However, the 2004 abundance is predicted to be higher than the abundance observed in any other prior year back through 1989. Relative to the base period used in scaling the Klamath Ocean Harvest Model (1986-2003), the prediction for 2004 is 2.4-times the average of the estimated actual abundance during this 18-year period; ranging from 24% of their estimated actual abundance in 1987 to 582% of their estimated actual abundance in 1999.

The basis of these estimates are visual counts of adult spawners in randomly selected stream reaches. To date, survey-derived estimates have not been validated against known spawner abundances. Beginning in 1999, we initiated a study at Smith River (Umpqua Basin) to calibrate survey-based spawner estimates. Smith River provides an ideal location for this type of study because it is typical of many other coastal streams that support coho salmon, contains large quantities of habitat and spawners, and provides the ability to efficiently trap and tag adequate portions of the coho run.

  Citation × Citation Citation Abstract Copy Title: OASIS - Use of Stratified Random Sampling to Estimate the Abundance of Oregon Coastal Coho Salmon Abstract -- Management of coho salmon (Oncorhynchus kisutch) in Oregon is heavily dependent upon estimates of the spawning escapement of Oregon coastal natural OCN) coho salmon. OCN coho salmon consist of an aggregate of wild coho salmon populations that originate from Oregon coastal river basins south of the Columbia River and north of Cape Blanco. OCN spawning escapement estimates are an integral component of the management of salmon fisheries in the ocean. Escapement estimates are also used to assess progress towards meeting goals addressed in Oregon's Coho Salmon Plan (ODFW 1982), the Salmon Framework Plan of the Pacific Fisheries Management Council (PFMC 1984), the Oregon Department of Fish and Wildlife (ODFW) Wild Fish Policy, the Oregon Salmon Restoration Plan (Oregon 1997) and various management plans for coastal basins. During 1985-86, the Oregon State University Department of Statistics was contracted by ODFW to review the method used to estimate OCN spawning escapement and to recommend procedures for improving the methodology (Ganio et al.1986). Five sources of bias were identified in the methodology: (1) methods of survey site selection, (2) estimates of the life span of fish in survey sites, (3) counting of nonspawning fish in survey sites, (4) under-counting of fish in survey sites, and (5)estimates of total miles of spawning habitat. The authors concluded that the method of survey site selection was probably the most serious source of bias because of evidence that survey sites were predominantly located in "better than average" spawning habitat. To improve the methodology used to estimate OCN escapement, the authors proposed a sampling plan designed to reduce survey site selection bias and to provide an estimate of the precision of the escapement estimate. The recommended sampling plan incorporated a stratified random sampling (SRS) scheme, where, within geographic 2 sampling units, survey sites are randomly selected from the estimated available miles of coho salmon spawning habitat. Although the SRS survey procedure proposed by Ganio et al. (1986) was a means of vastly improving OCN escapement estimates, more information was needed before this procedure could be adopted. Procedures needed to be developed for selecting and surveying random survey sites (Ganio et al. 1986). The feasibility of incorporating additional levels of stratification to improve the efficiency of the sampling program and account for additional escapement resulting from hatchery fish was needed. More accurate estimates of the available spawning habitat for coho salmon in coastal watersheds were necessary for the development of an effective SRS scheme and ultimately, as a means of improving absolute escapement estimates. Finally, the relationship between spawning densities estimated from the standard coho salmon survey program and spawning densities estimated from a SRS program needed to be determined.

  Citation × Citation Citation Abstract Copy Title: OASIS - Lower Columbia River Coho Status Report 2002 – 2004: Population abundance, distribution, run timing, and hatchery influence. Abstract -- This report provides an assessment of abundance, distribution, spawn timing, and hatchery:wild ratios of spawning adult coho salmon (Oncorhynchus kisutch) based on EMAP spawning surveys in the Oregon portion of the Lower Columbia River in the 2002, 2003, and 2004 spawning seasons. The Oregon portion of the Lower Columbia River Evolutionarily Significant Unit (ESU) extends from the mouth of the Columbia River to the Hood River, excluding areas above Willamette Falls. Analysis is conducted at the population complex level, six subsets of the ESU defined during Oregon Department of Fish and Wildlife Status Review (Chilcote 1999). Population characteristics, most notably the proportion of wild spawners and spawn timing, vary among complexes. Interannual variation within complexes over the last three years is linked to streamflow variation. Most hatchery straying occurred within complex, though the Bonneville complex received strays from further upriver. Abundance increased in areas without evidence of hatchery inputs. Abundance goals established by the ODFW endangered species management plan (Chilcote 2001) in the Clackamas (>1900 adults) and Sandy (>670 adults) have been met the last two years; however, spawner densities and the proportion of wild spawners are lower than on the Oregon Coast.

