MOOSE, WY — Nearly to 200 Jackson Hole Middle School 7th grade students joined Grand Teton National Park, Trout Unlimited, Teton Science Schools and Wyoming Game and Fish biologists at the Gros Ventre Campground on September 24 and 25 to participate in Adopt-a-Trout Field Days.

Despite the rain, students rotated through educational stations conducted by the partners listed above, learning and participating in fish radio tagging, telemetry, water quality monitoring, electro fishing and macroinvertebrate identification.

Participants looked on with fascination while watching biologist surgically implant fish with radio tags, before testing the Gros Ventre River water to see if the tagged fish were going to be released into a healthy environment. Students learned what the tagged fish will eat, how far they might travel, and they took educated guesses as to whether they might move upstream or downstream through the changing seasons.

Jackson Hole 7th graders, with the support of Trout Unlimited and Wyoming Game and Fish officials and volunteers, will monitor life histories of the 35 radio tagged fish for the remainder of the year to see if the removal of the Newbold Dam – a project completed by Trout Unlimited and the National Park Service in the Spring of 2013 – changes the movements of fish in the Gros Ventre River. Biologists hope the dam removal will increase connectivity between the Snake River and upstream habitat in the Gros Ventre drainage for cutthroat trout and other native fish.

The study is funded largely through a grant from the Community Foundation of Jackson Hole to the Grand Teton National Park Foundation.

Did You Know?

Pika with a mouth full of grass

Did you know that pikas harvest grasses so they can survive the long cold winter? These small members of the rabbit family do not hibernate, but instead store their harvest as “haystacks” under rocks in the alpine environment.
