Muskrat and Beaver Control in Ponds
Sustained population control is the best damage prevention method available for both muskrat and beaver. Small, stable populations of muskrats and beaver will do little damage. Pond owners should not wait until furbearers become overabundant before initiating control, because by then the damage has been done.
Crayfish in Ponds
When a pond owner discovers that his pond has crayfish, an image of a leaky pond comes to mind, followed by thoughts of how to eradicate them without harming the fish. Without much effort, crayfish can be managed to provide benefits for the pond owner. Having crayfish in a pond can be beneficial. Crayfish burrows rarely cause ponds to leak. Controlling crayfish in established ponds is best done by stabilizing the water level.
Turtles in Ponds
Most pond owners and anglers view turtles as a threat to fish communities in ponds. Such is not the case. Turtles are primarily scavengers, feeding on dead or dying fish and other aquatic organisms. They thus serve to clean the pond more than cause harm, and should not be indiscriminately destroyed.
Frogs in Ponds
Frogs seldom are a problem because bass and other predators usually keep populations low. Bullfrog tadpoles can become a problem in channel catfish-only ponds or minnow ponds because they can become abundant. Excessive numbers of tadpoles can be reduced by seining, and the adults can be eliminated by capturing them during the legal frogging season.
