The Lake Superior Whitefish is the freshwater fish of the subfamily Coregoninae and Ciscoes. Coregoninae contains whitefish from both freshwater and salt water. The whitefish is also one of the three subfamilies in the salmon family Salmonidae. This species of fish are mainly distributed in chilly waters and are very good in taste. They live on or nearer to the seafloor and contain oil only in their livers instead of guts. They require cool and well-oxygenated water in the summer season to grow.
Lake Superior is one of the largest freshwater lakes in the world, having more surface area than any other freshwater lake in the world.

The lake’s whitefishes are sometimes called the ‘Humpback’ because their heads are smaller than the length of their bodies. Their tails are deeply forked and have dark-edges. Typically they are silvery to white in color and have olive to light greenish-brown backs.
The Whitefish eat things from the bottom of the lake because they live nearer to the seafloor. Adult whitefish are used to eating small fishes, snails, shrimps and amphipods. Young whitefish on the other hand, eat microscopic animals and larvae as they are small and are not able to eat what their adults consume.
The whitefish lays its eggs from October to December. In these months, Lake Superior’s shallow water temperature falls below 7⁰C. The whitefish start laying eggs at night over small rocks near the shores of the lake. It comes up to the water surface and releases eggs and sperm. Around 10,000 eggs are laid by the whitefish which then hatch in early spring season. The number of eggs produced depends upon the size of the female fish. Large sized female whitefish can lay around 130,000 eggs in a year.
The chief predators of the young whitefish are burbot, salmon, lake trout and northern pike. These fishes love to eat the young whitefish as they are small in size and relatively easy to catch. The adult whitefish try to save them from humans as they are their biggest predators. Besides humans, the sea lamprey is another nemesis of the adult whitefish.
