In early October, angler Hailey Thomas set a brand new Idaho state catch-and-release report with a 36-inch rainbow trout/cutthroat trout hybrid—generally known as a cutbow. The tank of a fish had a 21-inch girth, and early estimates put it within the 17- to 20-pound vary. According to the story within the Idaho Statesman, Thomas and her household have been fishing on Henrys Lake and having a reasonably gradual day as a result of poor water readability. Just as they have been about to drag anchor and transfer, Thomas’ bait (which wasn’t specified within the article) acquired picked up by the huge hybrid. The earlier report, which got here from the Snake River, measured 30 inches and had been held by angler Ryan Ivy since 2018.
Henrys Lake is a widely known blue-ribbon trout fishery. It’s house to native Yellowstone cutthroats, in addition to brook trout and the cutbows, which extra generally develop to monster proportions than pure pressure trout, at the very least in U.S. waters. Still, measurement potential apart, many anglers are turned off by hybrid fish, predominantly as a result of they’re not pure. Meanwhile, different anglers gravitate to those mashups, however to grasp the rift, you must take a look at the professionals and cons of those fish.
Tiger’s Tale
Tiger trout are a cross between a brown trout and a brook trout. These fish can, actually, happen naturally within the wild, although it’s pretty uncommon. The Driftless areas of Iowa and Wisconsin boast a better abundance of naturally occurring tigers than every other a part of the nation, which is why fly anglers trying to full the U.S. wild trout slam flock to space. Years in the past, in a small Central Pennsylvania fly store, I stared at an image of a tiny wild tiger on the wall. It was one of the vital beautiful trout I’d ever seen with its gold marbling and olive highlights. The picture, nevertheless, was 20 years outdated, and it was the one wild tiger the proprietor had caught in 40 years of casting on Slate Run. These little pure tigers are extremely prized, however they aren’t to be confused with the opposite extra widespread hatchery tigers which many trout snobs detest.
Tigers are simple to fabricate. So simple that many states combine them in with their hatchery rainbows and browns for spring and fall stockings. At a base stage, these fish simply present the possibility to catch one thing completely different and extra distinctive than the run-of-the-mill stocker, however there’s extra attraction than that. Whereas wild tigers would hardly ever exceed 12 inches, hatchery tigers are consuming machines that develop huge shortly. This makes them extra aggressive than different trout, although of us who dislike hatchery fish will let you know they’re simply dumber and assault issues different trout could not. I can attest to that.
To date, I’ve solely ever caught one trout on a mouse fly in broad daylight within the Northeast, and it was a 22-inch tiger. Despite realizing there have been loads of wild browns in the identical run, they weren’t getting fooled by a black chunk of froth skating on the floor whereas the solar was nonetheless up. This status of hybrids being simpler to catch can also be prevalent with tiger muskies—a cross between a pure pressure muskie and a northern pike—however that has by no means been my expertise.
Local Flavors
I’ve caught a handful of pure pressure muskies in my life, however by no means a tiger although I’ve frolicked on lakes and rivers loaded with them. Each of those places was chosen as a result of any person instructed me the tigers in there have been simple. I used to be instructed they simply eat something you throw. Well, they didn’t. While I is probably not satisfied that tiger muskies are simpler, many muskie diehards consider it so fervently they gained’t even get excited once they catch a tiger muskie. Oddly, although, I perceive this perspective, as a result of I really feel the identical about hybrid striped bass—they’re cool, however not as cool as pure pressure salty stripers.
Much of the talk over the value of hatchery-made hybrids merely boils all the way down to location. If I lived inland the place there was no entry to coastal stripers, I’d most likely love hybrid stripers. If tiger muskies are your solely native muskie choice, you is perhaps all in on chasing them. Interestingly, nevertheless, most of Idaho’s cutbows should not a hatchery creation, and pose a real drawback to the ecosystem.
Crossing Guards
By design, hatchery hybrid fish are sterile so they can’t reproduce. They additionally don’t usually stay so long as pure pressure fish. It’s this live-fast-die-young issue that stops most hybrids from harming their environments. As an instance, a handful of stocked tiger trout that find yourself in wild trout water pose minimal risk, as a result of they gained’t spawn, and so they’ll compete with wild fish for meals for a comparatively quick time. This can also be why it’s not unusual for lakes to grow to be fully devoid of tiger muskies inside a couple of years of stocking packages ending.
The cutbows in Henrys Lake the place Thomas lately claimed the brand new report are purposely stocked and sterile to stop breeding. It’s a distinct story, nevertheless, in Idaho’s South Fork of the Snake River.
According to this story within the Lewiston Tribune, printed in 2019, the state of Idaho has been desperately making an attempt to persuade anglers to kill extra rainbow trout within the river. They made the variety of rainbows that may be stored per day limitless. These fish have been implanted a long time in the past, however in contrast to these uncommon tiger trout within the Midwest, the rainbows are hybridizing with the native cutthroat trout at a quick tempo. The mixture of non-native rainbows and rising numbers of extra aggressive hybrid cutbows is now threatening the river’s inhabitants of native pure-strain cutthroats.
The irony right here is that the typical trout fisherman within the West catches and releases, whereas these stocked tiger trout within the East and center America find yourself in pellet people who smoke extra usually. For Idaho to actually make a dent within the Snake’s rainbow and cutbow inhabitants would require an enormous shift in angler perspective. Meanwhile, I let each tiger trout I catch go, as a result of regardless of them being hatchery creations I nonetheless get excited after I stick one and love the thought of them being round.
