Descrição
This is the OBIS extraction of the Ocean Tracking Network and Norwegian University of Science and Technology (NTNU) OTN Loan - Salmonids in Trondheimsfjorden, 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=V2LTROD).
Abstract:The aim of the Trondheimfjord project is to get better knowledge of marine migrations of anadrome species (Atlantic salmon, Brown trout) from rivers draining to the Trondheim Fjord. The fjord is a national salmon fjord (a kind of MPA), which means that salmon aquaculture is prohibited. But outside the fjord, one of the most intensive areas for open net pen salmon aquaculture in Norway is located.The two overall hypotheses to test are that a) Atlantic salmon only spent few days in the protected fjord system before heading out to the open sea and b) that brown trout stay within the protected fjord system during the whole marine feeding season. Additionally, we will explore in more details the individual migratory behaviour of the tagged fish and related that to physiological status, previous growth rates, sex and body size. The outcome will be crucial knowledge for regional coastal zone planning and will be of high value as background information when the Norwegian traffic light system, which regulate the aquaculture production, will be evaluated in the years to come.
Registros de Dados

| Financiamento | 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. |
| Descrição da Área de Estudo | No study area description for this project was provided to OTN for publication. |
| Descrição do Design | 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. |

| Controle de Qualidade | 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 |
Descrição dos passos do método:
- 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.
