The aim of the study is to determine the effect of the feed type (Daphnia pulex-based feed and Dajana nano gran brand) on the water quality (presence of microorganisms and suspended solids) and on the growth and survival of Macrobrachium rosenbergii shrimp larvae. The study implementation plan involved 4 groups of shrimps placed under the same conditions, which were evaluated for 14 weeks through periodic observations and biometrics. The data obtained recorded significant differences between the groups where the best growth and survival results were obtained in organisms that received Dajana nano gran feed, regardless of water quality. In addition, the values of protein in shrimp meat up to 45% and different amounts of fatty acids were obtained. It was determined that the Daphnia pulex-based feed showed lower results in the growth rate and survival rate of Macrobrachium rosenbergii shrimp.
