New study: Hatchery-raised salmon are productive
BOISE, Idaho (AP) -- A new study shows that salmon raised in a Nez Perce Tribe hatchery are spawning as successfully in the wild as wild salmon.
Nez Perce Tribe Fisheries Program Manager Dave Johnson told The Idaho Statesman that the study demonstrates how supplementation programs can boost salmon numbers and minimize impact to wild fish populations.
The study, published last week in the journal Molecular Ecology, found that the hatchery salmon from the Johnson Creek Artificial Propagation Enhancement program had the same reproductive success when spawning with wild salmon as wild salmon that spawned together.
The findings run counter to some other research and genetic experiments, which have indicated that hatchery-raised fish are less successful than wild salmon.
