Recombinant growth hormone (rGH) is a product produced by combining genes that are desired artificially (clones) outside the body with the help of cell transformers, in this case growth genes from target fish are isolated and transformed with the help of microbes, such as Escherichia coli, Bacillus, Streptomyces, and Saccharomyces. Utilization of the hormone RGH is to accelerate growth and increase endurance of fish seed. The increase in growth acceleration is triggered by where the hormone rGH will trigger organs associated with growth to increase its growth. The study used a Completely Randomized Design (CRD) with 5 treatments and 3 replications with the volume of water used 30 liters of water and aquarium size 40x30x25 cm ^ 3 each treatment, at a dose of 0 ml / kg (control), 1 mg / kg, 2 mg / kg kg, 3 mg / kg, and 4 mg / kg. The administration of 1 mg/kg, 2 mg/kg, 3 mg/kg, and 4 mg/kg of rGH hormone to commercial feed can affect the growth rate of the discolored wader seed growth. The study is seen in terms of SGR (Specific Growth Rate), Daily Length Growth, SR (Survival Rate) and FCR (Food Convention Rate). The optimal dose for the growth performance of the cakul wader fish seeds. in the treatment of P3 (2 mg/kg), it can be concluded that the higher dose does not necessarily have the effect of increasing high growth. Therefore, the administration of the hormone RGH must be in accordance with the right dose.
