We used to poisoned the ponds full of carps, goldfish and kois there was barely any natives left beside dogfish and bass. Now some ponds are literally full of natives, including rare longear sunfish. The carps can caused problems by rooting up the bottom of the lake and lowering the water clarity and quality.
 
lol yea invasive carp have never hurt the natural ecosystem, on second thought, they have all but destroyed it. Carp are efficient, prolific and many get larger than a US native can prey upon. Simply do a quick search on this site about invasive species. You will find a big list of potential problems with releasing fish as well as numerous invasives that have destroyed various places. There are many examples of bad introductionexamples of bad introduction made by scientists that used good research to make those decisions that failed. So if our biologists fail so many times, why do aquarists think that a random release will have no consequences at all. However unlikely, you never know how the ecosystem will really react to a new addition. Lets be honest, we rarely know what to expect when we add a new species to one of our tanks

And we still have common carp problems to this day despite of being "naturalized" in Americas for over 100 years. We would set up a carp trap near the dams or culverts and get huge numbers of carps. We would turn off the aerator in the winterkill lakes to just kill most carps to make more room for other gamefish. I'm not too thrilled about the Asian Carps being in Minnesota and somehow an asian carp managed to get past Coon Rapids Dam and was caught in Sartell which I am just 30 miles away from.
 
carp are an extraordinary resilient fish, we have massive issues with them here in Australia with no real solution in sight.

And they always come back after being killed off in winterkill lakes and the lakes that was poisoned.
