The objectives of this study were to analyze the socio-ecological impact and to conduct simple business analysis of tuna (Anabas testudineus Bloch) in a biofloc system. The average public perception was 4.3820, which when compared with the range of Likert score values, is considered high. A high score indicates that the public's perception of biofloc system aquaculture is very supportive. The implication for the climbing perch waste is that the biofloc system can be disposed into the environment and can be used to raise fish and vegetable crops. The total production and equipment costs in this study were Rp8,652,718, with total sales of Rp15.400.000.  The income obtained during one period (7 months) was Rp6,747,282, with an average monthly income of Rp963,897.43. When linked to the 2024 South Kalimantan UMR standard, to achieve an income of Rp3,282,812.11, a minimum of four maintenance ponds with a diameter of 2 meters are required under normal conditions, without disease attacks, and using the high-quality female climbing perch seeds. Therefore, the climbing perch aquaculture using a biofloc system is worth pursuing.  The combined findings from all research suggest that rearing 75-100% female climbing perch fish with a seed size of approximately 7cm in a biofloc system, at a density of 1 fish per 1-2 liters, is technically feasible, economically viable, and environmentally friendly.
