摘要: 研究了不同温度对细鳞斜颌鲴(Plagiognathops Microlepis Bleeker)生理学特性的影响。结果表明:细鳞斜颌鲴的摄食率、消化率、耗氧率和窒息点均随温度的升高而显著增大(P<0.05)。对摄食与饥饿状态下细鳞斜颌鲴的排氨率均随温度的升高而增大,在25℃时达到最大值。在相同温度下,摄食的细鳞斜颌鲴排氨率显著大于饥饿状态下细鳞斜颌鲴排氨率(P<0.05)。Abstract: The paper studied the effects of different temperatures ( 10，15，20，25，35 ℃) on physiological characteristics of Plagiognathops Microlepis Bleeker． The results showed that the rates of ingestion，digestion，respiration and suffocation point of Plagiognathops Microlepis Bleeker significantly increased with temperature ( P ＜ 0. 05) ． In addition，ammonia excretion rates in both fasting and over fed Plagiognathops Microlepis Bleeker increased with temperature and reached the peak at 25 ℃． At the same temperature，ammonia excretion rate of over fed Plagiognathops Microlepis Bleeker was greater than the rate of the fasting Plagiognathops Microlepis Bleeker ( P ＜ 0. 05) ．
