Ocean Ecology of Salmon 2011 Presentation

New data presented by Kintama shows that acoustic tagging did not distort the survival of tagged salmon smolts. A comparison of Kintama’s tagging studies in BC (2004-2009), and the Columbia River (2006-2010), showed that there was no change in the metrics of size distribution of acoustic-tagged smolts that were released and subsequently survived to reach distant parts of the POST array. This is excellent evidence that over the size range of smolts tagged (≥13 cm FL) the tag burden does not seriously affect survival and that smolts of different sizes have similar survivals in the first 1-2 months of life after release.
