Abstract

In the study, the effect of microphytes on the biomass of Daphnia magna, which is of great importance in the fishing industry, was studied. The concentration of fat and protein in the biomass of Daphnia magna fed with microphytes was investigated. Based on the experimental results, it is recommended to use the biomass of Daphnia species grown with Ankistrodesmus and Botryococcus microphytes as a source of food for raising fish larvae.