Status is monitored through spawning surveys. Species or races monitored through these surveys are fall chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch), chum salmon (O. keta) and steelhead (O. mykiss). Assessments cover through the 2001 brood year for salmon and the 2002 brood year for steelhead. Status is generally assessed along two levels of geographic aggregation: Evolutionary Significant Units (ESUs) and Gene Conservation Areas (GCAs) or Monitoring Areas (MAs). ESUs were defined by the National Marine Fisheries Service in conducting reviews for protection under the federal Endangered Species Act. GCAs and MAs are usually subsets of ESUs and were defined by the Oregon Department of Fish and Wildlife either as part of the implementation of the Wild Fish Management Policy or as part of monitoring associated with implementation of the Oregon Plan for Salmon and Watersheds.

Seines and a rotary screw trap were used to capture fish for dye-marking, and residence time within the ecotone was determined for recaptured marked fish. In the lower estuary, ultrasonic transmitters were used to document residence time and patterns of movement for smolts migrating to the ocean. Nearly half of each brood year moved to the estuary as subyearlings. A portion of age-0 juveniles that moved downstream during spring lived in the ecotone through summer for up to 8 months, then most moved back upstream to overwinter. Fish that moved to the ecotone during fall and winter had mean minimum residence times of 48 d in 1999 and 64 d in 2000. Some of the fish that moved to the ecotone during fall and winter moved into an off-channel beaver pond and resided there for a mean of 49 d. Spring age-1 smolts had a mean minimum residence time in the ecotone of 18 d for both years and used recently restored salt marshes and other off-channel habitats. Smolts implanted with ultrasonic transmitters lived in the lower estuary for an average of 5.8 d, during which their direction of movement corresponded to the direction of tidal flow.

Contributions included increased nutrient input to the ecosystem and an additional food source for predators, including bull trout. In addition, the progeny of these adult salmon provided a landlocked chinook fishery in the reservoir and ODFW was able to discontinue annual releases of juvenile salmon reared in ODFW hatcheries (1996). ODFW assumed most of the salmon attempting to leave the reservoir would be killed by various means upon passage through the turbines or regulating outlet. Between 1994-97, ODFW field observations provided circumstantial evidence that some juvenile chinook were surviving passage through the dam. In 1998, we began monitoring juvenile chinook migration out of the reservoir to determine the number, size, age, and mortality rate of fish passing through the turbines and regulating outlet of Cougar Dam.

  Citation × Citation Citation Abstract Copy Title: AI - Rearing of Juvenile Salmon in Recovering Wetlands of the Salmon River Estuary Abstract -- The Salmon River estuary, on the central Oregon coast, provides an excellent opportunity to study salmonid use of restored tidal marsh. The U.S. Forest Service manages the estuary as part of the Cascade Head Scenic Research Area with the goal to rehabilitate the estuary “to its condition prior to the existing diking and agricultural use.” To achieve this goal, the U.S. Forest Service has completed three dike removal projects at 9-year intervals beginning in 1978. These projects created a patchwork of restored marshes in various stages of recovery, providing a natural laboratory for studying marsh restoration processes and their effects on estuarine rearing salmonids. Our Sea Grant-funded research, which is a cooperative study with researchers from the University of Washington, has four objectives: (1) describe salmon species use of undiked reference and recovering marshes; (2) compare diets of juvenile salmon among reference and diked marshes of different recovery ages; (3) compare availability and distribution of prey organisms consumed by juvenile salmon; and (4) assess geomorphological and ecological indicators (“metrics”) of restored wetlands and relationships to salmon use. This report describes the results of fish distribution and abundance surveys. Results of the other objectives are described in Gray et al. (In Review).

This program functions as the landscape link in the overall Oregon Plan monitoring program. Field work for the habitat monitoring program began in 1998 with coordinated site visitations conducted with the two other Oregon Plan monitoring programs; juvenile rearing survey and adult salmon spawning survey programs. The Oregon Plan Habitat Survey program is nested within the Aquatic Inventories Project (AIP). The AIP was begun by the Oregon Department of Fish and Wildlife (ODFW) in 1990 and has expanded to include a wide variety of inventory, modeling and monitoring efforts. The central purpose of these diverse projects is the inventory of physical aspects of the environment that are important for aquatic life and the habitat needs of salmonids and other fishes during the freshwater stages of their life history. Some of the significant ongoing or recently completed projects that are part of the AIP are: Basinwide cesus surveys, Oregon plan Habitat surveys, Restoration Project Monitoring, Salmonid Habitat and Diversity Watersheds Project, Fish Inventories, Great Basin Redband Trout, Oregon Chub Status and Recovery Project, Salmon River Estuary, and Columbia River Estuary Project.
