Pre-season run size forecasts for Fraser River sockeye (Oncorhynchus nerka) and pink (O. gorbuscha) salmon in 2017: Fs70-7/2017-016E-PDF
“The total 2017 forecast of Fraser Pink Salmon ranges from 4 million to 16 million at the 10% and 90% probability-levels, with a median (50% probability level) forecast of 8.7 million. This median forecast is below average (12.4 million). Fraser Pink Salmon forecasts are extremely uncertain given the shifts in enumeration methodology over time, particularly with regards to the recruitment data (changes in escapement and catch methods). Pink Salmon fry abundance in the 2013 brood year was 230 million, which was almost half of the long term average (441 million). This Science Response Report results from the Science Response Process of December 14, 2016 on the Pre-season abundance forecast for Fraser River Sockeye and Pink Salmon returns in 2017. The 2017 forecast relies on methods of past CSAS processes and publications. To support the 2017 Fraser Sockeye forecast, an additional Science Response process occurred on January 17-18 to summarize data and information on fish condition and/or survival from the 2013 spawners and their offspring"--Context, p. 2.
