Chromium trivalent (Cr3+) were part of the chromodulin which can activate insulin. Insulin can promote the glucose intake into cell, so that glucose can be used as energy source of the body. If glucose were optimized, then the energy that came from feed protein can fully be stored inside the body.  The aim of this experiment was to determine the effect of chromium trivalent in fish feed to growth and protein and fat retention in fish body.

There were three experimental feed with iso protein and iso energy but with different chromium doze (0.00, 1.33, 2.23 and 3.96 ppm) used in this experiment. The experimental feeds were given 3 times a day at satiation. Initial fish weight were 5.31±0.02 g. 12 aquarium were used and each contain 20 fish/tank and cultured for 50 d. after 50 d, the fish were measured for average daily growth. The total feed amounts were measured to find feed efficiency. Fish body sample were analyzed using proximate to find fat and protein retention.

After the experiment, the average body weights were increased. The final fish weights for the experimental feed were higher than the control feed and the highest final weight were achieved in 1.33  ppm Cr3+. The protein and fat retention were higher in feed which contain chromium trivalent compared to control (0.00 ppm Cr3+).

By adding chromium into fish feed will effect carbohydrate metabolism as energy source and therefore can retent the protein and fat from feed inside the fish body.
