How to Control Grass Carp

Stocked in lakes and ponds to control vegetation, the grass carp are sometimes too effective. If grass carp destroy too much of the plant population, it can have a detrimental effect on the pond as habitat for fish and other wildlife. Removing or controlling the grass carp limits the amount of vegetation removed and helps maintain a balance of vegetation and open water.

Things You'll Need

• Fishing tackle
• Archery fishing gear

Instructions

1. Stock the proper number of grass carp. The Langston University suggests stocking between five and 10 grass carp for each surface acre of the lake or pond. Optionally, a stocking level of 15 carp for every acre of plants or vegetation produces results. In either case, do not exceed the recommended stocking limits.

2. Remove grass carp with a hook and line similar to fishing for any species of fish. Use celery or dough balls of mixed with aquatic plants for bait. Fish in shallow water amongst the plants and roots the grass carp feeds on. This is a case where catch and release is not applicable because the goal is to reduce the number of grass carp in the pond. The flesh of the grass carp is considered excellent with a flaky texture and mild taste.

3. Use hunting techniques to eliminate grass carp. Grass carp feed on aquatic plants and its roots in relatively shallow water. Traditionally, specialized archery equipment is used to shoot carp and other shallow water feeding rough fish. The hunter fires an arrow that is tethered to the bow by fishing line. Use the line to retrieve the arrow and, hopefully, a grass carp from the pond.

Tips & Warnings

• Large predator fish, such as bass, prey on smaller grass carp. Don't plant carp under 12 inches of length in ponds containing larger predator fish.

• Stock as few as three grass carp per acre in ponds also used for duck or goose habitat.
