Intensification of commercial exploitation of chinook salmon in the Columbia River began in Since then, the harvest of chinook salmon can be divided into four phases: Initial development of the fishery ( to ), a period of sustained production with an . habitat and food resources utilized by winter-run Chinook salmon as part of their juvenile outmigration or adult spawning migrations. Central Valley spring-run Chinook salmon were listed as threatened on J (70 FR ). This ESU consists of spring-run Chinook salmon occurring in the Sacramento River . The number of Klamath River fall Chinook salmon returning to the Klamath River Basin (Basin) in was estimated to be: Run Size Age Number Proportion 2 16, 3 46, 4 44, 5 Total , Preseason forecasts of the number of fall Chinook salmon adults returning to the Basin and the corresponding post-season. Late-fall run chinook typically reside in the river to 1 to 3 months before spawning and are adapted for spawning in the reaches of mainstem rivers that remain relatively cold and deep in summer. Winter-run chinook salmon are unique to the Sacramento River and typically wait several months to spawn in .

The only other Chinook salmon hatchery in the basin is a smaller facility operated by the University of Washington (UW) that was founded with Green River origin Chinook salmon in (HSRG ). At this hatchery, approximately of the – returning adults in – were spawned (J. Wittouck, hatchery manager, personal. In , NOAA Fisheries adopted a plan to recover Sacramento River winter-run Chinook salmon, as well as Central Valley spring-run Chinook salmon, and Central Valley steelhead. State and federal agencies, public organizations, non-profit groups and others in California’s Central Valley have formed strong partnerships to save Sacramento River. We developed a hierarchical Bayesian model (HBM) to estimate missing counts of Chinook salmon (Oncorhynchus tshawytscha (Walbaum in Artedi, )) at a weir on the Kogrukluk River, Alaska, between and The model assumed that fish passage during a breach of the weir was typical of passage during normal operations. The schedule is Monday-Friday. Minimum of bachelors degree required. Environmental, biological, or science-based degree preferred but not mandatory. Ideal experience would be at least 1 year in fisheries, wildlife, or the natural sciences. Basic knowledge and proficiency of biological .

The Alaska Department of Fish and Game (ADF&G) manages the Bristol Bay sockeye salmon fishery to achieve escapement goals for 9 river systems that flow into 5 commercial fishing districts. of the AYK region for which no biological escapement goals exist for Chinook, coho, or sockeye salmon (Brannian et al.

; Menard et al.this volume). The Alaska Depart-ment of Fish and Game (ADF&G) is required to develop escapement goals for salmon as part of their mandate to manage salmon re-sources for sustained yields (ADF&G ). CHINOOK SALMON SCIENTIFIC NAME: Oncorhvnchus tshawvtscha, ("on-ko-rink-us tau-wee-cha") from the Greek word onkos (hook), rynchos (nose) and tshawytscha (the common name for the species in Siberia and Alaska).

COMMON NAMES: King salmon, tyee salmon, Columbia River salmon, black salmon, chub salmon, hook bill salmon, winter salmon, tules and black mouth. Late-run chinook salmon enter the Kenai River after June 30 and spawn in the main stem, principally in the transitional and middle river reaches (Burger et al.

Early chinook runs typically range betw to 27, fish, whereas late runs are betwwith a mean of 58, ( to ) (Hammarstrom ). Before last year, there were spawning goals for some Kuskokwim tributaries, but not the river system. In its review of Kuskokwim chinook escapement, the state lowered goals for three.

Though different methods were used across time and space, GrandTab is the only continuous historical dataset available for California Chinook salmon escapement estimates (Albertson et al. ), and it is the primary source used by fishery management agencies (Carlson and Satterthwaite ).

Fillatre () and Petkovich () document differences between early and late components, but Eggers and Bernard () developed biological escapement goals for total Klukshu sockeye, because (a) they considered the evidence for biologically distinct sub-populations insufficient, and (b) catch could not be separated into early and late.

Four runs of Chinook salmon (Oncorhynchus tshawytscha) with unique life histories spawn in the California Central Valley (CCV) basin (Fisher, ) named after the seasons adults return to spawn, including the endangered winter ento River winter-run Chinook salmon are genetically distinct and exhibit rare life history behaviors across their life cycle.

Historically, fall Chinook salmon spawned over a km distance of the Columbia River, but because of dams (Hanrahan et al. ), they are now largely restricted to a km section of the Hanford Reach (Dauble and Watson ) and the Snake River (Mueller and Ward ; Mueller et al.

Habitat quality has also been affected by altering. dance of in The escapement estimates do not include chinook salmon that are removed from the river for brood stock for the hatchery. In andthe hatchery brood stock was and fish, respectively. Part of the reason for the recent decline in escapement is the declining marine survival (Fig.

This decline in survival. Biological Escapement Goals (BEG) and Sustainable Escapement Goals (SEG) have been established for all major areas and salmon species in the Yakutat Area (Table 1).

Parasite abundance will be determined using a quantitative polymerase chain reaction (QPCR) technique. The total number of Chinook salmon (Oncorhynchus tshawytscha) that escape ocean fisheries and return to streams in California’s Central Valley (CV) to spawn is termed ‘escapement.’ Beginning inmark-recapture carcass surveys were used to estimate Chinook salmon escapement in the lower Yuba River, although methods have varied.
