Traditional Passive Integrated Transponder receiver stations along the river also record the passage of fish tagged with the technology. The implant sends out an acoustic signal from the fish in a 600-yard radius that biologists can track with a hand-held receiver as they float stretches of river aboard a raft. To help track migration, the Service’s hatchery biologists have enlisted sophisticated tracking technology provided through a two-year National Fish and Wildlife Foundation grant that involves surgically implanting select fish with a transponder when they leave Pyramid Lake. Image Details An acoustic tracking device like the one shown is implanted in Lahontan cutthroat trout to track their migration from Pyramid Lake into the Truckee River. Their goal is to document when and where the fish are spawning, how they’re using the habitat and how fast they’re moving upstream. You’re going to start seeing anglers coming from all over the world for the opportunity to land one.”Ĭollecting new data amidst a record water year has proven both challenging and highly beneficial to the partnering biologists, who are eager to see how the fish are adapting to their first-ever river experience. ![]() “You can fish for brown and rainbow trout anywhere in the country, but these are a dream-of-a-lifetime trophy native fish that belong here and deserve the chance to return to their home. Fish and Wildlife Service and the tribe have done bringing this trout back from the brink of extinction, it’s a great next step that the state is taking to put regulations into place to further protect these fish,” said angling guide Doug Ouellette, who has fly-fished the Truckee’s waters for the past 45 years. “Our agreements with the Service and the tribe to protect this species will help ensure this trout has a home as it moves further up into the Truckee.” “Now that we’ve seen these big trout of up to 20 pounds or more being able to migrate out of the lake, their presence will become an important part of re-establishing them in the river, and will one day give anglers the opportunity to catch a native fish that’s found nowhere else in the world right in their own backyard,” said Jon Sjoberg, chief of fisheries for NDOW. The dam is the first of a series of four man-made Truckee River barriers the fish will encounter when they pass upstream from the reservation that will be remediated by the Service and its partners with improved, natural fish passageways over the next few years. Image Details Pyramid Lake angler Rutilio Sterling Lara holds a freshly-landed 26-inch Lahontan cutthroat trout. “To get them all the way up into the full span of their range one day will be an amazing accomplishment for our hatchery, and something we can all be proud of." “To see these fish we’ve raised from eggs in the hatchery growing to massive sizes in the lake over the past few years and now watching them run up the river has been the most rewarding experience in fish conservation I’ve ever had,” said Roger Peka, a Lahontan National Fish Hatchery fish biologist. Now, federal, state and tribal partners are building on the recovery and unique genetic preservation work by the hatchery to boost the Truckee’s world-class sport fishery with the return of the state fish of Nevada. Angling stories by Gold Rush settlers in the late 1800s told of 60-pound “monster salmon trout” that were abundant in the river.īy 1940, the fish had vanished from the system. Historical records describe an era when native trout migrated more than 120 miles from Pyramid Lake to Lake Tahoe unhindered by man-made barriers or introduced predators. “This year they’re using the high water flows to run even further up into territory they haven’t been documented in since the late 1930s.” “Last year was the first time we observed the cutthroat moving out of the lake and spawning naturally in the lower reaches of river since the hatchery first began raising them from our brood stock in 1995 and stocking them in the lake with the help of the tribe in 2006,” said Lisa Heki, project leader for the hatchery complex. Fish and Wildlife Service’s Lahontan National Fish Hatchery Complex and Pyramid Lake Paiute Tribe have helped the fish, once thought to be extinct, to successfully migrate from Pyramid Lake into the lower Truckee River for spawning.
