The Bull Trout is indigenous to Western North America. Once
hailed as the greatest of all Salmonids, it began a quick
decline in the 1930's. Early naturalists had this to say about
the fish: Bull Trout are by far the most active and handsome of
the trout, they live in the coldest, cleanest and most secluded
waters. No higher praise can be given to a Salmonid than to say,
it is a charr(sic). Indeed they are an aggressive and worthy
game fish. And because of their desire for the coldest and
cleanest water, they are a great indicator species. A whole
watershed's health can be measured by its indigenous population
of bull trout.
Once common in Montana, Idaho, Washington and Oregon, as well as
Alberta and British Columbia, it has now declined so much as to
be put on the endangered species list. Of course human
degradation of the environment is much to be blame. But at least
as big a factor is introduced species. The Bull Trout was
considered an enemy of the Rainbow Trout, because of their
predatory nature, so as Rainbows were introduced, catching and
keeping of Bull Trout has been encouraged.
The Bull Trout can be highly mobile, often migrating back to
lakes that form the headwaters of streams, or even into
different streams altogether. Coastal streams will have
populations that migrate to the ocean and then back. Often times
in the same stream will be stationary and migratory Bull Trout.
This migratory ability has undoubtedly aided the diversity and
thereby the prosperity of the species.
Besides their beauty and fighting abilities. Bull Trout are also
known for their size. River Bull Trout can reach 4 pounds, while
lake dwellers have been caught up to 20 pounds. Perhaps the
saddest part of their recent history is that sportsmen's desires
for other fish, and the official biologists agreeing with this
desire has directly resulted in their perilous status today. It
seems we do a better job today of recognizing entire eco-systems
and appreciating them for what they are. But once we begin to
trigger some species as desirable and others as not, we are
playing with a kind of fire that can burn us for generations.
Native species exist where they exist for a reason, and we
cannot wily nily go deciding we prefer other species to live
there instead.
Bull Trout fry require extremely cold water to survive, because
of this their satisfactory water for spawning beds are minimal.
Which further complicates their recovery rate. Luckily
biologists throughout their entire range are attempting to
protect valued spawning beds, and awareness of them are being
raised. The wonderful thing about nature is she seems to be
awfully forgiving about sins of the past.
With constant vigilance the Bull Trout species will survive,
thriving however remains questionable. Already gone in
California, those of us fortunate enough to live near waters in
their natural range would do well to see what programs exist to
further enhance their survival. And the extra fortunate might
even live near a healthy population, where the can go drift a
Muddler Minnow in front of a hungry specimen and see, touch and
photograph one close up.
