What Type of Marine Life or Fish Inhabit Lake Michigan?

Lake Michigan has two climate zones, the northern portion, which is colder, and the Chicago/Milwaukee southern portion, which is more temperate. This disparity leads to an environment suitable for a variety of aquatic life and fish, including several edible and game species as well as some you might not expect. Over 100 species of fish are found in the lake. And while the term "marine" technically refers only to sea life, it is popularly used for freshwater species in the Great Lakes as well, perhaps because these lakes are so big they seem like oceans to many.
  1. Game Fish

    • Among the game fish in Lake Michigan are the walleye, which gains lengths of up to 25 inches and weighs from 1 to 5 pounds. Its skin on the back is olive or golden brown to yellow and it is yellowish white on its underside. It is also known as the walleye pike, pickerel or dore, among other names. The muskie is another fighter. Its proper name is muskellunge and it can reach a length of 5 feet and weigh more than 40 pounds. It is noted by dark-colored bars on a light-colored background of silver-green or light brown.

    Good Eating

It is spotted by the dark shades of green to olive to brown on its back and upper sides. It is lighter on its lower sides, turning to a cream or milk white hue on its belly. There are many other edible species in the lake, including several trout and salmon.
