The growth and reproduction of Daphnia magna fed with Microcystis viridis and Chlorella spp respectively and 20% fish oil + 80% yeast and yeast were *** intrinsic rate of natural increase of Daphnia magna(rm) was 0.243 fed with Microcystis viridis,0.301 with Chlorella spp.,0.244 with 20% fish oil + 80% yeast and 0.193 with *** result showed that:Daphnia magna fed with Microcystis viridis had lower growth rates than that fed with Chlorella *** 20% fish oil + 80% yeast which both had full fatty *** the Daphnia magna fed with yeast was the *** the fatty acids composition of diet may affect the growth of Daphnia *** paper further examined total lipids and main HUFA(EPA and DHA) compositions of the continuous three generations of Daphnia magna(in order to get rid of the effects of former diet) fed with different of above diets(except the yeast).The result showed that:the three generations of the *** fed with Microcystis viridishad the lowest total lipids and the percentages of the HUFA(EPA,and no DHA) have a significant decrease and get the lowest EPA in the final experiment because of the very low HUFA especially EPA and DHA in Microcystis *** the results indicate that Microcystis viridis with low HUFA made the lower growth rate,spawning rate and hatching rate of Daphnia magna.
