SALMOTRACK - Electronic tracking of northern salmonides
SALMOTRACK-project is a primary framework that coordinates most activities in northern Norway on electronic tracking of all life stages on anadromous salmonides, with special emphasis on anadromous species (Atlantic salmon, Arctic charr and sea trout). One of the goals of this project is to coordinate the available logistic and equipment in such a way that as many as possible sub-projects can utilize this in order to maximize the synergetic effects and reduce the total cost of the different sub-projects. This is the largest and most complete fish tracking project in Scandinacia on salmonid fishes. By use of electronic tags (PIT-, archival-, radio-, acoustic and satellite pop-up-tags) the project has since 2006 covered almost all life history stages of Atlantic salmon, from juveniles to salmon smolts, postsmolts, returning salmon (fjord), ascending, spawning and overwintering salmon (river), salmon kelts (post-spawners) in river, fjord and open ocean, immature fall running salmon, as well as escaped farm salmon, anadromous Arctic charr and sea trout and silver eels migrating within rivers and fjord system. The main activity for SALMOTRACK in Norway is in the Alta River and Alta Fjord, but the project also involves activities in the Rivers Neiden, Tana, Skibotn, Signaldalen and Orkla. In addition, we also tag salmon in Ireland, Iceland and Greenland. Since 2006, this activity has contributed to two post-doc positions two PhD positions and six master and two bachelor students at the University of Tromsø. In addition, one Japanese post doc and two international PhD-students (Canada and Sweden) are directly involved in the project, as well as several other national (Norwegian Institute for Nature Research, Trondheim, and Institute for Marine Research, Bergen) and international partners (from Canada, USA, Iceland, Ireland, Sweden, Denmark and Finland). The project is supported by external funding from the Norwegian Research Council, Tromsø Forskninsstiftelse (Moen-foundation), the Norwegian Directorate of Nature Management and others.

Project leader of >25 medium and small sized projects supported by the Norwegian Directory of Nature Management, NVE, the County of Finnmark and Troms, NINA and other since 2000 to present, related to migration studies, population ecology, life-history strategies, freshwater and marine ecology of salmonids, parasitology, telemetry, suitability analysis for locations of fish farms, costal zone and watercourse management, EU's water directive, consequence analysis and freshwater fish surveys.
