Raising Catla: The Fast-Growing Surface-Feeding Carp

Catla is the big-headed giant of the Indian major carps and the fastest grower of the three, feeding on plankton near the surface and mid-water. Because it uses the upper pond, it is the natural partner to mid-water rohu and bottom-feeding mrigal in the polyculture that feeds much of South Asia. For a warm-climate pond, catla brings fast growth and large size to the mix.

Is it right for you?

Catla suit a warm-climate pond grower who wants fast growth and large fish, especially in polyculture. It is hardy and productive where the water stays warm.

System & Space

A fertilized warm grow-out pond is the classic system; catla feed the surface and upper water, complementing rohu and mrigal below in polyculture.

Water & Temperature

They are warm-water fish that thrive on the plankton of a fertilized pond; managing pond fertility to grow that plankton is the key task, along with avoiding cold and low oxygen.

Stocking & Feeding

Stock fingerlings, usually in polyculture, and rely on natural surface plankton supplemented with feed; pond fertility drives their fast growth.

Health & Care

Hardy in a well-managed warm pond; the main tasks are fertility, oxygen and water quality, and avoiding overcrowding. Low oxygen at the surface is a warm-night risk.

Harvest & Enjoying Them

Catla grow fast to a large size in months to a year, giving a popular white flesh valued across South Asia.

Getting Started

Set up and fertilize a warm pond, stock fingerlings (ideally with rohu and mrigal), and manage fertility and oxygen.

What Usually Goes Wrong

Neglecting plankton (their food), warm-night oxygen crashes, and cold climates are the usual mistakes.

FAQ

Fastest-growing carp? Among the Indian majors, yes - catla grows quickest and largest.

Where does it feed? Near the surface, complementing rohu and mrigal below.
