Calibration of visually enumerated Fraser Sockeye spawning populations

In 2014, the Southern Boundary Restoration and Enhancement Fund (SEF) funded the sixth of a multi-year calibration study to minimize bias in visually enumerated Sockeye salmon populations in the Fraser River watershed. Calibration efforts focused on five populations where high precision methodologies were employed; the Birkenhead River, Seymour River, Scotch Creek and the Early and Late Eagle River populations.
