在不同的摄食水平(饥饿—最大量)及温度(5—15℃)下,对1—5g的真(鱼岁)的摄食量、排粪量、排泄量、代谢量,生长量及生化组成作了测定。真(鱼岁)的最大摄食量随体重及温度增加而增加。食物能量平均有6.5％损失于粪便中,5.1％损失于排泄物中。摄食代谢随摄食量增加而增加。在同一温度下,特定生长率与摄食量的关系是一减速增长曲线。当摄食不受限制时,生长率随温度增加而增加;当摄食受限制时,生长率随温度增加而下降。鱼体的干物质含量及能量含量随摄食量增加而增加。
At different feeding levels (starvation - maximum) and temperature (5-15 ℃), the intakes, excretion, excretion, metabolism, growth and biochemical composition Made a determination. True (fish years) the maximum food intake increases with body weight and temperature. On average, 6.5% of food energy is lost in the stool and 5.1% is lost in excrement. Ingestion metabolism increases with food intake. At the same temperature, the relationship between specific growth rate and food intake is a deceleration growth curve. When feeding is unrestricted, the growth rate increases with increasing temperature; when feeding is limited, the growth rate decreases with increasing temperature. The dry matter content and energy content of fish increased with food intake.
