Conclusion: • Current conservative regulations provide for sustainability of steelhead stocks while allowing for a productive sport fishery. • Harvests remain low. • Size attributes remain within normal variation where assessed. • Current abundances of steelhead in the assessed streams of Alaska appear to be within normal variation • SE streams have remained near average, while SC streams have been more variable but experienced recent above average counts. • Sustainable fisheries, habitat conservation, and maintenance of current stock attributes remains the primary focus.
