Figure 22. Patterns of adult size (fork length (cm)) over time from selected Oregon coast (top) and Columbia River (bottom) coho salmon populations. Data from ODFW 1991, S. Jacobs 1994b App., S. King 1994 app., and S. Markey 1994 App.
Figure 23. Patterns of adult size (weight(kg)) over time from selected Washington coast (top) and Puget Sound (bottom) coho salmon populations. Fish were caught in river. Data from WDFW 1994a.
Figure 24. Percent of the total run of coho salmon passing over the North Fork Dam (Clackamas River) each month, grouped by five-year periods, 1957-92. Since about 1980, the passage of coho salmon over the dam has changed from a unimodal distribution, centered around November/December, to a bimodal distribution with peaks in September and January. (Cramer and Cramer 1994).
Figure 26. A comparison of fecundity and female size (cm fork length) for late-run Clackamas River coho salmon with other coho salmon populations in British Columbia, Washington, Oregon, and California. (Crone and Bond 1976, Beacham 1982, Cramer and Cramer 1994).
Figure 27. A comparison of egg size (mg) and fecundity for late-run Clackamas River coho salmon with other coho salmon populations in British Columbia, Washington, Oregon, and California. (Fleming and Gross 1989, Cramer and Cramer 1994).
