Silver pompano (Trachinotus blochii) is a fish that is in high demand and requires a large amount of production. The amount of production will be achieved if the fish is in a healthy condition. The health condition of the fish can be seen from its blood profile. Ginger is one of the herbal ingredients that can be used to improve the health of silver pompano, because it can stimulate fish health that can be seen through blood profile. This study aims to determine the effect of ginger on the blood profile of silver pompano and get the best dose. This study used a complete randomized design (CRD) method with 4 treatments, namely Control (without the addition of ginger powder), A (addition of ginger powder 3 gr/kg feed, B (addition of ginger powder 3.75 gr/kg feed and C (addition of ginger powder 4.5 gr/kg feed) each treatment was repeated three times. The silver pompano used were 144 fish with an average weight of 18-19 grams which were reared for 14 days with 2 times a day feeding in Teluk Air, Setokok Island, Batam while blood profile observations were made at the Fish Health and Environmental Testing Laboratory BPBL Batam. The results showed a significant effect on red blood cells, hemoglobin, white blood cells, monocyte percentage at a dose of 3.75 gr/kg feed. While for growth there was no real effect, but the highest average was obtained from treatment C with a dose of 4.5 gr/kg feed. Ginger powder as much as 3.75 gr/kg feed gave the greatest effect on the growth of the fish. Keywords: Silver Pompano, Ginger, Feed, Blood Profile
