We assessed the merits of using Floy anchor tags, machine- and hand-implanted coded-wire tags, and modified Carlin or Swedish trailer tags on chinook salmon Oncorhynchus tshawytscha of at least 15 cm in fork length. Tagged and control fish were released into a landlocked lake. Estimated tag-loss rates were low (2–5%) for each of the tags tested. The tags did not appear to have any significant effect on growth and survival of fish in the lake over periods of up to 2 years.
