"Revisions to Canada’s Fisheries Act result in a need for a single limit reference point (LRP) and metric of stock status for major fish stocks to be prescribed by regulation. LRPs are triggers for rebuilding plans under the Act, but remain part of precautionary approach harvest strategies where they serve multiple roles. LRPs are principally seen as reference points representing thresholds to states at risk of serious harm, but also often as operational control points in harvest control rules. The Science Sector has identified a need to provide guidance to estimate LRPs and stock status for scenarios that presently do not meet the “one stock, one LRP” requirement and a more general need for guidance on methods to estimate and report both LRP and stock status across the data and knowledge spectrum. To inform this guidance, we reviewed Canadian approaches to operationalizing LRPs and stock status, and conducted a literature review of existing Canadian and international guidance for LRP and stock status estimation"--Abstract, page v.
