Abstract

The aim of this study was investigation of growth rate, survival and activity of DIGESTIVE ENZYMES (a-amylase and ALKALINE PHOSPHATASE) in fish larvae fed Artemia nauplii. The experiment was performed in 115-liter glass tanks containing 7000 pieces of kutum larvae with an average initial weight of 5.1 mg (2 days after hatching). Samples for analysis of digestive enzyme activity were taken randomly at 2, 3, 5, 8, 10, 13, 17, 23, 27, 30. The results displayed that the stocking in high density to decrease growth efficiency but there was not considerable effect on survival rate larvae. In the present study was observed a significant increase in activity of AMYLASE from 23 to 30 days as the highest AMYLASE activity was found at 30 days after hatching. The high content of glycogen and carbohydrates in live food may be to stimulate synthesis and secretion of AMYLASE. An early peak of activity in ALKALINE PHOSPHATASE enzyme activity was observed at day 8 after hatching the indicating the maturation process in the intestines of kutum larvae.
