“…in dry and paste form, compared with yeast alone, found that when Scenedesmus sp is ingested in frozen or dry form the organisms show 75 % fecundity, while when used in paste form a range of 55-95% fecundity is obtained in female cladocerans. Authors such as Ku et al, [22] , mention that cladoceran biomass can be measured by the number of organisms or the total weight obtained by the population of this small crustacean. This biomass can be considered as energy that is capable of passing from lower trophic levels to a higher trophic level (down-up), when this live food is available to be consumed by other benthic invertebrates and fish, whether ornamental or the first stages of commercial fish.…”

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.
