Was told by a friend these things are being caught in tributaries up north P.a Was also told there very agressive and heading for the Great Lakes Please tell me this is another fish story

from what i've heard it is not another fish story there is a food store in california importing these fish into the states while they are still alive some are sold there some are shipped to florida a lot of the ones in florida have made their way into the fresh waterways in miami and they are spawning the bad news is they eat anything they can the worse news is they have an air bladder that allows them to breathe out of water for a while if these fish make it into a major american waterway fishing as we know it will end in about 25-35 yrs
