Description
- Abstract: Possible risks of artificial propagation programs have been well documented. Hazards
include disease transfer, competition for food and spawning sites, increased predation,
increased incidental mortality from harvest, loss of genetic variability, genetic drift, and
domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack
and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive
role for wild salmonids by bolstering populations, especially those on the verge of
extirpation, providing a genetic reserve in the case of extirpation, and providing
opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et
al. 1993). The objective of this project is to evaluate the potential effects of hatchery
programs on naturally spawning populations of spring chinook and winter steelhead
within the Upper Willamette River ESU. The project employs four types of activities to
achieve this goal: sampling of returns to hatcheries, creels to assess fisheries,
monitoring of adult and juvenile migration through the use of traps and video
observations, and monitoring natural production through spawning ground surveys.
-
- Purpose: The National Marine Fisheries Service (NMFS) has listed spring chinook salmon
(Oncorhynchus tshawytscha) and winter steelhead (O. mykiss) in the Upper Willamette
River Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species
Act (ESA; 64 FRN 14308; 64 FRN 14517). Concomitant with this listing, any actions
taken or funded by a federal agency must be evaluated to assess whether these actions
are likely to jeopardize the continued existence of threatened and endangered species,
or result in the destruction or impairment of critical habitat. Several fish hatcheries
operate within the ESU and may impact wild populations of listed species. Although all
of the artificial propagation programs that potentially affect listed salmonids in the Upper
Willamette River ESUs are operated by the Oregon Department of Fish and Wildlife
(ODFW), 90% of the funding for these operations comes from the U.S. Army Corps of
Engineers (COE).
