Carp (rui, katla, mrigal, silver carp): how much feed per day?
Carp polyculture with supplementary feed such as rice bran and oil cake or pellets.
A Carp (rui, katla, mrigal, silver carp) fingerling of about 10 g eats about 5% of its body weight a day; a fish of 100 g about 5%, and a big fish of 500 g about 3%. For a pond, multiply by the fish's total weight.
Carp (rui, katla, mrigal, silver carp): small fish are fed 2 times a day and larger fish 2 times.
Feeding rate from Bangladesh government guidance (Haor and Wetland Development Department, following Department of Fisheries advice).
Beta: the numbers come from government guidance, published tables and trials, but a fisheries scientist has not checked them yet. Use them as a starting point and confirm with your upazila fisheries officer.

Feeding rate by fish weight
| Average weight | Feed, % of body weight a day |
|---|---|
| 5 g | 5% |
| 20 g | 5% |
| 50 g | 5% |
| 100 g | 5% |
| 200 g | 4.5% |
| 500 g | 3% |
Stocking Carp (rui, katla, mrigal, silver carp)
40–60 fish for 1 decimal (40–60 per decimal)
Dense stocking needs clean water, enough feed and an aerator; stock fewer if you have none.
This is general guidance from published tables and trials, not veterinary advice. For a sick pond, ask your upazila fisheries officer. The tool does not give medicine doses.

Questions farmers ask
How much feed should I give my fish each day?
It depends on how much the fish weigh in all and how big each one is. Small fish eat a larger share of their weight (10–15%) and big fish a smaller share (2–3%). Enter the number and average weight of your fish above to get the amount for today.
How do I find the average weight of my fish?
Catch 10 or more fish with a net, weigh them together, and divide by how many you weighed. The tool does the division in the box marked weigh a few fish together. Do it every 14 days.
Why is the feed less in winter?
Fish eat less in cool water. At 18–21 °C they eat about two thirds as much as in warm water, and under 18 °C about half. Choose the water temperature in the tool.
What is FCR?
FCR is the kg of feed that grew 1 kg of fish. If you gave 900 kg of feed and the fish put on 600 kg, the FCR is 1.5. A high FCR means feed is wasted, and feed is the biggest cost of a fish farm.
Can I trust these numbers?
Where the government gives a figure (the Haor and Wetland Development Department's fish page, which follows Department of Fisheries advice) we use it and say so. Tilapia and pangas feed rates come from published tables. For the rest the rates come from Bangladesh trials and the tool says so. There is no national table of fish inputs like BARC's fertilizer guide, and the Department of Fisheries' advisory forms leave most boxes blank, so you fill in your own prices. Every source is listed on the page.
Is it free? Do I need to sign up?
It is free and needs no sign-up. What you type stays on your phone.
