A big and hungry fish is making it's way north from the United States and could pose a threat to the Great Lakes. Asian carp can grow up to 4 feet long and 100 pounds, and it was recently announced that DNA has been found near an electric barrier just south of Lake Michigan. Minister of Natural Resources, Donna Cansfield, says the province is keeping an eye on the fish before it comes to Canada. Crews will be putting a substance called rotenone into the water in the area by the electric barrier to prevent them from creeping up our way. Asian carp gobble up huge amounts of plankton, starving other fish, and even feast on yellow perch and walleye. In a recent update, Ontario Commercial Fisheries Association says if it makes it here, it could be catastrophic for Lake Erie's multi-million dollar fishing industry.
