Climate change, sea water rises and human activities are predicted to result in increase<br />

of salt concentration on freshwater habitat. Moina macrocopa that originally from<br />

freshwater cladoceran only can tolerate certain ranges of salinity. This study compared<br />

the effect of different ranges salinity on growth, survival and reproduction of the M.<br />

macrocopa. The salinity used in this study consisted of six different ranges (0ppt, 4ppt,<br />

6ppt, 8ppt, 12ppt, and 15ppt) which were tested to the M. macrocopa. The experiment<br />

was carried out for 15 days and the survival, growth and reproduction (average initial<br />

age of reproduction, average longevity, net reproduction rate, gross reproduction rate,<br />

generation time, intrinsic rate of population) were used to examine the toleration of<br />

M. macrocopa towards different ranges of salinity. Survival and reproduction of M.<br />

macrocopa were significantly affected by the different ranges of salinity (P
