Fencing

A good concrete fence must be installed to prevent the escape of grass carp into other ponds and ranches, or they may cheat on your property and get out into neighboring farms where they can damage livestock.

Grass carp can be fed live fish and crumbles of wetted rice. The fish can be fed in the morning, afternoon, and evening. Live fish should be provided daily for three to five days. The live fish should be increased gradually as needed.

Harvesting

Selecting harvesting is generally conducted in the early morning and marketed immediately.

Marketing
