Maps show spread of aquatic invasive species over time

By |

The Nature Conservancy has animated how six invasive species have spread across the Great Lakes over time. The group has created six maps that show population increase and spread since the appearance of each species in the Great Lakes basin and beyond. Sea lamprey, the first of the six invasive species to appear in the area, initially showed up in Lake Erie in 1921. The map shows the population of the fish expanding into the rest of the Great Lakes up until present day. Also included in the maps are Asian carp, zebra and quagga mussels, round goby, Eurasian Ruffe and black carp.

By Evan KreagerGreat Lakes EchoAsian carp may be one of the better known of the many aquatic invasive species attempting to make their way into the Great Lakes basin. They are one of the five “usual suspects” recognized by The Nature Conservancy in a public awareness campaign. Big head and silver are the most common types of carp, having been spotted in 18 different states, according to The Nature Conservancy. Big head carp can grow up to 60 inches and weigh over 100 pounds. Silver carp are a bit smaller, with a length of about 40 inches and a weight of 60 pounds.

The Nature Conservancy has named the round goby one of the five “usual suspects” invading the Great Lakes basin. Round gobies are native to the Black and Caspian seas, but have found their way into the Mississippi River as well as Lake Michigan. These fish have a heightened ability to sense water movement, allowing them to feed in the dark. Round gobies feed on native fish and their eggs, and have a “blood vendetta” against zebra mussels, according The Nature Conservancy. These gobies can grow up to 10 inches in length and somewhat resemble an overgrown tadpole with black, gray or brown skin.

By Evan KreagerGreat Lakes Echo

The Nature Conservancy has named Eurasian Ruffe, a fish native to northern Europe and Asia, as one of the five “usual suspects” in the Great Lakes basin. This fish has invaded northern Lake Michigan and feeds on native fish eggs. It has sharp spines on its fins making it difficult for predators to catch and eat, giving it the nickname, “Dagger Fin.”

Eurasian Ruffe are generally just under a half a foot in length and have an olive or golden-brown color.
