摘    要:本文报道了不同pH值(6.5、7.5和8.5)和不同Ca^2+浓度(38.8、61.1和78.8ppm)对日本沼是生长和能量收支的影响,实验结果表明,pH值对该虾的生长有一定的影响,Ca^2+和pH值在影响其生长的过程中可能有一定的交互作用,pH值和Ca^2+对该虾生长的影响主要是通过影响其能量摄入量实现的,本实验条件下,该虾摄入的能量平均有15.8%用于生长,1.8%作为粪便排出体外,其余用于呼

关 键 词:日本沼虾  生长  能量收支  pH钙离子

Abstract:The paper deals with the effects of PH (6. 5, 7.5 and 8. 5)and Ca2+ concentration(38.8, 61.1 and 78.8 ppm)on the growth and energy budget of a freshwater shrimp Macrobrachium nipguense. The results showed that PRvalue affected the growth of the shrimp, and there was interaction between PH and Ca2+ concentration in the process.PH and Ca2+ affected their growth throughaffecting mainly on their energy consumption.Under the experiment condition.the energy fed by the shrimp was allocated to grouch by 15.8N and faeoal Production by 1.8%.
Keywords:Macrobrachium nipponense  growth  energy budget  pH Ca2+
