1 Newfoundland and Labrador Assessment of Atlantic Salmon on Monitored Rivers in 217

2 % Conservation Achieved Science advice & the precautionary approach The precautionary approach is a management framework used to: Identify 3 stock status zones (Critical, cautious, and healthy), Set removal rates within each stock status zone; Adjust removal rates according to stock status, DFO science uses river-specific percent conservation achieved (egg deposition) to provide consistent advice to fisheries managers. 15% % Healthy Zone Cautious Zone Management Target Critical Zone Limit Reference Point (% river-specific conservation): boundary between the critical and cautious zones. The further below the limit reference point a stock is, and the longer time period at that level, the greater the risk of irreversible damage to the population. Upper Stock Reference Point (15% river-specific conservation): above this point populations are considered healthy and available for some predetermined exploitation rate. 2 %
