teelhead and rainbow trout are the same species of fish but live a much different life after hatching. A rainbow trout will stay in freshwater streams while a steelhead will leave freshwater and spend a portion of its life in saltwater until returning to its freshwater spawning grounds to breed.
Being able to identify all the different trout species is difficult enough, but when it comes to trout hybrids, identifying your catch can be even …
As the trout is a predatory fish species, it is equipped with plenty of teeth. Trout have both larger vomerine teeth located on the roof of their mouths and smaller, needle-like teeth along their upper and lower jawlines. Both sets are very sharp and can definitely hurt you.
Splake is a hybrid between lake and brook trout, which means that it resembles both parent species quite a bit. Splake are both smaller and darker than lakers. The splake’s tail isn’t as deeply forked as that of the lake trout, and splake have fewer appendages on their intestinal tract.
While rainbow trouts are true trouts, lake trouts are actually char. Lakers have dark bodies with light spots, while rainbow trout have light bodies with dark Spots. Rainbow trout have a broad, reddish stripe along their lateral line, which lake trouts lack entirely.
