Mark Selective Fisheries allow hatchery salmon—“marked” by having their adipose fins removed—to be retained by anglers, while unmarked salmon must be released. This approach, if implemented when necessary to protect stocks of concern, will provide the BC salmon fishery, particularly in the southern coast, a degree of access—to chinook retention that will enable the fishery to survive while at the same time offering almost complete protection to endangered and threatened unmarked stocks.
Wild salmon have the adipose fin intact and in BC, many hatchery fish do too. Any salmon without an adipose fin was hatchery produced. A hatchery retention fishery is possible when the prevalence of hatchery produced marked fish is high and unmarked stocks of concern are low. Release of unmarked salmon guarantees that wild salmon are protected.
