For raising the fry in nursery pond, you can stock up to 0.1 to 0.2 million fry per acre pond.

Generally, 2.5 cm fry are raised in the nursery pond, and then you have to raise the fry until they reach around 10 cm length. And finally you can stock them to the main pond.

Stocking in the Main Pond

After raising the fry in the nursery pond, you have to stock them into the main pond. You can stock a total of 25,000 to 30,000 fish in an one acre pond. And the ratio of rui, catla and mrigal can be 30:30:40.

Feeding the Fish

Providing supplementary feeds is very important for commercial catla fish farming. Without providing adequate supplementary feeds, you can’t expect good growth of the fish.

Catla fish generally consume food from the upper level of water. They are natural food lovers and generally eat whatever insects of small plants float on the surface of the water.

But in case of commercial catla fish farming, you have to feed the fish with supplementary feeds. Generally, most of the farmers use ready-made commercial feeds for feeding their fish.

Total amount of feeds depend on the number of fish stocked in the pond. But the general rule is that ‘you have to feed the fish with 5% food daily of their total body weight’.

For example if you have stocked 10,000 fish and each fish weights 20 grams then you have to provide 10,000 grams (10,000×20/100×5) of food daily.

And also consider the mortality rate while determining total amount of food. And it’s recommended to feed the catla fish multiple times in a day rather than all at once.


You can expect to harvest your fish when they reach your desired size. But for better market value, you should wait until each fish reaches at least 1 kg body weight.

You can harvest the fish from pond by using the fishing nets. Generally, the catla fish has very good market demand when they reach about 1 to 2 kg body weight. By the way, harvesting can be done based on the size of the fish and also depending on market demand.


You should not wait after harvesting. And you should send the fish for marketing immediately after harvesting them. Catla fish is very tasty and it has very good market demand, especially in the South Asian countries.
