Saving Grayling

- The Arctic grayling is a cold-water fish belonging to the trout and salmon family with a distinctive, sail-like dorsal fin. Found in Montana, they depend on cold water to complete much of their life cycle and serve as an indicator species of healthy rivers. This video tells the story of a team of biologists searching for signs of the elusive grayling on a national wildlife refuge in Montana.

Joe Wright reservoir in Colorado has a great population of grayling!
Beautiful fish!
I have been fortunate enough to catch quite a few grayling in Montana they are one of the most beautiful fish I’ve ever seen I hope we can continue to get their population up
Loved this! Watched it for class
Wow. This story needs more coverage. Great stuff. Always great to see conservation success. Greetings from Australia.PP
were trying the same method in michigan where we lost the grayling in about the 1930's stream incubators and finding the right streams in the head waters where they can shelter and not be predated by the brown trout and other species which they found if they put them with brook trout they do pretty good
How is the population now? Thank you for all your good work guys.
Keep up the great work!
We can probably help to create a larger aerobic zone in the lake without the use of power driven aeration. The technique we have developed has allowed salmonids to survive in many lakes where it was not previously possible. This effort would be very personally satisfying to get involved with.
Great video, keep up the great conservation efforts!
Absolutely glorious, some follow up footage would be amazing
Great video.
Reintroduce grayling to michigan!
I worked for Michigan DNR Fish division in the late '80's to early 2000's. In my time we tried to rear them 2 or 3 times. We were able to raise nice size yearlings, but they just didn't survive after they were stocked. I have heard the Fish division is trying a completely different approach at this time. I hope it works as they are such beautiful fish - but I have doubts.
Wonderful
So beautiful and wonderful to see collaboration achieve a best result! Is it not true that Arctic Grayling are being reintroduced in YNP?
great job with the photography! One that has never had a Grayling sparkling on the end of a line has never truly exprienced wilderness or mountain fishing. BTW great job cutting that new channel. You guys get paid to do that? if so I need a new job....
Well , at least we know these guys can write backwards on a piece of glass. Or is it a camera trick? Great presentation anyway, I didn't know the problem existed. Thanks. I learned something important.
Caught one on the ausable last week, perfect clean release, so extinct they are not.
USFW- “We’re trying stuff!”
All around excellent video from how it's assembled to camera work, yet the removal of the beaver dams is questionable. It makes sense to incorporate the many benefits from beaver dams in order to the arctic grayling adaptive management plan, however, I see the possibility of beaver dams blocking potential fish passage. Perhaps it depends on the sorts of channel features/microhabitat and water parameters the artic grayling prefer.
The conservation efforts described here are praiseworthy. Unfortunately this single most important factor for grayling survival is water: maintaining adequate flows and cool temperatures. These efforts have not succeeded in that regard--irrigators dewater the rivers year after year, and climate change exacerbates this situation. Also, note that reintroduction efforts in the Ruby River and other places outside of the Big Hole River have all failed so far.
Not true there is a very strong population of grayling in Odell lake and that is near wise river
@@MtoutdoorsmanSigh: there is a fundamental genetic and behavioral difference between lake dwelling and stream dwelling (fluvial) grayling. If lake dwelling grayling (or their eggs or fry) are stocked in a river, the fingerlings cannot hold their place in the current, and drift downstream until they either settle in a lake or die. So yes, there are stable populations of lake dwelling grayling in Odell, Mussigbrod, and other places. But the river dwelling (fluvial) grayling are nearly extinct.
@@patmunday6361 thats why you don’t put the eggs in the main stream sigh: fish spawn in creeks and areas of the stream that are slower so that is a human error
@@Mtoutdoorsman Stocking eggs with the incubator buckets in Big Hole tribs has not worked either. And yes, fish absolutely spawn in the mainstem of the Big Hole: watch the browns (fall) on their redds around Maidenrock, the 'bows on their redds around Dewey (spring), or the grayling on their redds around Wisdom (spring). Some fish also spawn in tribs, especially the native trout bulls and cutties, but not all. Getting back to grayling, the best route to restoration would be to insure adequate flows in the mainstem from spawning time (April/May) through September.
Irrigators aside, healthy watershed ecology contributes 99.98982 percent to summer stream baseflows. By comparison climate change contributes roughly 0.01018 percent but always gets mentioned instead of watershed health. I wonder why that is. While collecting funds to purchase water rights, it would be productive to support projects such as thinning overstocked forests strategically in order to create healthier watersheds and improve stream baseflows. A healthy watershed will put much more water into the surface aquifer and flatten the hydrograph during the runoff season. By the way, "failure" is the first step towards success.
Too bad the Grayling used the trout spawning beds...... removing them crippled the Grayling population in the long run. Stick to removing the Beavers and invasive Char from the system, or else there won't be any Grayling left.
Music too dramatic otherwise great.
All big trout and carp should be pet food. It honestly pisses me off that nobody cares or probably has zero understanding of ecology.
