Abstract:

In view of the problems associated with migrant collection in the forebays of large, deep reservoirs, the scope and scale of research on methods for the collection of young migrants from rivers, streams, and canals above the reservoir have been expanded.  Such studies, if successful, would eliminate the loss of migrants in reservoirs.  Once collected above the reservoir, juvenile migrants could then be safely transported around the dam.  In approaching the problem, we recognized that although young salmon make regular and often precisely timed migrations, the mechanics of the movement and behavior patterns which accompany these migrations are still undetermined.  Young fish obviously respond to particular stimuli.  If nature can supply such stimuli, it would be logical to employ artificial stimuli to guide the young fish into safe routes of passage.  But the questions of choice and techniques and how these should be applied require investigation.  The purpose of this paper is to describe some of these investigations.
