This is the OBIS extraction of the Ocean Tracking Network and University of St. Andrews (St And) Spatial Ecology of spurdog (Squalus acanthias) in a Scottish loch system., 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=LESPUR).
Abstract:Recent anthropogenic pressures including overfishing, climate change and habitat destruction have directly caused the global extinction of several marine species including chondrichthyans (sharks, skates, rays and chimeras). Overall chondrichthyan extinction risk is substantially higher than for most other vertebrates, due to their typical ëK strategistí life history characteristics; slow growth, late age of sexual maturity, low fecundity, long life spans and well-developed offspring making them vulnerable to over exploitation and average global exploitation rates often exceed the rebound rates for many species. In many ecosystems elasmobranchs (sharks, skates and rays) fulfil the role of top level predators, the loss of predators often risks wider ecosystem degradation and can act as a herald for marked changes within ecosystems. Therefore, improved management of elasmobranch populations is needed urgently to ensure the future stability and recovery of marine ecosystems with functional top predators. Despite the wide-ranging behaviour of some elasmobranchs, it has been shown that many species make use of the same areas repeatedly either in the form of site fidelity or residency. The incorporation of such behaviours into the management plans for mobile species may allow for strategies such as Marine Protected Areas to be used. There is evidence that spurdog (Squalus acanthias) displays seasonal residency within a Scottish loch, Loch Etive, a sea loch on the west coast of Scotland, however, the extent to which this occurs between age and sex classes occurs. This was investigated using a static acoustic array and internally implanted acoustic tags on a range of age and sex classes.

| Описание района исследования | No study area description for this project was provided to OTN for publication. |
| Описание плана выполнения исследований | 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. |

| Контроль качества | 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 |
