The Effects Of Varying Protein Levels On The Growth, Survival And Yield Of Penaeus Indicus Under Iranian Condition

Four shrimp diets for Penaus indicus were formulated using available indigenous feed ingredients (fish meal, shrimp meal, soybean meal, wheat flour, corn flour and corn oil ) using linear programming techniques All the diets were isocaloric ( 400 kca1/100g ), containing 5 to 115% fat The dietary...
