摘要: ABSTRACT Rearing of chironomid larvae was conducted under laboratory conditions, to study the growth rate (weight & length) different feeding systems. Three types food were used , first Tetramin Flaked commercially available fish (D1) nthe 2 d algae (Scenedesmus sp., D2) and 3 rd baker yeast (D3). Larvae have mean initial length 1.5mm. weight 0.99 µg. replicates performed for each treatment. The three diets significantly (P<0.05) effect on both larvae, but fed D1 showed highest which represented by 36.68 µg 9.29 mm, respectively. Followed those D3 7.03mm 31.03 weight, while D2 lowest values (6.28mm.) (27.08 µg.). percentage protein (51.15%) D1, followed (49.45%), value 26.45%. lipid content (12.04%) it 13.25 14.22% D3, Most essential amino acids such as arginine, histidine methionine, phenylanine isoleucine, leucine lysine higher in onTetramin, than other two diets. present work revealed good nutritional tetramin.
