Koi fish are one of the ornamental fish that have cultivation prospects that are in great demand. One of the factors that influences koi fish cultivation is stocking density, high stocking density can have an impact on the growth rate and survival of koi fish. Fish density influences cultivation which can cause competition for food and space for fish to move which can affect fish growth. The aimed of this experiment is to determine the optimal stocking density for the growth and survival of koi fish seeds. This experiment used 2 treatments, namely P₁ (stocking density of 200 individuals m²) and P₂ (stocking density of 150 individuals m²). The results obtained in treatment (P₁) with a stocking density of 200 individuals m² were growth in length and absolute weight of 1.32 cm and 3.08 g and survival was 100%. The temperature during the maintenance period ranged from 27-28^oC and the pH during the maintenance period was found to be around 6.5-7.9. It can be concluded that (P₁) with a stocking density of 200 m² is the best treatment for growth in absolute length and weight, survival and water quality during maintenance at a stocking density of koi fish.
