ABSTRACT : Aquaculture is a dynamic industry that continues to provide consumers with a reasonably priced, high quality protein. The impact that any aquaculture system has on the environment, is today, and will continue to be, in the forefront when environmental issues are discussed. A better understanding of the dietary nutrient requirements of cultured fish species and a continual search for accessible, highly digestible proteins to replace expensive fishmeal is essential. This approach coupled with applying the ideal protein concept in the formulation of fish feeds can greatly ameliorate nitrogen pollution arising from fish production systems and increase profitability. Taking into account this consideration, the present investigation is carried out to evaluate protein efficiency ratio in freshwater fish Ctenopharengedon idella fed on different combinations of feeds formulated from readily available protein sources like soyabean and deoiled groundnut cake. The fishes fed on 100% formulated feed had highest PER values than other feeds.
