| Notes | M.S. Thesis. In the first chapter, the author investigated whether it was possible to use scale analysis to tell whether or not a coho salmon was of wild or hatchery origin. It was. “Eighty-two percent of the hatchery and 89% of the wild fish were correctly identified.” (from the Abstract) The author discussed the ratio of wild to hatchery salmon found and proper scale analysis techniques. In the second chapter, the author addressed the relationship of streamflow and the abundance of coho salmon. “I found that for catch in the Siletz River and Tillamook Bay, and for the troll fishery, total flows in the stream during the period of residency of the juveniles correlated significantly with number of adults resulting from these smolts; annual flows also correlated significantly. There was no indication that summer flows determined production of adult fish 2 years later, except for a significant relationship for the Siletz River.” (p.68) |
