ON THE APPROPRIATE CONTENTS OF PROTEIN,FAT AND CALORIE-PROTEIN RATIO IN THE DIET FOR FRESHWATER SHRIMP (MACROBRACHIUM NIPPONENSE)

Yu Bingru Shanghai Fisheries University Shen Hong East China Environmental Monitoring Center, State Oceanic Administration, Shanghai  
The appropriate protein content, fat content and calorie-proteinratio in the diet for the freshwater shrimp have been studied. The experimentaldiets were composed of casein, dextrin, mixed oils, mixed vitamins and minerals.The shrimp used in the experiment were 1.77±0.23 grams in weight, and rearedat the water temperature of 21 and 25℃. Taking the weight gain, food conversionand α-amylase activities of liver-pancreas as evaluation indexes, the results of theexperiment indicate that 36.8-42.27% protein content, 6-12% fat content about 8Kcal/per gram protein calorie--protein ratio (G/P) and 3006-3561 Kcal/Kg in theformulated diet seems suitable. When the total calorie of the formulated diet is givena certain range, the α-amylase activities of liver-pancreas are enhanced with theincrease of carbohydrate content in the diet.
