Southern Norway brown trout

Ocean Tracking Network MeasurementOrFact Open in mapper Explore occurrences

This is the OBIS extraction of the Ocean Tracking Network and Dalhousie University (DAL) Southern Norway brown trout, consisting of the release tagging metadata, i.e. the location and date when the tagged animal was released, and summarized detection events of tagged individuals. If readers are interested in the source dataset they may also inquire with the project PIs as listed here or on the OTN web site (https://members.oceantrack.org/project?ccode=SUPERSAT). Abstract:Brown trout were captured in fyke and seine nets in the Rysstad basin in March and April 2020. Fish were instrumented with Thelma 7LP-D tags using the S-256 protocol. Trout were tracked in two arrays in an upstream and downstream area until December 2020. Data are being used for three publications, one on the effects of gas supersaturation on habitat use of trout, one on the effects of macrophyte cutting on trout site selection, and one on the effects of environmental variables on tag detection range.
