Steelhead Fishing Efficiency Decline (1952-1977) | Historical Catch Data #1988054 (License: Personal Use)

This bar chart visualizes the catch per unit effort (CPUE) of adult steelhead across selected years between 1952 and 1977, with the highest value (≈0.28) recorded in 1953-54 and the lowest (≈0.02) in 1972-73. CPUE steadily declined over the period, suggesting either population depletion, habitat degradation, or changes in fishing practices. The data underscores long-term trends critical for assessing salmonid stock health and informing restoration efforts.

Used in fisheries science reports, conservation websites, and academic publications to illustrate historical declines in steelhead abundance; targets researchers, policymakers, and anglers seeking data-driven insights into Pacific Northwest salmonid trends.
