Effect of Various Concentrations of Protein, Fat and Carbohydrate in Diet on Growth and Body Composition of Most Economically Important Fish in Pakistan, Labeo rohita

Abstract

200 L. rohita fingerlings were distributed into ten treatments, each supplemented with experimental diet containing 17.1+0.04kJ DE g-1 dietary energy. In experiment I: 35% (35P), 40% (40P) and 45% protein (45P), experiment II: 7% (7F), 12% (12F), 17% fat (17F) and in experiment III: 3% (3C), 5% (5C) and 7% carbohydrate (7C) containing diets were supplemented for 60 days. Growth performance and various parameters of body composition (ash, fat, carbohydrates) were determined in wet and dry fish weight in order to demonstrate the effect of various diet composition on nutritional value of most economically important carp, Labeo rohita. Study revealed that diets with increasing carbohydrate levels shows better growth among the various dietary treatments of Labeo rohita can.
