 * __//**The Great Lakes**//__ ﻿have had __//**invasive species**//__ also known as invaders, which are **species that migrate or species that were released into the Great Lakes** who eliminate the other species. By this cause it ruined the balence of the lakes, such as the mosquito larva that is supposed to be eaten by the regular species or edible fish that are suppose to be game for the fishermen but the Invaders lessen the number of fish by hundreds. The sheriffs of the lakes have tried to eliminate or catch and release them back into their old habitat. They also tried to put other species in the lakes to kill off the Invaders, but that back fired and those species ate the original species. Lampreys are the number one reason why most of the orginal species are found dead, because they out breed every other species in the Great Lakes. They give birth to over 50,000 a year and probably even more.
