Evaluation of Spirulina Supplemented Diet and Its Influence on Bioenergetics and Biochemical Parameters in the Fish Cirrhinus mrigala

Food intake is an important factor governing growth and reproduction and it is depend upon the quality and chemical composition of the feed. A comparative study was conducted to test the effect of Spirulina incorporated diet over the commercially available feed on bioenergetics and biochemical parameters of fish Cirrhinus mrigala. Spirulina incorporated diets were formulated to contain Spirulina at the level of 0.25, 0.50 and 1.0%. The results showed a better growth rate, feeding rate and absorption rate in the fish fed with Spirulina incorporated diet compared to commercial feed. The study also revealed that protein, carbohydrate and lipid contents were increased in fish with Spirulina incorporated diet.
