Hi Ryan, i'm am not a fish biologist, or any scientist. But I have done some reading up on carp, its history, etc...but at the end I comment from an angler's point of view. The point of view that scientists and biologists never seem to take into consideration as an important factor.
Now firstly, some of the dams that I was referring to, do not have a hard bottom. In fact, on the weekend I fished a big dam that has a combination of sand and silt, yet it contains a large population of carp, as well as 8 other species of fish, and the water is very clean.
About the bass thing, how many photos of dead trophy-sized bass have you seen either in the local mags, on local bass websites? or how often do you see ppl taking big bass home to eat or sell? That is why I am generalizing above.
yes, carp are not completely innocent, and alot of dams are overpopulated by them. But they are also not always to blame. Take for example Harties. Carp have been blamed for the condition of the dam as well as the water quality. Yet, we have seen the newspaper reports of raw sewage being "spilled" into the dam via the municipal works near the dam... on a regular basis. And lets not forget the stuff from settlements along the rivers, getting washed down the rivers into the dam. Now harties is being actively netted..... anyway, nothing we as anglers can do about it...
