Smolts of wild coho salmon Oncorhynchus kisutch were captured at Yehring Creek, southeastern Alaska, with trough traps as they emigrated from beaver pond rearing areas. Each trap consisted of a fence along the rim of the beaver dam, a trough, an A‐frame to support the trough, and a floating live box connected to the trough by rigid pipe, The traps caused little mortality, cost about US$ 240 each to build, and were easy to install and maintain.
