Recruits-per-Spawner

This indicator provides information on the number of salmon that survive to maturity (recruits) per spawner in the parent spawner generation (brood year). Values below one are highlighted as years when each spawner had fewer than one offspring survive to maturity, and so the Conservation Unit did not replace itself.
