There has been high demand in aquaculture for live feed as a starter feed for fish and crustacean larvae. The Moina sp is a potential live-feed species due to its availability in most of the natural water resource, high nutritional value and the potential to replace other types of zooplankton, which are commonly used in aquaculture, such as Artemia. This study aims to compare the survival, growth, and proximate analyses of Penaeus monodon larvae fed with different enriched Moina sp. The Penaeus monodon larvae, which are fed on Moina sp were enriched with different formulas, comprising yeast, canola oil, Nannochloropsis sp, and Chlorella sp. This study was conducted at the hatchery of Faculty of Fisheries and Food Sciences (FPSM) in Universiti Malaysia Terengganu. The Moina sp. was cultured for 6 generations before starting the experiment. Enriched Moina sp was placed in triplicates in an aquarium, reared for 30 days, and fed to 450 individuals. The highest specific growth rate of P. monodon was recorded when fed with Moina-enriched yeast (17.22 ± 0.10 %) with a survival rate of 91.78 ± 1.67 %. Overall, the Moina-enriched yeast displayed the best result compared to other enrichment methods, especially towards the biochemical compositions of the shrimp. The mean value of protein, lipid, moisture and ash amounted to 64.04 ± 0.40 %, 4.91 ± 2.43 %, 16.89 ± 2.75 %, and 10.38 ± 2.05 % respectively. It was found that the enrichment methods using yeast were effective on Moina sp, and improved the nutritional composition of shrimp larvae and the larval performance of P. monodon postlarvae production in hatcheries by utilising low-cost enriched Moina sp as live food.
