The performance of intensive catfish farming is often limited by low dissolved oxygen (DO) levels and inaccurate feeding. This study evaluated the combination of micro-nano aeration (MNA) and time-based automatic feeding on the Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), survival rate (SR), and feed cost per kg of biomass. A completely randomized design was used, with four treatments: K (conventional blower + manual feeding), A (MNA + manual feeding), P (conventional + auto-feeder), and AP (MNA + auto-feeder); each with three replications, for 8 weeks of maintenance. Water quality parameters (DO, temperature, pH, TAN) were monitored daily–weekly. Sample results showed that AP increased DO at 04.00 (4.2→6.8 mg/L), decreased FCR (1.60→1.25), increased SGR (2.6→3.1%/day), and SR (88→95%), and decreased feed cost/kg biomass (Rp24,000→Rp19,500). The combination of MNA and auto-feeder is recommended for intensive ponds with high stocking density.
