Abstract
We developed a portable electric barrier to aid in the capture of adult chinook salmon Oncorhynchus tshawytscha undergoing spawning migrations up a turbid stream in south-central Alaska. In 1981, we tagged and released 157 chinook salmon after diverting them from the main-stem Killey River into a conventional trap with the aid of the electric barrier. On the basis of returns of tagged salmon to Benjamin Creek, a clear-water tributary of the upper Killey River, we estimated spawners in the drainage to number 8,000 fish. Two different statistical approaches to the mark–recapture data yielded similar estimates. Through several modifications of the electric barrier, we were able to reduce mortality associated with the barrier's use.
