Guidance for what you farm
Every species has its own feeding behaviour, density ceiling and temperature range. Start here, then use the calculator for your own numbers.
Indian Major Carp (Rohu, Catla, Mrigal)
Labeo rohita, Catla catla, Cirrhinus mrigala
The backbone of Indian freshwater polyculture. Catla feed at the surface, rohu in the water column and mrigal at the bottom — which is why a floating-plus-sinking feed strategy reaches all three.
3,000–5,000 per hectare · 25–32 °C

Tilapia
Oreochromis niloticus
Fast-growing, hardy and tolerant of high stocking densities — but that density puts real pressure on water quality, so pond conditioning matters as much as the feed.
15,000–25,000 per hectare · 26–30 °C

Pangasius
Pangasianodon hypophthalmus
High-density culture with rapid growth and a strong appetite. Feed conversion is the single biggest lever on profitability here.
20,000–40,000 per hectare · 26–32 °C

Catfish (Magur, Singhi)
Clarias spp., Heteropneustes fossilis
Air-breathing catfish tolerate low dissolved oxygen but need high-protein feed and disciplined bottom management to avoid sludge build-up.

Common Carp
Cyprinus carpio
A bottom-feeding component of most polyculture systems. Responds well to slow-sinking, water-stable pellets that stay intact on the pond floor.
