A trap was constructed to catch pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta) fry emigrating through the intertidal reaches of a small nonglacial stream on the Kenai Peninsula in south central Alaska. The trap consisted of two components: the trap frame, which housed the V ‐shaped trap, and the fry collection box. These components floated on sty‐rofoam logs and were connected by a flexible hose. When the tide was high, the trap floated and fished the upper 1.2 m of the water column; when the tide was low, the trap rested on the bottom and fished effectively in 10 cm of water. The gear has functioned properly at 0 C. With three traps, 70,000‐214,000 fry per year have been caught.
