱼能量收支的影响

摘要:
于1992年4月 - 1992年5月在22,26及30°C下,以莴苣叶为食物,不限量摄食,测定草鱼的能量收支。结果表明,草鱼摄食率及生长率均随温度上升而增加;最大摄食率(CW:% W/d)与水温(T:°C)的关系为:CW=0.0405T2.324;温度对食物能分配于能量收支各组分的比例没有显著影响,在3个温度下测定的平均能量收支式为:100C=29.89F+3.30U+52.48R十14.34G,式中C为食物能,F为排粪能,U为排泄能,R为代谢能,G为生长能。

Abstract:
Energy budgets were constructed for fingerling grass carp (Ctenopharyngodon idellus Val.) at 22, 26 and 30°C, based on an experiment conducted during April - May, 1992. The fish were fed lettuce leaves using Lactuca sativa var. asparagina rations for a period of 15 days. Food consumption, faecal production and growth were estimated directly, and nitrogen excretion and metabolism estimated indirectly from nitrogen and energy budgets respectively. Rates of maximum food consumption and growth increased with increased water temperature. The relationship between maximum rate of food consumption (CW; % body weight day-1) and temperature (T: °C) was: CW= 0.0405T2.324. Temperature had no significant effects on the proportions of food energy allocated to each component of the energy budget. The average energy budget was: 100C=29.89F+3.30U+52.48R十14.34G, where C is food consumption, F is faecal production, U is excretion, R is metabolism and G is growth.
Key words:  Temperature, Grass carp, Energy budget, Growth
