Native Trout:
The cutthroat trout is the real jewel of Yellowstone National Park. Of the four
species of trout, the cutthroat trout is the only native trout. Their are 3 subspecies of
cutthroat trout in the park. The brook trout is technically not a trout. It is a member of
the char family of fish but it is called a trout and considered a trout by fly anglers. It
was stocked at one time in some of the park's streams. The rainbow was also at
one time stocked in the park. The brown trout were stocked in the park as well as
some streams that flow from the park. These brown trout made their way into the
park where they are now plentiful. The arctic grayling and mountain whitefish are
other native species in the park that you may catch on the fly.

Stocked Trout:
We should point out to those of you who that may not know there is a huge
difference in a stocked trout and a wild trout. Stocked trout are feed in a hatchery
prior to being stocked. They are much easier to catch than wild trout that were born
in the stream and have spent their entire life capturing food only from what Mother
Nature has provided. The stocked trout will usually fall for just about anything that
remotely resembles food, especially if it is similar to what they were used to eating
at the hatchery. They are much less afraid of danger than wild trout. Wild trout have
to survive the treats of predators such as otters, birds and other fish their entire life.

Wild (Stream-Bred) Trout:
Like native trout, wild, stream-bred trout are trout that are born and raised in the
stream, not in a hatchery. They are different from native trout in that their ancestors
were at one time stocked. After being stocked, they were able to survive and
reproduce on their own well enough that stocking was discontinued. It is common
to find stream-bred trout in streams and rivers where trout are still stocked, but in
the Yellowstone National Park, stocking was discontinued years ago and the
streams are managed as wild trout streams.
