Catfish (Magur, Singhi)

Floating and sinking feed together
Magur and singhi feed on the pond floor and rarely take floating pellets, so use a sinking feed throughout. Floating feed in a catfish pond mostly goes to waste.
Good practice
- Feed in the evening and at night, when catfish are most active.
- Spread feed over the pond bottom instead of dropping it in one spot.
- Keep the water about 0.75–1 m deep.
- Move to lower-protein feed as the fish approach harvest size.
- Grade the fish by size regularly; larger catfish eat smaller ones.
Mistakes to avoid
- Using floating feed for a bottom feeder.
- Overfeeding, which fouls the bottom and the water.
- Feeding in the heat of midday, when the fish are inactive.
- Too little water exchange in densely stocked ponds.
- Using pellets that break up before the fish find them.
