The States of Oregon and Wasington and other fisheries co-managers are engaged in a
substantial review of hatchery management practices through the Hatchery Scientific
Review Group (HSRG). The HSRG was established and funded by Congress to provide
an independent review of current hatchery program in the Columbia River Basin. The
HSRG has completed its work on LCR populations and provided its recommendations.
A general conclusion is that the current production programs are inconsistent with
practices that reduce impacts on naturally-spawning populations, and will have to be
modified to reduce adverse effects on key natural populations identified in the Interim
Recovery Plan. The adverse effects are caused by hatchery-origin adults spawning with
natural-origin fish or competing with natural-origin fish for spawning sites (FCRPS
2008). Oregon and Washington initiated a comprehensive program of hatchery and
associated harvest reforms (WDFW 2005; ODFW 2007). The program is designed to
achieve HSRG objectives related to controlling the number of hatchery-origin fish on the
spawning grounds and in the hatchery broodstock.
Coho salmon hatchery programs in the lower Columbia have been tasked to compensate
for impacts of fisheries. However, hatchery programs in the LCR have not operated
specifically to conserve LCR coho salmon. These programs threaten the viability of
natural populations. The long-term domestication of hatchery fish has eroded the fitness
of these fish in the wild and has reduced the productivity of wild stocks where significant
numbers of hatchery fish spawn with wild fish. Large numbers of hatchery fish have also
contributed to more intensive mixed stock fisheries. These programs largely
overexploited wild populations weakened by habitat degradation. Most LCR coho
salmon populations have been heavily influenced by hatchery production over the years.
Commercial, Recreational, and Subsistence Fishing
Archeological records indicate that indigenous people caught salmon in the Columbia
River more than 7,000 years ago. One of the most well known tribal fishing sites within
the basin was located near Celilo Falls, an area in the lower river that has been occupied
by Dalles Dam since 1957. Salmon fishing increased with better fishing methods and
