Abstract: The extreme environmental endurance and effects of temperature（25-32 ℃）,salinity（15-35）,and NH3-N（1.05-6.62 mg/L） on reproduction and population growth of water fleas Moina mongolica population（Jinnan 1982 and Jinnan 2006） acclimatized for different periods in order to evaluate the effects of long-term cultured in laboratory seawater on the population growth of the water fleas.The results showed that there were no significant differences in reproductive parameters and intrinsic growth（rm） between the two populations acclimatized at different temperatures,though there were significant differences in reproduction and population growth between the two populations acclimatized at different temperatures,with the optimum temperature of 28 ℃.The water fleas acclimatized at salinity varying from 15 to 35 had no significant differences in population growth.In different NH3-N levels,however,the water fleas acclimatized for longer period showed stronger endurance.From the comparison of the resultant data,no detrimental effects were found in M.mongolica cultured in seawater for long-term,but M.mongolica of 1982 had stronger thermal adaptability,indicating more suitable for the large-scale culture in seawater.
