In general, trophy fish (~1 fpp) returned to the fishery at higher proportions than catchable (~2 fpp) or legal sized fish (~ 3 fpp), often making them a more cost-effective choice to achieve the same angler catch rates. While several hypotheses are proposed to explain why small fish fail to return to the creel, without angling effort they remain confounded. Future trout evaluations should focus on finding complementary tools to assess fishing effort and address uncertainty in tag reporting rates. The effect of specific trout stocks was not assessed in this analysis.

  Citation × Citation Citation Abstract Copy Title: Lake Survey of some Lakes in Deschutes and Willamette National Forests, 1954 Abstract -- July, August and September, 1954, sixty-two Cascade Mountain lakes were surveyed by the Oregon State Game Commission to collect basic data necessarily for the future management of existing trout populations. The survey was devoted to the examination of fish populations, recording water temperatures, physical characteristics and obtaining miscellaneous information pertinent to each lake. The authors spent forty-three working days from July 8 to September 9, 1954 conducting the survey and eleven working days repairing equipment and moving camp to new locations. The location and size of lakes varied. The area of the lakes surveyed ranged from 1 to 85S surface acres Elevation ranged from 4,500 feet to 6,400 feet. Thirty-two lakes were located in the Willamette National Forest in Watershed 2 and thirty were located in Watershed 5 in the Deschutes National Forest. Page 3 contains the names of lakes arranged tn alphabetical order. The survey procedure and analysis was identical to the high lake survey of 1953.

  Citation × Citation Citation Abstract Copy Title: A Report upon the Production and Management of Trout in the State of Oregon, with Recommendations for Increased Efficiency Abstract -- This report of the production of trout and the management of the game fisheries resources within the State of Oregon summarizes the observations made during a 5.5-month survey of these conditions extending through the spring and summer of 1934. This survey was financed jointly by the Oregon Game Commission and the Division of Scientific Inquiry, United States Bureau of Fisheries. Inasmuch as this survey was purposely confined to a study of the trout of Oregon, unless specifically stated to the contrary, all statements, criticisms, and recommendations included within this report are applicable only to trout, as it was neither the purpose nor the scope of this survey to include any other game animals.
