Abstract
A new method of sampling seaward migrations of juvenile Pacific salmon was designed and operated in the lower Quinault River, Washington. This method was used successfully to sample smolts of sockeye salmon (Oncorhynchus nerka), yearling coho salmon (O. kisutch), and fry of chum salmon (O. keta) during 1974. The sampling apparatus consisted of a net with a submersible live tank that was sent rapidly above water to any desired location across the river, immersed, and fished by means of a supporting cable and two driven lines which were operated from one shore. An automobile with gypsyheads bolted to the rear wheels supplied mechanical power and flood lighting of the river during nighttime operation. The apparatus was relatively inexpensive and easy for one person to operate.This publication has 0 references indexed in Scilit:
