Silver pompano (Trachinotus blochii) is one of the high economic fisheries commodities that are easily cultivated and easy to sell. One obstacle in aquaculture is the high cost of feed. Chromium and yeast have the potential to improve the performance of digestive enzymes and increase the activity of insulin function. P. this research aims to find out the effect of usage chromium-yeast as feed additives to the growth rate of enlargement of star Silver pompano (Trachinotus blochii). The raw materials used are Silver pompano, chromium, yeast, and commercial feed. This research design uses a Completely Randomized Design (CRD) with four chromium dose treatments-yeast different with three repetitions. Data analyzed with ANOVA and Duncan test with confidence level 95%. The results showed that the concentration of chromium-yeast addition in feed can increase growth and feed utilization efficiency to an increase in the average daily growth rate which is significantly different, the efficiency of feed utilization and life sustainability that no different real. Addition of chromium-yeast feed with a concentration of 3.20 ppm can produce a daily growth rate of 0.32 grams / day, 85% utilization of feed efficiency and survival (97%) is the best.
