INFLUENCE OF TEMPERATURE ON PHYSIOLOGICAL CHARACTERISTICS OF PLAGIOGNATHOPS MICROLEPIS BLEEKER

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) ．
