rainbow trout, underwater observation, water pattern
The distribution and movement patterns of fingerling rainbow trout stocked into reservoirs in Utah were investigated with · SCUBA observations and by vertical gill netting. For several weeks after stocking, fingerling trout (ca. 80 mm standard length) were strongly oriented to the shore, and selected habitats providing cover. During the underwater observations, no fish were seen below depths of 2 meters. Two weeks after stocking, the fingerlings were most abundant under docks near where they were planted, indicating that dispersal was relatively slow. Jacob's electivity indices for natural substrates in water 0-1.5 meter deep were in sand, gravel, cobble, boulders and inundated vegetation.
