Nitrogen excretion and oxygen consumption on hyper intensive tilapia Oreochromis niloticus culture using three different commercial diets

ABSTRACT. The fish feed used in aquaculture systems has many nutritional factors like protein, fat, fiber, ash, and humidity; from these factors, one of great importance is protein. The protein of fish feed is obtained from fish meal, and the demand for fish meal has increased; this induces to incre...
