Results of rotary auger trap sampling, lower Stuart River, British Columbia, in April and May 1992 / by G.C. Taylor and M.J. Bradford.: Fs97-4/2211E-PDF
"Rotary auger traps were used in the lower Stuart River to sample migrating juvenile chinook salmon (Oncorhynchus tshawytscha) and sockeye salmon (Oncorhynchus nerka) between 18 April 1992 and 30 May 1992. Peaks in abundance were recorded on May 20 for chinook fry and on April 25 for sockeye smolts. Greater numbers of all salmonids were caught during the nighttime. Most chinook fry were captured migrating close to the shore while sockeye smolts were caught in similar numbers close to the shore and in the main flow of the river. Based on an estimated trapping efficiency of 2.18%, we estimated the population size of migrant chinook fry at 716,000 for the period sampled. Fork lengths for salmonids are also reported as are abundance data for non-salmonid species"--Abstract, page iii.
