摘要
本文研究了温度对饱食和饥饿状态下黑鱾(Girella melanichthys)幼鱼耗氧率和排氨率的影响。结果表明:在温度为15～30℃范围内,黑鱾幼鱼在饱食状态下的耗氧率、饥饿状态下的耗氧率、饱食状态下的排氨率和摄食率均随温度的升高而增加(P<0.01),30℃时达到最大,温度为32℃时,均下降;在温度为15～32℃范围内,黑鱾幼鱼在饥饿状态下的排氨率随温度升高而增加(P<0.01),32℃时达到最大。多项指标表明黑鱾幼鱼生长适温在30℃左右。
In this paper the influence of temperature on oxygen consumption and ammonia excretion of juvenile Girella melanichthys in hunger and satiety were studied. The results show that rate of oxygen consumption in both fasting and over fed fish, rate of ammonia excretion in the fasting fish is increased with the temperature between 15℃ and 30℃ （P 〈 0.01 ） and reaches to the peak at 30℃. While the rate is decreased when the temperature is at 32℃. For fasting fish, the ammonia excretion go up with temperature ascending in the range between 15℃ to 32℃ （ P 〈 0.01 ） , and arrives to the peak at 32℃. The results confirm that 30℃ is the optimal temperature for the fish growth.
