AbstractCoastal cutthroat trout (Oncorhynchus clarkii clarkii) are considered indicators of stream health, yet paradoxically, they often persist in degraded urban watersheds. To evaluate how cutthroat trout perform in a small urban watershed, we compared several indices of fish size and growth in a small, highly urbanized stream in Seattle, Washington (Pipers Creek) with populations from three larger, forested, watersheds in nearby Strait of Juan de Fuca. We used single sample measures like size and relative condition factor (Kn). We also employed mark-recapture data from PIT-tagged fish to compare multiple performance metrics, including von Bertalanffy growth models, and bioenergetic estimates of food consumption (PCmax). The salmon community composition differed dramatically between systems: Pipers Creek was dominated by cutthroat trout (96%), whereas they were a minor component (1%) in the forested streams, which were dominated by coho salmon and steelhead in summer months.
