The effect of different feeds such as Chlorella vulgaris, Azolla pinnata and yeast on the population growth of Daphnia magna commonly found in freshwater systems

Abstract

The effect of different concentrations of Phytoplankton (Chlorella vulgaris, Azolla pinnata, and Saccharomyces cerevisiae) for fed with Daphnia magna on Survival, population and Growth rate for 20 days, algae cells are harvested, dried, powdered and used as feed and both species are easily maintained in culture. The experimental was E1, E2 and E3 small freshwater Zooplankton organisms (D. magna) fed with mix phytoplankton Feed different Concentration (%) 1, 2, 3, 4 and 5. The Experimental Daphnia magna on Survival, population and Growth rate Biochemical composition, of the three different species analyzed were significantly (p
