I always heard carp came from China or at least Asia. No matter where they came from they would have not gotten here through natural migration so I see no reason to call them native. Wild yes, native no.
Sorry Mo I don't mean to rain on your parade. In fact I don't mind fishing for carp from time to time. I have even gave serious thought to participating in your Cagi event.
I am not necessarily a native fish pundit. I just don't see making common carp something they aren't. Right now I don't see any advantage in having common carp in our streams and lakes. The reality of carp in the US is in general people don't care to eat them and they aren't considered a sport fish so not many people target or harvest them.
According to MDC carp of all types are over populated and do damage to our lakes and rivers. Common Carp are natural shufflers and their habit of wallowing destroys vital habitat needed by other fish and cause a lot of silting problems. Because they are extremely over populated they take up way more than their fair share of biomass.
What would be good for carp is if they could grow to their potential size. If this were to happen I can see where they would become popular as sport fish. The problem is since there is no generally accepted use for them and because they are so under-fished and over populated this is unlikely to ever happen.
