Description

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.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 188 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Title Brown trout depth and ID telemetry in a regulated river section in southern Norway (Rysstad, Otra River)
Funding OTN is a research and technology development initiative headquartered at Dalhousie University, in Halifax Nova Scotia. OTN is funded by the Canada Foundation for Innovation (CFI) and is grateful to have once received funding from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Social Sciences and Engineering Research Council of Canada (SSHRC). OTN is also grateful for the continued support from Research Nova Scotia, and OTN's host institution, Dalhousie University.
Study Area Description No study area description for this project was provided to OTN for publication.
Design Description A wide range of aquatic species are tagged with small electronic transmitters, surgically implanted or attached externally, which can operate for up to 20 years. Acoustic receivers arranged in line on the ocean floor as well as attached to buoys, gliders and large animals (e.g. grey seals) pick up the coded acoustic signals from these tags identifying each tagged sea creature that passes within half a kilometer of the receiver. Data collected by these listening stations are subsequently uploaded to one of many compatible data nodes, adding to the reach of an intercompatible network of networks designed and maintained by the Ocean Tracking Network, producing current and reliable records for every part of the globe. Certain classes of electronic tags and listening equipment (receivers) may also be outfitted or co-located with sensors to measure the ocean's temperature, depth, salinity, currents, chemistry, and other properties.

Sampling Methods

Acoustic tags released.

Study Extent Program started 2020-03-15 and ran until 2020-12-31
Quality Control OTN species names are verified using the World Register of Marine Species (WoRMS). If species names on new data cannot be verified against (a) known valid names in OTN, and/or (b) WoRMs the Data Provider will be notified so they can check they are correct. Names that cannot be placed after checking with WoRMS are, where possible, placed on the basis of other authoritative sources, such as the Fishbase or ITIS; and once completely verified a request will be sent to WoRMS for addition of the verified species name. http://members.oceantrack.org/data/discovery/byspecies

Method step description:

  1. This resource was created by the Ocean Tracking Network Data Centre as a summarized representation of animal presence determined by electronic tagging efforts. Darwin Core (DwC) records were extracted from the OTN database and filtered and summarized according to international agreed-upon standards.
