Abstract:

This research shows the population growth results of Daphnia sp. fed with three experimental diets using the microalgae Scenedesmus sp and Pinnularia sp supplemented with yeast for 60 days in 140 L of water container inoculated with 500 organisms. The experimental diets were: 1) Pinnularia sp + Scenedesmus sp + yeast; 2) Pinnularia sp + yeast; and 3) Scenedesmus sp + yeast. The results showed that Daphnia sp fed with diet 1 shows the highest population density with 2,903,714 organisms in 140 L, while the lowest population density was obtained with diet 3 with 2,208,205 organisms. The variable Ro fluctuated between 4, 380 to 5, 718 per female. The variable Tc remained stable over the 16 days and the variable r fluctuated between 0.37-0.58. The analysis of variance showed significant differences (p<0.05) among all the densities of the three experimental diets. The diet composed of diet 1 is recommended over diets 2 and 3.
