Extract

There is confusion in the literature as to the effects of carbohydrates in the diet of fishes. Warmwater, herbivorous fishes can digest more complex carbohydrates (Shiau and Chuang, 1995) while coldwater, carnivorous fish may digest glucose better. However high levels of dietary glucose may increase fat deposition in the viscera (Bergot, 1979). Furthermore, Kaushik and de Oliva-Teles (1985) reported that heat treatment of raw starch in diets for rainbow trout improved its utilisation. This study was conducted to determine the digestibility of diets containing raw wheat, extruded wheat, glucose and fish oil. The effects of these diets on growth performance and body composition of trout were also determined.
