Summary
This report describes the guidance of chinook, silver, and blueback salmon, and steelhead and cutthroat trout with various intensities of light in a two-choice experimental raceway using still water. Under these conditions 90% of over 1000 young salmonidae were successfully deflected into a dark alley by means of an angled barrier of light from a variety of sources ranging from high intensity photoflood lamps down to ordinary 100 watt electric lamps and gasoline lanterns. It is recommended that similar studies be made under field conditions.
