Canary rockfish (Sebastes pinniger) COSEWIC assessment and status report: chapter 13

Rescue effect

The low biomass levels in U.S. waters to the south reduces the likelihood that these populations could assist recovery of Canadian canary rockfish in the short-term through dispersal of mature adults. However, even a small spawning biomass in these waters may produce a large year class which could spill into Canadian waters. The potential of canary rockfish populations in Southeast Alaska to provide a rescue effect for B.C. populations is uncertain, since status of this population is unknown (Victoria M. O’Connell, pers. comm.).
