They are the top of the food chain, and actually have, and do pose a threat to the game fish population wherever they are found. I am not completely certain, but I think they began by taking over at a time when there were many drainage ditches and canals dug, which allowed them to expand into areas previously populated by more desirable spiecies. They have a high tolerance for water with lower oxygen levels and higher temps.I am not even sure where their original range existed, or if they just started out-reproducing other fish types in a broad area. At one time there was a concerted effort to erradicate them by Wildlife Biologists. That was about 40years ago. Don't know what is going on now with their management.
