How to Get Rid of Grass Carp
Grass carp, also known as white amur, are commonly introduced into ponds, lakes and streams to control excess vegetation. They can eat their own body weight in vegetation every day. Grass carp can be genetically engineered so that they can't reproduce. They are generally considered an "all or none" control method--they will eventually devour all the vegetation in a body of water if stocked at a sufficient concentration. Getting rid of unwanted grass carp can be challenging. Does this Spark an idea?

Train the Carp

1
Train the carp to concentrate in a small area. This can be done by periodically and consistently providing a food source, such as fish pellets. The fish will learn to come for food to a certain area at a certain time. You can also use dry dog food, corn or worms as bait.

2
Catch the carp with a net. Use a large throw net or a net that can be pulled rapidly through the concentrated fish. After collecting the fish, train/feed the remaining carp without scaring them for a few days before attempting to net them again.

3
Collect the fish in a fish pen. If you have built or can build a fish pen, train the fish to enter the pen by feeding with fish pellets. Close the pen after it is filled with carp. You can then net the fish individually.
-
4
Use a fish trap. A large fish trap that is kept baited can be useful to remove a large number of carp. Empty the trap every few days. It is sometimes useful to leave a few carp in the trap to attract other carp into the trap.
-
5
Remove the carp. If you are going to transport the live carp to another area, make sure you have a container that is large enough for the number of fish you plan to transport, and is aerated so the fish don't suffocate.

Tips & Warnings
It is almost impossible to remove all the grass carp from a large body of water. Check local regulations (even if you own the body of water) before attempting to remove grass carp.
