Species guide
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.
- Optimal stocking
- 3,000–5,000per hectare
- Maximum stocking
- 8,000per hectare
- Optimal temperature
- 25–32degrees Celsius
- Typical harvest size
- 800 g – 1.5 kg
- Typical culture period
- 10–12 months
- Feeding zone
- All three zones: catla at the surface, rohu in the column, mrigal at the bottom
Water to aim for

Feeding by growth stage
General starting ranges, as a share of the fish's body weight each day. Adjust to appetite, water temperature and oxygen, and ask your advisor for your own pond.

Floating and sinking feed together
Feed floating pellets first for catla and rohu, where you can watch how much they take, then a sinking feed for mrigal on the bottom. Split the two roughly in line with how much of your stocking is bottom feeders. A floating-only programme leaves mrigal short.
Good practice
- Stock catla, rohu and mrigal at about 40:30:30, then adjust the mix for your local market.
- Feed in the early morning and late evening, when dissolved oxygen is better.
- Use feeding rings or fixed feeding spots so you can see what is eaten and what is left.
- Cut the ration as the water cools in winter; fish eat much less below 22 °C.
- Prepare the pond and build up natural food before stocking.
- Check feed used against growth every few weeks; the FCR calculator makes it quick.
Mistakes to avoid
- Overfeeding, which spoils the water before it grows fish.
- Working out the ration without allowing for water temperature.
- Giving no sinking feed to mrigal and other bottom feeders.
- Skipping pond preparation and natural food development.
- Keeping the same stocking ratio regardless of what sells locally.
