Test groups of coded‐wire‐tagged yearling coho salmon Oncorhynchus kisutch were either volitionally released or forcibly released for 3 years at two hatcheries. Results for the two release methods showed similar survivals for age‐2 males (jacks) or age‐3 fish. We suggest that volitional release could have benefits in feed savings and allow limited water to be redirected in the hatchery.
