Review of risks and benefits of Collaboration for Atlantic Salmon Tomorrow’s (CAST) smolt-to-adult supplementation (SAS) experiment proposal (phase 1, 2018- 2022) . : Fs70-6/2018-014E-PDF

"Recent broad-scale declines in marine survival suggest that the most substantial threat(s) to wild Atlantic salmon in eastern Canada are found in the marine environment, and that the resulting high marine mortality is the primary constraint to the recovery of Atlantic salmon populations. Smolt-to-adult supplementation (SAS) has been proposed by Collaboration for Atlantic Salmon Tomorrow (CAST), a multi-stakeholder group, as an activity to circumvent low marine survival and to increase the number of spawners and freshwater juvenile production in the Northwest Miramichi River system (New Brunswick). SAS would be a precedent-setting activity for supplementation of Atlantic salmon populations in DFO’s Gulf region, where populations are showing decline but are not yet at immediate risk of extinction. CAST has developed a SAS Experiment Proposal with the goals of determining if SAS is a functional conservation strategy that can be used to supplement Atlantic salmon populations in situations where conservation objectives are not being met due to high at-sea mortality, and to answer identified scientific knowledge gaps regarding the SAS conservation strategy"--Context, p. [1].
