My lake is 12 acres and I have a bunch of 6"-12" carp. I have been told they are part of the food supply for my bass, but I think they are causing my water to be a little less clear than what I would like. Is there a way to trap them out or a way to specifically target them with a poison?
Although carp may provide a reasonable food supply for the bass, they are not a good forage species because they can so easily take over.
As for my good friend rmedgar's suggestion of a bow-and-arrow or a .22, I wouldn't really suggest any kind of rifle. The chance of a dangerous ricochet is always there, plus it takes only a very small amount of water to slow any rifle projectile to the point of uselessness. Arrows are far more effective if you can get in range of the carp, but carp are smart, and learn very quickly to stay away from humans.
I not aware of any carp-specific poison.
However, you are very fortunate. Texas is home to North America's very best pond manager -- Bob Lusk. I'd suggest contacting Bob through the website. If you can't get in contact with Bob, send me an PM, and I'll send you his e-mail and cell phone number. Bob can help clean up your pond. He can help you grow the biggest bass possible for your area. Some of his suggestions may be painful, but he is extremely successful at what he does -- if you allow him to do it.
Good luck,
Ken
