ABSTRACT
The Siamese catfish (Pangasius hypophthalmus) can be cultivated with high stocking density and minimal water usage. The factor influencing fish growth is primarily water quality. The research aims to analyze the Variation of Stocking Density and Water Flow Rate for the Growth and Survival of Siamese catfish Fry (Pangasius hypophthalmus). The study was conducted in Sungai Malang Village, Amuntai Tengah District, North Hulu Sungai Regency, South Kalimantan. The experiment with two different factors can be applied to all experimental units: Factor A (Stocking Density) A1 = Stocking density 1,000 (fish/m3), A2 = Stocking density 3,000 fish/m3, Factor B (Water Flow Rate) B1 = Water flow rate 0 L/second (Control), B2 = Water flow rate 0.1 L/second, B3 = Water flow rate 0.2 L/second. Research Parameters: Absolute weight growth, Absolute length growth, Survival rate, and Condition factor. The influence of stocking density and water flow rate variations on the growth and survival of Siamese catfish fry (Pangasius hypophthalmus), focusing on stocking density (1,000 fish/m³ and 3,000 fish/m³) and water flow rate (control, 0.1 L/second, and 0.2 L/second). The research results show that the combination of stocking density of 3,000 fish/m³ and water flow rate of 0.2 L/second yields the best results in terms of absolute weight and length growth, as well as a higher survival rate. Stocking density variation significantly affects survival rates, while water flow rate does not show the same influence. Condition factors, including survival and growth, are also influenced by stocking density and water flow rate.
