Effects of Carlin tagging on the mortality and growth of sea trout Salmo trutta L.
Main Article Content
Abstract
In the Vardnes river in northern Norway 8375 brown trout Salmo trutta L. smolts and 4352 larger sea trout were captured and tagged when descending and 2248 were tagged when ascending. All migrating fish were tagged individually when they were caught in the traps for the first time. The tagging process reduced the survival rate of the smolts with 17%, while the tagging process had no measurable negative effect on the mortality of the larger-sized trout. Growth of untagged and tagged fish were similar and no effect of tagging on growth-rate was thus recorded.
