Fishery managers plan experimental removal of brook trout from High Lake

July 13, 2012

HINES, Ore. – As part of an effort to restore threatened bull trout populations, fishery managers will begin an experimental project later this month to remove brook trout from High Lake in the Strawberry Mountain Wilderness.

From July 23 to Aug. 3, staff from the Burns Paiute Tribe will use a combination of gillnetting, electroshocking, trapping and seining to remove the non-native brook trout.

Brook trout were first introduced into High Lake in the 1930s and are now a naturally reproducing population. Recent surveys show the population is over-abundant, with most of the fish less than 8-inches long and in poor condition. Biologists are concerned, however, that some fish are migrating from High Lake into Lake Creek and hybridizing with native and federally-protected bull trout.

“Our goal this summer is to see whether the mechanical removal of fish can be a successful way to alleviate hybridization pressures downstream,” said Erica Maltz, fisheries manager with the Burns Paiute Tribe.

In addition to mechanically removing fish from the lake, tribal staff also will set a weir above the Lake Creek Youth Camp to trap brook trout trying to migrate into Lake Creek.

Fishing will remain open during removal efforts and there should still be plenty of fish available, according to Shannon Hurn, ODFW district fish biologist. If the brook trout removal efforts are ultimately successful, Hurn said, ODFW plans to offer a new fishing opportunity by restocking the lake with triploid rainbow trout.

The removal of brook trout from High Lake is part of a larger effort to restore bull trout populations in the upper Malheur River basin – an effort that includes the Burns Paiute Tribe, Oregon Department Fish and Wildlife, U.S. Fish and Wildlife Service and the U.S. Bureaus of Reclamation and Land Management. The Tribe also is working with Burns Llama Trailblazers to facilitate movement of gear into the wilderness area.

Lets see...remove one non-native invasive, only to replace it with another?

This is the BEST EFFORT to help out the native Bull Trout?

Remember folks...these "new" fish gotta eat too!!

You gotta love the brain-trusts' of ODFW oldrolledeyes

Triploids can't mate, so there will still be a fishery...?

Real hard to get ALL the brookies without poison...

Wasn't worried about mating...they have to eat.

Competition for the limited available food resources is detrimental to the Bull Trout.

No worries though...they can start eating each other when the bugs and such are gone.

I would think that there is room enough for a relatively smaller number of extra mouths... I thought the problem with the brookies was the sheer number.

I would be interested in hearing how you would set this up. Are there no additional species you would like to see in this lake?

Brook trout in some area's seem to be a mistake made earlier in our history that are hard to fix now....
They populate/overpopulate pretty quickly and the smolt seem to outcompete other species for food.
This is why alot of the local Bio's have been pushing for alot more brookie retention in upper D/ crane. Brookie smolts outcompete redside smolts in the upper D....

Predaceous water beetles.

So, what was there before intervention? What else is there now?

Is there a lot of fishing pressure on the lake?

Evidently boot trout (excuse me, I mean Bull Trout).

That's the problem. The bull trout are native and protected and the brookies are introduced and wiping out the bull trout -- which is amazing considering the bull trout are super carnivorous.

Most high elevation lakes in Oregon contained no fish before the fish and game (it wasn't called the ODF&W) at the time started planting them... or at least, someone did. This lake must be an exception to the norm if it held wild bull trout.

Back in the day...For .50 cents, I could get in to the Saturday Matinee to watch that picture show...it also included a bag of popcorn, soda, peanut M&Ms.

Great times!!

Think the Bulls are in the creek, and the Brookies are invading. There was probably nothing in the lake before the Brookies were intro'd.

This is interesting. The ODF&W is attempting to remove the non-native brookies because they are impacting the native bull trout. Welllllll..... There are native bull trout in Davis. Why is it they are not taking the same steps to remove the non-native, illegally planted LMB from Davis?

Could it be that Native Americans are involved in one fishery and the B.A.S.S. has a lot of pull and might be influencing the ODF&W in regards to wiping out LMB at another fishery?

Nah.

The danger that the brook trout pose to bull trout is not via competition. Neither of them are actually trout; both are char. They are capable of interbreeding, and therein lies the problem. While competition is an important concern, genetic introgression is much more serious. Given the often large populations of brook trout, there is the potential for eventually diluting away the bull trout genes, to the point where all that's left are hybrids that are mostly brook trout. No other species in Oregon presents that same genetic danger to bull trout.
