Feature News Release
No. 1 January, 2000 Fish Tales:
Good News About Native Fish Grayling in Montana Rivers This feature news release is the
first in a series of "Fish Tales"
communicating success stories
about native fish conservation
in the U.S. Fish and Wildlife
Service's Mountain-Prairie
Region, which includes the
States of Colorado, Kansas,
Montana, Nebraska, North
Dakota, South Dakota, Utah,
and Wyoming. Articles may be

attractive cousin of the trout freely swam in the Missouri River
above Great Falls, Montana. With a large dorsal fin spotted in red
or purple, pelvic fins striped orange or pink, and looking more like
its whitefish cousin than trout, the arctic grayling is one of the
most beautiful fish in the salmonid family. While the primarily lake-dwelling arctic grayling (called
adfluvial) is more prevalent and has been introduced in lakes as
far south as Arizona, the more rare fluvial arctic grayling inhabits
only clear, northern streams and does not migrate to lakes. The
numbers of these river-dwelling grayling declined in the United
States by the 1980's to only one remaining native population. The wild fluvial grayling, stressed by competition with non-native
fish, drought, and competing uses of river water, managed to
maintain a foothold in the Big Hole River in southwestern
Montana. Outfitters and guides say that clients enjoy coming to
the Big Hole because they can fish for the catch-and-release
grayling, along with the non-native brown, brook and rainbow
trout that may compete with grayling. When the U.S. Fish and Wildlife Service, along with Montana
Fish, Wildlife, and Parks, other federal land managers, and
Montana Power became aware of this drastic decline, they formed
a working group with state universities to identify the threats to
this imperiled species and develop a plan to restore the
population. "The partners got started on conservation efforts as soon as people
realized the population was in trouble," said Lori Nordstrom,
biologist for the Service's office in Helena. "That's a big part of
why our cooperative efforts have been successful." One of the first steps taken was a joint effort by the Service and
Montana Fish, Wildlife, and Parks beginning in 1988 to gather
grayling eggs from the remaining population, with plans to
provide a safety net of hatchery-raised brood stock in case the fish
disappeared in the wild. Eggs were collected for another 3 years. "We could only collect eggs from 3 or 4 fish a year, because the
numbers were so low," said Pat Dwyer, fish biologist for the
Service's Fish Technology Center in Bozeman, which developed
the brood stock. "It was a difficult process as well, finding fish at
the right time in the spring, when it's usually raining and
snowing, when they're ripe for spawning." It took until the mid-1990's to develop a genetically viable brood
stock at the Center, which now maintains the stock at about 200
fish, with another 500 fish as future replacements. In 1990, the
State of Montana began a simultaneous effort by collecting
grayling eggs from the Center stock, and growing fish to be
stocked in the wild. "The fluvial grayling population was in dire straits when we
started this project," said Dwyer. "The State of Montana has been
very active in introducing grayling, and through a lot of effort has
increased the population in the Big Hole River significantly." The
number of grayling in the river has more than tripled from its low
point to the present. Since the project began, over 3,000 fluvial grayling have been
stocked from the Center. Last Spring, the Center moved some of
its grayling to a private lake owned by billionaire Ted Turner, to
act as a wild brood stock; this stock will be ready to spawn in 2-3
years. Other efforts by private property owners and livestock ranchers in
the area have been essential to the fish's success story. At the
request of Montana Fish, Wildlife, and Parks during a serious
drought in 1994, and with the help of wells drilled by the State
and the Service's Partners for Fish and Wildlife program, many
ranchers drawing water from the Big Hole River voluntarily closed
their irrigation canals to protect the fish, drawing ground water
instead. Last summer, the Partners program provided water storage tanks
for the ranchers, to further aid their efforts. Now, during drought
conditions and peak use periods in July and August, the ranchers
can easily draw and store as much water as they need. As a
result, enough water remains in the Big Hole River for grayling to
survive. Landowners and fishermen in the Big Hole drainage have also
formed the Big Hole Watershed Committee and the Big Hole River
Foundation to work on conserving grayling and their habitat, to
help prevent the species from ever becoming threatened or
endangered. The Committee instituted a drought management
plan for the river to further protect these important waters for the
fish and other benefits. "Landowners have been extremely cooperative, and we couldn't
have stabilized the population without them," added Nordstrom. The local chapter of Trout Unlimited has also been very active in
this effort. In addition, other non-profit agencies have been
raising money for this effort -- most recently through the sale of a
poster by Montana artist Monte Dolack, depicting a grayling in
the Big Hole River. Other land management agencies regularly
pitch in funds for grayling conservation. Reestablishing the grayling into other drainages that were part of
its historic native range has also been a success story for the
species. Through an interagency restoration plan spearheaded by
the Fluvial Arctic Grayling Workgroup and finalized in 1995,
research began to assess current habitat conditions in rivers
within the grayling's native range. Within the past 2 years,
thousands of fluvial grayling have been reintroduced into rivers
where the fish and their offspring have the best chance of long-term viability. Reintroduction areas include the Beaver Head
River, Ruby River, north and south forks of the Sun River, and
headwaters of the Missouri River. Biologists are continuing these
efforts, with the goal of establishing self-sustaining populations. "It's been a huge step," said Nordstrom. "We're not out of the
woods yet, but we're well on our way." The U..S. Fish and Wildlife Service is the principal Federal agency
responsible for conserving, protecting, and enhancing fish, wildlife
and plants and their habitats for the continuing benefit of the
American people. The Service manages the 93-million-acre
National Wildlife Refuge System comprised of more than 500
national wildlife refuges, thousands of small wetlands, and other
special management areas. It also operates 66 national fish
hatcheries, 64 fish and wildlife management assistance offices and
78 ecological services field stations. The agency enforces Federal
wildlife laws, administers the Endangered Species Act, manages
migratory bird populations, restores nationally significant
fisheries, conserves and restores wildlife habitat such as wetlands,
and helps State, Tribal, and foreign governments with their
conservation efforts. It also oversees the Federal Aid program that
distributes hundreds of millions of dollars in excise taxes on
fishing and hunting equipment to state wildlife agencies. Return to the Feature Series Table of

The Service placed the fluvial arctic grayling on its "candidate"
list, identifying it as a species in trouble and one that was at risk
of becoming threatened or endangered in the future.
