Bull trout redd counts down in Northwest Montana

December 6, 2015Environmental Issues, Newsbull trout, redd countnfpa

Bull trout numbers are down in this year’s survey, but changes to stream flows may account for most of this . . .

Low flows and stream blockages may have contributed to some lower-than-usual spawning results in the annual northwest Montana bull trout survey this fall.

“In some streams, our annual index sections were not accessible to fish due to debris jams, beaver dams or other flow-related conditions, resulting in lower-than-expected counts,” said Tom Weaver, Montana Fish, Wildlife and Parks bull trout specialist in Kalispell. However, he said the overall count indicates numbers of the federally threatened species remain stable in the region.

Bull trout stable in Northwest Montana

This is a more extensive report on the bull trout population than the one posted earlier . . .

The bull trout population remains stable in Northwest Montana, according to state biologists who completed their annual inventory of spawning sites.

Montana Fish, Wildlife and Parks recently released the results of its annual survey of the Clark Fork, Flathead and Kootenai drainages, and the data shows that the bull trout population has not experienced any significant changes, Regional Fisheries Manager Mark Deleray said.

“In FWP Region One waters, bull trout redd numbers appear stable in all basins, being very similar to 10-year averages,” Deleray said. “In each basin, this year’s count may be slightly higher or lower than last year’s, but not significantly different than recent years.”

No surprises in 2014 bull trout redd counts for Northwest Montana

The Region 1 bull trout redd counts are in . . .

Montana Fish, Wildlife & Parks (FWP) Fisheries Field crews have completed the annual inventory of bull trout spawning sites in the Clark Fork, Flathead, and Kootenai drainages, which comprise northwest Montana’s FWP Region One. Experienced observers walk known spawning areas and count the number of spawning nests called redds. Female bull trout excavate a depression in the streambed where she deposits her eggs which are immediately fertilized by a male. These nests, called redds, are typically four to six feet long by three feet wide, or even larger and are easily identified when walking down the stream channel. Redd counts are indicative of the abundance levels of spawning adult bull trout each year. Redd counts are used to assess status and trends in bull trout populations in northwest Montana.

According to Region One Fisheries Program Manager Mark Deleray, there are no surprises in the 2014 bull trout redd counts for the Clark Fork, Flathead, and Kootenai drainages in Northwestern Montana.

“In FWP Region One waters, bull trout redd numbers appear stable in all basins, being very similar to 10-year averages,” says Deleray. “In each basin, this year’s count may be slightly higher or lower than last year’s, but not significantly different than recent years.” Deleray adds that his staff and cooperators put in a significant amount of field time to collect these data every year.

The fisheries angle on Flathead protection

Trout Unlimited is also happy about passage of the North Fork Watershed Protection Act . . .

The Flathead Valley Chapter of Trout Unlimited has long been committed to protecting the Flathead River system, one of the last best strongholds for native bull trout and westslope cutthroat trout. The recent bipartisan support and passage of the North Fork Watershed Protection Act is a major step in the right direction. Hats off to Sens. Jon Tester and John Walsh and to Rep. Steve Daines for working together to protect the North Fork of the Flathead from future mineral and energy development.

Given recent developments with coal mining in the Elk River drainage in British Columbia, and the continued low bull trout population numbers, as evidenced by annual counts of spawning beds, or “redds” in North Fork tributaries, the passage of this act is both timely and necessary.

Biologists agree on bull trout problem, disagree on fix

Bull trout numbers are down due to competition from non-native lake trout in Flathead Lake. There’s some head-butting over the best fix for the problem . . .

Two biologists from two different government agencies agree on one thing — bull trout numbers in the Flathead appear to be stable. But they differ on the future of the native fish.

Montana Fish, Wildlife and Parks biologist Tom Weaver says bull trout redd counts show a stable population over the past 10 years, and some spawning streams in the North Fork, particularly Coal Creek, saw a surge in numbers this year.

Biologists count spawning beds, called redds, each fall to gauge how many adults are returning to streams each year and the overall health of the bull trout population. The higher the count, the more robust the population. This year, biologists counted 225 redds in the North Fork and Middle Fork tributaries, compared to 229 last year and 189 one year earlier. But those numbers pale in comparison to the early 1980s when numbers ranged from 300 to as many as 600 in 1982.

Bull trout redd count stable, but still well below historic average

October 29, 2013Environmental Issues, Newsbull trout, Flathead Lake, Middle Fork Flathead River, Montana Fish Wildlife and Parks, North Fork Flathead River, redd countnfpa

The latest bull trout redd count is in line with recent years, but still well below what it should be . . .

State biologists found 500 bull trout spawning sites in the North and Middle Forks of the Flathead River this fall, indicating about 1,500 trout made the migration from Flathead Lake.

That’s not as good as the early 1980s before bull trout populations in Flathead Lake started to crash, but much better than the 1990s after federal authorities designated the fish a threatened species, according to Montana Fish, Wildlife and Parks spokesman John Fraley.

“We’ve done this count for 33 years,” Fraley said. “It gives us an idea how the bull trout spawners are doing. We’re about 57 percent of what we were in 1980, but well above the lows of the mid-’90s. That’s encouraging to us.”

However, federal officials monitoring bull trout recovery in Flathead Lake say the annual number doesn’t tell the whole story.

Biologists say shrinking bull trout numbers ‘troubling’

November 27, 2011Environmental Issues, Newsbull trout, lake trout, redd countnfpa

Invasive lake trout continue to cause problems for native bull trout . . .

An annual stream survey of native bull trout in the Swan River drainage revealed a continued decline in reproduction, while the number of spawning trout in the North Fork Flathead Basin also fell below average.
