Catfish Stocking Density Calculator
Calculate accurate water volumes, recommended stocking numbers, harvest biomass, and commercial feed bag requirements for **Concrete, Earthen, Tarpaulin (Boga), and Plastic Tank** systems in rectangular or circular dimensions.
Safe stocking range: 426 – 666 fish (Target: ~59.2 fish/m³ or 59.2 fish/m²).
Feeding & Water Management Protocol
- • Pellet Size: 4mm – 6mm
- • Estimated Total Feed: 612.9 kg (approx. 41 bags of 15kg)
- • Target Feed Conversion Ratio: 1.15 FCR
- • Daily Feeding: 2× daily (morning & evening) based on 3% body weight
Maintain continuous fresh water inflow at approximately 9.4 L/min with an unobstructed bottom-draw overflow pipe.
Target Flow Inflow: ~9.4 Litres / Minute
- Feed recommended pellet sizes: 4mm – 6mm. Feed twice daily (morning 7:30 AM & evening 6:00 PM) at 3%–5% of body weight.

Scientific Catfish Stocking Density Rules of Thumb
25–35 table fish per m³ (or 1 fish per 30–35 litres). Requires 50% water exchange every 48 hours to remove toxic ammonia and unconsumed metabolic wastes.
50–70 table fish per m³. Continuous replacement of fresh borehole or stream water prevents organic pollution and supplies steady oxygenation throughout the day.
5–10 table fish per m² of water surface area. Rely on natural phytoplankton and bottom benthic biology. Never overstock without industrial paddlewheel aeration.
