Supplement to the pre-season return forecasts for Fraser River sockeye salmon in 2015 .: Fs70-7/2015-028E-PDF

To provide context for the 2015 forecast (DFO 2015), this year’s Fraser Sockeye forecast supplement report focuses specifically on the 2011 brood year for lake-type stocks, and the 2011 and 2012 brood years for river-type stocks (i.e. Harrison Sockeye). This report synthesizes information on the adult migration conditions, escapement and spawner success, fry and their lake rearing conditions, smolt and juvenile migration, and ocean conditions. In addition, stock compositions of the 2011 escapements, 2013 downstream smolt migration, juvenile ocean migration, and 2015 return forecasts are compared to evaluate proportional changes in stock composition through time. The 2014 forecast supplement report (DFO 2014b) can be used, in combination with this report, to provide context for the five year olds returning in 2015 (DFO 2015).
