Abstract
Five isonitrogenous and isoenergetic diets were composed to investigate the effects of incorporation of potato protein concentrate (PPC) in the diet of rainbow trout, Oncorhynchus mykiss (Walbaum), on feeding rate, growth, feed utilization and body composition. The experimental diets contained 0, 22, 56, 89 and 111 g kg-1 PPC, respectively. A 4-week trial was conducted at about 12°C. The results showed that with increased incorporation levels of PPC, feeding rate, growth and feed efficiency decreased significantly. Incorporation of PPC in the diets significantly decreased the dry matter content and fat content of fish body, while protein and ash contents increased.
