Minnesota DNR examines steelhead on the Knife River

The Minnesota DNR’s Lake Superior fisheries team has learned about steelhead trout through genetics. Biological sampling allows the DNR to determine if there’s any diseases with the fish, and the genetics data helps manage future steelhead populations. (Photos by Brian Mozey)

The sun was shining along the Knife River in the Lake Superior area on Monday, April 15. The Minnesota DNR’s Lake Superior fisheries staff drove along the river and parked by a trap that the agency built in 1996.
Since its creation, the trap has been used to catch steelhead (rainbow trout) for further studies on the population and spawning process of this fish species. DNR staff visit the trap every day during the late winter and early spring to catch these trout and document various characteristics.
