Listed as a threatened species in Michigan. A cold-water fish that needs well-oxygenated water deep in the lake in summer time. Feed on plankton and benthos. They begin eating copepods and small waterfleas and later add bigger waterfleas, midge and ghost midge larvae. Sometimes they feast on mayflies and caddisflies as they "hatch" at the water's surface. Length to 40 cm.

Require cool, well-oxygenated water in the summertime. Spawn in shallow bays during the fall when temperatures drop below 50 degrees F. The lake whitefish is a bottom dweller. So, it eats things that it finds at or near the bottom of the lake. Young whitefish eat waterfleas at first and then begin to include small bottom-dwelling insect larvae. Adult whitefish eat a lot of sideswimmers, fingernail clams, snails, opossum shrimp, midge larvae, and small fish. Length to 60 cm, formerly larger.

GLANSIS

Native to Arctic and North Pacific drainages; accidentally introduced to Lake Superior drainage in 1956. Usually in the upper 20-m of the water column. Pink salmon die after spawning. Young salmon eat sideswimmers, waterfleas, and other small crustaceans. Juveniles and adults in the lake add small fish and opossum shrimp (a crustacean) to their diet. Length to 40-48 cm in Great Lakes. The current MN and PA state records are 2 kg (4.5 lbs).

GLANSIS

Native to Arctic and N Pacific; introduced in the Great Lakes since 1960s to control alewife and provide sports fishing. Little natural reproduction in the Great Lakes, except in Lake Superior - coho die after spawning.. Usually found in the upper portions of the water out to about 10 miles from the shore. While traveling from stream to lake the young coho usually eat copepods and waterfleas. Immature and adult coho eat mostly small fishes, especially smelt and small cisco, but also include opossum shrimp and terrestrial (land) insects. Length to 75-100 cm.

Rainbow trout are stream form, steelhead in the open lake. Found in cool lakes and streams, prefer streams with cobbles, boulders, deep pools and overhead cover. An introduced exotic species native to the West Coast and some of the streams west of the Rocky Mountains. Great Lakes populations (steelhead) were introduced from McCloud Hatchery, California and now reproduce naturally, though they continue to be stocked. Spawn in early spring (sometimes fall and winter) and many live to spawn several times. Young rainbow trout first eat waterfleas and then add aquatic (water) insects, like caddisflies, mayflies, and midges, to their diet. As they grow larger they include small fish, but continue to consume larval and adult insects. They also supplement the diet with other kinds of food, such as snail, leeches, fish eggs, sideswimmers, and algae. Length to 90 cm in steelheads (open lake form); 60 cm in river forms (rainbow). Ohio State Record 20.97 pounds and 36 inches.

The sockeye salmon is native to the Pacific Ocean and streams of the Pacific Northwest, where it is known as the red salmon. Freshwater versions are usually bright silver on the sides, and steel-blue to green-blue on the head and back with no markings or spots. The fish found in the Great Lakes tend to be about 15 to 17 inches long and weigh around 2.5 pounds.

Native to Arctic and North Pacific; introduced in Great Lakes to control alewives and provide sport fishing. Survival of naturally-spawned chinooks is increasing in Great Lakes waters. While living in the parent stream, young chinooks consume a variety of terrestrial (land) and aquatic (water) insects and sideswimmers. After moving to the open lake, they begin to consume a variety of fish, especially smelt and ciscoes. Length to 90-100 cm (to over 140 cm in Alaska). Minnesota's state record for Chinook salmon is 15.1 kg (33 lbs. 4 oz).

Preferred habitat includes headwater spring ponds and small spring-fed streams that have cool, clear waters with sand and gravel bottoms and moderate amounts of vegetation. Spawn each year of their adult life. The food of the young brook trout is mostly small insects. Older fish eat larger invertebrates including many types of aquatic (water) insects, sideswimmers, snails, and worms. They also feed on minnows and other small fishes. Length to 45 cm, rarely larger. The world record is 6.6 kg (14.5 lbs).

2 subspecies - Salvelinus namaycush namaycush (lean lake trout) and Salvelinus namaycush siscowet (fat lake trout). Spawns in fall on rocky reefs. They spend most of their time in the deep water where there is plenty of oxygen and no vegetation. Young lake trout first eat a diet of copepods and waterfleas, then add opossum shrimp. Adult trout eat mostly fish including ciscoes, bloaters, smelt, and cottids. Length to 120 cm, but usually about half that. The PA state record for lake trout is 27 pounds 13 oz.
