Abstract
  • Federal Aid to Fish Restoration Project F-72-R Final Report
  • Biologists have allotted only minor attention to the cutthroat over the years, as evidenced by a lack of published information. Biological characteristics of wild adult populations, essential to management, were virtually unknown on Oregon's major cutthroat streams prior to this study. Hatchery fish were routinely stocked with little knowledge of the fate of the released fish, of their influence on wild populations, or of their contribution to the angler. Another question among biologists was whether management of the spring put-and-take fisheries or the fall sea-run fisheries should be emphasized on coastal streams. To answer these questions the Game Commission began in 1965 , with the aid of federal funds through the Dingell -Johnson Act (Project F-72-R), a research program with the principal objective of determining the most efficient use of hatchery stocks of cutthroat in coastal streams. The Alsea, Siuslaw and Nestucca rivers, spanning an 83-mile length of the central Oregon coast, were selected for study as each sustained important spring and fall fisheries (Figure 1 ). A second objective of the study was to add to the biological knowledge of wild sea-run populations in the rivers through catch sampling, netting and tagging, and other studies.
