Salmon escapement is the amount of a salmon population that does not get caught by commercial or recreational fisheries and return to their freshwater spawning habitat.
[1] Estimates of these amount are calculated with statistical analysis using data collected during that particular run season.
These estimations help produce fishing quotas for the return year of the juveniles born for that years run, or can be used to determine the health of a salmon stock.
[3] Biological Escapement Goals (BEGs) are the number of returning salmon that would provide the largest possible amount of take while ensuring that enough salmon will successfully spawn, so that their offspring will replace the harvested amount in future runs.
[4] A BEG model is applied when a fishery harvests salmon in a manner that will allow managers to determine the desired spawning destination for that population of salmon.
