Results for the 2002 contract period: Objective 1 - Over 1 million juvenile salmon were coded-wire by this program (Table 1). This accounted for about 20% of the fish ODFW coded-wire tagged in 2002 for release in the Columbia Basin; Objective 2 – ODFW recovered and processed over 50,000 snouts collected from coded-wire tagged fish (Table 2); Objective 3 – The survival data summarized below includes results for coded-wire groups funded by this program as well as coded-wire groups funded from other sources; Objective 4 – The last returns of experimental groups of coho marked with VIE tags occurred in 2002 at Sandy Hatchery. This sampling showed that 26 of 67 jack coho and 1 of 2,223 adult coho VIE marked as juveniles retained the VIE mark as adults. Fall Chinook There are three types of hatchery fall chinook released by ODFW in the Columbia basin; Tule, Upriver Bright, and Rogue River stocks. The 10 year average survival of tule stock fall chinook was less than 0.20% for all three programs (Table 3). Ocean recoveries were primarily in West Coast Vancouver Island and Washington coastal fisheries (Table 8). Freshwater recoveries were almost exclusively at hatcheries (Table 9). The 10 year average survival of up-river bright stock fall chinook ranged from 0.05% for Umatilla Hatchery to 0.22% for Bonneville Hatchery fish released at the hatchery (Table 3). Survival of all three up-river bright hatchery programs has been low since the 1987 brood year (Table 3). Ocean catch of up- river bright stock fall chinook was mainly in Alaska, North Central British Columbia, and West Coast Vancouver Island fisheries (Table 8). Freshwater recoveries were mainly at hatcheries, with harvest at about ½ or more of the number of recoveries at the hatchery (Table 9). Percent of recoveries above Bonneville Dam was higher for fish released above Bonneville Dam (Table 9). The 10 year average survival of Rogue River stock fall chinook released at Big Creek and in Youngs Bay was about 0.9% for both programs (Table 3). These fish were caught primarily in Oregon, and secondarily in California and Washington ocean fisheries (Table 8). However, freshwater recoveries were very different for the two groups. Fish released in Big Creek were recovered about 71% at the hatchery, 8% in gillnet fisheries and 16% in sport fisheries (Table 9). Fish released in Youngs Bay were recovered about 9% at the hatchery, 76% in gillnet fisheries and 15% in sport fisheries (Table 9). Spring Chinook A variety of stocks of spring chinook are released by ODFW hatcheries in the Columbia Basin. However, the programs can by grouped by release area; Lower River terminal areas, Willamette Basin, and Above Bonneville Dam. Willamette basin spring chinook stocks are released in Youngs Bay and South Fork Klaskanine River to provide terminal fishery opportunities. The 10 year average survival of these two groups was 0.39% and 0.03% respectively (Table 4). Very few of these fish were caught in ocean fisheries, and most of the freshwater recoveries were in lower river gillnet fisheries (Tables 8 & 9). The 10 year average survival of hatchery spring chinook released in the Willamette basin ranged from 0.43% for McKenzie Hatchery to 0.55% for Marion 1 Forks Hatchery (Table 4). Percent survival was generally greater than 1.0% in the 1987 and 1988 brood years, but has been below 1.0% for all brood years at each hatchery since then (Table 4). In the ocean these fish are primarily caught in Alaska fisheries and secondarily caught in North Central British Columbia, West Coast Vancouver Island, and Washington coastal fisheries (Table 8). Freshwater recoveries are predominately at the hatchery and in sport fisheries, with harvest accounting for 40% to 60% of the total freshwater recoveries (Table 9). Freshwater harvest of Marion Forks Hatchery spring chinook is about 63% of the total freshwater recoveries (Table 9), which may be an artifact of the hatchery adult collection methods. The 10 year average survival of hatchery spring chinook released above Bonneville Dam ranged from 0.01% for fish released in West Fork Hood River to 0.57% for fish released in the Deschutes River (Table 5). Very few of these fish are recovered in ocean fisheries (Table 8). Freshwater recoveries were primarily at hatcheries (Table 9). However, for fish released in the Deschutes River 33% of the total freshwater recoveries were in sport and tribal fisheries (Table 9). Fish released in the Umatilla and Imnaha Rivers had substantial recoveries on spawning ground surveys (Table 9). Steelhead The 10 year average survival of hatchery steelhead ranged from 0.26% for winter steelhead released in the East Fork Hood River to 0.50% for summer steelhead released in Big Canyon Creek on the Wallowa River (Table 6). Ocean recoveries of ODFW Columbia Basin hatchery steelhead are rare (Table 8). The 21 ocean recoveries of steelhead tagcodes covered in this reports were in Alaskan (6), British Columbian (13) and Oregon (2) fisheries. Freshwater recoveries were primarily at hatcheries and fish traps, and secondarily in sport and gillnet fisheries above Bonneville Dam (Table 9). Coho Releases of coho salmon from ODFW hatcheries in the Columbia basin can be divided into three groups by release location; Above Bonneville Dam, At hatcheries below Bonneville Dam, and Terminal areas in the Columbia Estuary. Average percent survival for the last 10 years ranged from 0.15% to 0.38% for releases above Bonneville Dam, from 1.13% to 1.67% for lower river hatchery releases, and from 1.20% to 2.08% for releases in terminal areas (Table 7). Ocean recoveries of coho released in all three areas occurred primarily in Oregon and Washington Coastal fisheries, with smaller catches in California and West Coast Vancouver Island fisheries (Table 8). Although ocean recovery patterns are very similar, freshwater recovery patterns are very different for the three release areas. Coho released in estuary terminal areas are predominantly recovered in lower river gillnet and freshwater sport fisheries, with very few hatchery recoveries (Table 9). Most freshwater recoveries of fish released below Bonneville Dam occur at hatcheries. Freshwater harvest of these fish accounts for 15% to 36% of the total freshwater recoveries (Table 9).
