Beings that there population just exploded in my pond this year after 10 years with no problems I would say dont do it. I have been trying to get them out since I got the pond and thought they were almost gone then I catch 30 of them yesterday in one spot. Plus its almost like adding another predator to the pond cause they grow so quick and eat so much. They are alot like a 12" bass in what they eat. Ive been catching them on a 1/2 oz rat-l-trap all weekend.
