The effect of Artemia nauplii (Artemia franciscana) enriched with different commercial products on the growth performance of the larvae of freshwater angelfish, Pterophyllum scalare (Lichtenstein, 1823)

The present study was planned to determine an optimum live-feeding protocol for angelfish larvae (Pterophyllum scalare). Larvae with initial weight of 0.10 mg, a length 4.5 mm, and depth 1 mm were reared on three different feeding regimens 30 days. All experimental larval groups fed Artemia nauplii from the end yolk-sac resorption. control treatment (Group I) maintained days 14-28, + dry feed 29 30. Group II enriched Algamac 3050 14-28 30, whereas III Red Pepper food highest (37.8±0.51 mg) (15.8±0.35 mm) determined in significant differences group (p<0.05). However, enrichment treatments comparable terms growth performance (p>0.05). survival rate varied between 70-75% without Overall, results suggest that administration during first two weeks after hatching then over following followed by gradual weaning onto feed.
