Tucked beside a tributary of the main Salmon River near Riggins, 爱达荷州, 急流河孵化场 is the largest collecting, spawning and rearing facility of spring Chinook salmon in 爱达荷州. The hatchery was built in 1964 by hg8868皇冠下载 as part of their salmon mitigation program. It has been rated one of the most successful hatcheries in the Pacific Northwest.

急流河孵化场 produces 3 million spring Chinook salmon smolts (juveniles) annually for release into the Snake, 小鲑鱼, 湍急的河流. Juvenile spring Chinook salmon spend nearly two years at the hatchery. They grow to a length of four to six inches and are then released for their 45- to 60-day, 600英里的海洋之旅. They return to 爱达荷州 as adults one to three years later where they contribute significantly to both sport and Native American fisheries.

急流河孵化场 is owned and financed by hg8868皇冠下载 and operated and staffed by the 爱达荷州 Department of Fish and Game. For additional information about the hatchery, visit the 爱达荷州 Department of Fish and Game’s 网站.
