Trivalent chromium (CR+3) in dietary carbohydrate and its effect on the growth of commonly cultivated fish

Trivalent chromium (cr+3) is an essential trace mineral for fish bio-physiological functions. researches on cr+3 in the form of organic compound indicated that the mineral affected the bio-activity of insulin,the blood glucose influx,and subsequently the blood glucose metabolic rate. by increasing the blood glucose metabolism,dietary carbohydrate will be more efficiently used as a main energy source,thereby,dietary protein could be efficiently retained as for somatic growth. researches on various feeding habits of fish (e.g. gouramy-herbivorous fish,tilapia-omnivorous fish,and catfish-carnivorous fish) showed that dietary cr+3 in certain amount increased diet utilization and the fish growth. © 2016 penerbit utm press. all rights reserved.
