Descripción

This is the OBIS extraction of the Ocean Tracking Network and Norwegian University of Science and Technology (NTNU) OTN Loan - Beiarfjorden, 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=V2LBEIAR).

Abstract:Conflicts between nature conservation and anthropogenic interactions like urbanization, aquaculture, fisheries and recreation in coastal marine ecosystems are common and divisive for communities. In Europe, the increasing use of near-coastal areas for sea cage aquaculture may negatively influence anadromous brown trout (Salmo trutta; a.k.a. sea trout) and Atlantic Salmon (Salmo salar). Salmonids provide important social and ecosystem services in many countries, including Norway. However, during the last 10-20 years, the abundance of both Atlantic salmon and sea trout have declined markedly in many regions. Knowledge about the biology, ecology and habitat use of salmonids is limited and insufficient for successfully planning sustainable coastal developments. “The secret life of sea trout” research program is using acoustic telemetry linked with physiology, stable isotopes and genomics to document marine migrations and habitat use of anadromous brown trout, Atlantic salmon and Arctic charr from several Norwegian fjords. The findings show that sea trout exhibits diverse marine behavior in time and space depending on nutritional state, sex and morphology of the home watercourse. Thus, potential negative impacts from coastal developments may vary among individuals and watercourses. Acoustic telemetry has been used in several estuaries and fjord systems in Norway to document potential conflicts with human influences such as different infrastructure and fish farming. At the same time, habitat use of sea trout has been studied in undisturbed and pristine estuaries at Kerguelen Island to serve as a reference. Results show that estuaries are important transition zones, especially for younger individuals, between the nursery areas in freshwater and feeding grounds at sea. Additionally, during certain times of the year, estuaries may act as an important longer-term habitat, with fish residing there for weeks to months, and sometimes for the whole duration of the summer feeding migration. A consequence of longer-term residency in estuaries is an increased risk of disturbance from boat traffic, industrial development, harbours, local pollution, gravel extraction, and other physical developments that are often located in estuaries.The findings from the projects are used by stakeholders when decisions are made regarding locations of new fish farms and development of infrastructure in coastal areas. The participation of the public in the research project through community consultations has provided educational opportunities for the local communities, especially their youth, and has allowed for exchange of local and scientific knowledge, enriching both communities. The aim of the Beiarfjord project is to further investigate the migratory behaviour of brown trout and Atlantic salmon in a northern fjord system, where the inner part is a marine protected area, while open sea cage fish farming is located in the outer part of the fjord complex.

Descripción del área de estudio No study area description for this project was provided to OTN for publication.
Descripción del diseño 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.

Control de Calidad 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

Descripción de la metodología paso a paso:

  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.
