Carp in Lakes Good or Bad?

[dgw89]

I had heard from a couple places that carp will sometimes kill off other freshwater fish populations because they eat all the nutrients from the pond. Does anyone know for sure if this can or will happen? I'm asking because my family has some farm ponds in Louisburg that my buddies and i fish pretty often and one of the better ponds has eight carp that were pretty recently put in and i was worried about the effect they will have especially on the bass and catfish populations.
