Idaho Department of Fish and Game crew blocks off a section of stream to electrofish for wild steelhead. Electrofishing is a common survey method used to sample fish to determine what kinds of fish and how many of a given species are in a section of stream. Block nets are temporarily placed on the lower and upper ends of a stream section to keep fish from leaving the area before being sampled.
This sample reach was in the Potlatch River drainage where IDFG crews are monitoring wild steelhead abundance in a place where habitat restoration projects are trying to create better habitat for fish.
