j/k they cant that i know of, anymore then they can stop all flooding etc spreading spieces( as how the walleye got in the North platte river drainage here from colo.
So called no native species is a big thing(-including business here in a few ways( lotsa taxpayer moneys spent to cater to tourists & trout fisherman.)
Latest is stoping the spread of zebra mussels on water craft & burbot(burbot( or ling/freshwater cod)ARE native to waters east of the rockys in wy & Wy( onlike many other fish))- burbot- now intoducted into waters on the western side of the contintional divide- by persons unknowen. Baitfish are also highly regulated here.
Meanwhile the state spends many many millions to stock a varity of mainy non native trout( rainbow ,brook, brown, golden , laketrout)and other non native, intoduced fish species( just 4&1/2 mill to upgrade the hatchery down the road not long ago- they grow mostly rainbows) of non native trout in many areas of the state.
( only The cutthroat trout is a native here( some areas))- most lakes are damed & or manmade here also.
So pretty much- much of the states whole fishery is based on non native species anyway its cut.

Another Non-Native Predator in the Green River Poses Threat to Native Fish

First burbot captured in Green River
below Flaming Gorge Dam
Researchers with the Utah Division of Wildlife Resources recently found something they didn't want to find: a 21-inch burbot in the Green River below Flaming Gorge dam. The fish was captured in July during an electrofishing study the biologists were doing to recover and study endangered fish in the Green and Colorado rivers.
Catch and kill regulation
The Utah Division of Wildlife has placed a 'no tolerance' fishing regulation on burbot in Utah:
- There's no limit on the number of burbot an angler can catch
- Anglers may not release any burbot they catch.
- All burbot must be killed immediately.
The Wyoming Game and Fish Department has similar regulations in place to help combat burbot:
- There's no limit on the number of burbot an angler may harvest in the Green River drainage
- Anglers are encouraged to keep any and all burbot that they catch
- New laws passed in Wyoming look to further discourage the practice of illegally introducing fish. In addition to fines of up to $10,000, anyone convicted of intentionally introducing fish in Wyoming could be hit with countless restitution costs as well as a lifetime loss of hunting and fishing privileges
