Where did these invasive fish come from? They came from Southeast Asia, initially imported with the intent of keeping retention ponds of water therapy facilities clean. Where there were floods, the fish left to the Mississippi Stream system. They shifted to Missouri and Illinois. As the streams between Illinois, Mississippi, and also Missouri are attached, either normally, or through canals, the fish escaped as well as invaded new waters. There is a canal system that connects the Terrific Lakes as well as the Illinois River.
As of 2013, it was found that there are some Oriental carp in the Wonderful Lakes. This has caused worry as they may compete with native fish as well as induce a decline of them. There are lots of species of fish there that are on the jeopardized or endangered listings, and the addition of carp to the Wonderful Lakes can threaten these species even a lot more. As already mentioned, hopping carp startled by the audio of boat electric motors, could create harm to the devices or individuals. This intimidates leisure sporting activities and also watercrafts, whether the boats are privately owned, or leased via advertisement facilities.
