Daphnia magna, a freshwater zooplankton organism, is a sustainable alternative to Artemia nauplii for feeding fish larvae. Artemia nauplii have been used as a traditional live food source for juvenile fishes in aquaculture due to their high nutritional value and availability. However, concerns regarding the sustainability, cost, and environmental influence of Artemia nauplii cultivation have prompted the search for alternative live-food sources. Daphnia magna, with its inherent nutritional composition, ease of cultivation, and potential for mass production, holds promise as a viable alternative. Though there were slight differences in the adjacent alignment of Daphnia magna and Artemia nauplii. The relative examination of data on two individual live feeds showed that at the end of the 21-day experiment, that means survival rate of the juveniles of Pterophyllum scalare was high in Daphnia magna as compared to Artemia nauplii as a food source. Survival rates were achieved 85%-95% in three experiments with Daphnia magna as food compared to 74%-79% with Artemia nauplii. The highest values (5.44 %, 5.65 %, and 5.80%) in particular growth rates were also obtained in three different experiments where the Daphnia magna is used as fed. The cost of production of Daphnia magna as food per gram is much less compared to that of Artemia nauplii.
