KALISPELL (AP) – State wildlife officials are trying to figure out what is killing large grayling in Rogers Lake southwest of Kila.
Regional fisheries manager Mark Deleray tells the Daily Inter Lake that the state Fish, Wildlife and Parks Department started receiving calls about dead grayling washing up on shore about three weeks ago.
He says the fish seem to be succumbing to a white fungus that appears to affect only large, spawning age grayling.
Deleray says a fish health specialist from Great Falls took some samples, but the lab results are not back yet. He says last year's warm summer likely stressed the fish, sending them into the winter in poorer condition than normal.
Deleray notes that bald eagles seem to be enjoying the easy meals.
