Do you know the physical differences between Wisconsin’s four species of inland trout?
Brook Trout (Salvelinus fontinalis)
Look for the tell-tale “worm-like” markings, known as vermiculations, on the back and red spots with blue halos. They also have red lower fins with a white leading edge and a noticeably square tail fin. Brook trout length tends to range between 4-12 inches.
Brown Trout (Salmo trutta)
Typically, they are between 10-16 inches and have an overall brown to yellow-brown coloring, with black and red spots.
Rainbow Trout (Oncorhynchus mykiss)
Also known as steelhead on the Great Lakes, they most often have a pink to red lateral stripe in the middle of their body, with many spots and a darker back. They also have a spotted square tail and tend to reach 12-16 inches.
Lake Trout (Salvelinus namaycush)
Lake Trout have a deeply forked tail and white inside of their mouth. They are usually a light green or grey to dark green or almost black with light spots and worm-like markings on their back and sides. Lake trout are also Wisconsin’s largest inland trout species, growing to 20-30 inches.
