BILLINGS, Mont. — The Latest on the discovery of dead fish in the Yellowstone River (all times local):
Montana wildlife officials are finding more dead fish on the Yellowstone River and trying to determine if they were killed because of a parasite that prompted a shutdown of the popular waterway last year.
Montana Fish Wildlife and Parks said its workers found 19 dead mountain whitefish on Thursday in the Paradise Valley upstream of Livingston.
Seventy-nine dead fish, including one trout, had earlier been found downstream of Livingston.
The state shut down a 183-mile stretch of the Yellowstone last year after a disease caused by an invasive parasite killed tens of thousands of whitefish.
Fish, Wildlife and Parks spokesman Greg Lemon says no closures are anticipated this year because the Yellowstone is running colder and higher — conditions that are more favorable for fish.
Montana officials say they recently discovered dead fish in Yellowstone River and are waiting on test results to know if they were killed by the same parasite that killed thousands of fish last year.
The Bozeman Daily Chronicle reports (http://bit.ly/2wBme43 ) Montana Fish, Wildlife and Parks staff found 76 dead mountain whitefish, one dead brown trout and two dead suckers while they were floating on the Yellowstone River between Livingston and Big Timber in southern Montana this week.
According to the news release by the department, biologists do not have enough information to determine the fish’s causes of death and are waiting for test results to come back next week. Regional Fisheries Manager Travis Horton says that staff will continue to look for more dead or dying fish in the river.
