Approximately 500 Paiute trout inhabited 2 out of 5.3 km of available stream during the summer of 1974. Distribution of fish was determined by mark-recapture, trapping, and visual observations; there was little large-scale movement. Twenty-one fish were transplanted within the stream to an unpopulated section, and 15 were recaptured there after 2 months. During this time, only four fish moved into the donor area of the stream. Transplantation was successful; therefore, habitat quality was probably not inhibiting fish occupation of most vacant stream areas. Slow dispersal of this population of fish appears to be limiting its distribution within the stream.
