Biologists saw declines in large trout on the upper Yellowstone River this spring, the first time biologists have checked in on fish populations since last summer’s parasite-caused fish kill.
Scott Opitz, Montana Fish, Wildlife and Parks’ upper Yellowstone River biologist, said sampling runs in two four-mile river stretches turned up significantly fewer brown trout between 12 inches and 20 inches long this spring. He said the decline in fish in those sizes “looks like it’s maybe around 50 percent.”
