Guest DartonRage2 Report post Posted April 11, 2013 Every spring I see carp at the mouth of the current river. I'm aware that these carp are not the dreaded asian carp that are making everyone nervous. I'm just wondering if these carp are natural to lake superior or if they were somehow introduced accidentally years ago. Either way I'm just wondering what role these fish play in the ecosystem in lake superior? Quote Share this post Link to post Share on other sites
Guest MNR Report post Posted April 17, 2013 The common carp is a native species to both Europe and Asia but has been widely introduced. It is believed that the population in Lake Superior was derived from carp that escaped a small pond near Newmarket, Ontario in 1896 and spread throughout the Great Lakes, although the carp may have entered the Great Lakes from other sources. Carp in Lake Superior typically inhabit the relatively warmer and shallower bays and estuaries of Lake Superior.Carp are generally considered to have a negative effect on native fish populations because they increase the turbidity of the water and uproot vegetation while feeding.
