Survival and spawning of gill-net-marked red salmon
On Kodiak Island in Karluk Lagoon, 6,253 salmon were tagged in 1953 to determine the effect of gill-net marks for survival and spawning. Approximately half of these fish were gill-net marked and the remainder unmarked (control) fish.

- "The results of the study show that the greatest mortality of new-marked fish occurred shortly after the fish were tagged and released. It is estimated that between 10 and 20 percent of the gill-net-marked fishe escaping from gill nets die from webbing injuries. No difference was noted in the travel time of tagged control and tagged gill-net-marked fish from the lagoon to the spawning grounds. No significant difference was found between the spawning conditions of gill-net-marked fish and the control fish. There was a general tendency for gill-net marks to heal, and no relation was found between the seriousness of the gill-net marks and the survival of the fish."@en

- "Numbered tags of several color combinations were used so that observations could be made on each group of fish both enroute to and on the spawning grounds."@en
