Description
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 13,591 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.
Versions
The table below shows only published versions of the resource that are publicly accessible.

Project Data
The recent decisions to close Atlantic mackerel commercial and bait fisheries in Canada to promote stock rebuilding have drawn attention to knowledge gaps in the species' biology. Electronic tagging of mackerel can have an important role in documenting stock structure and movements and estimating key demographic parameters to enhance understanding of stock status toward more effective fisheries management. Electronic tagging has been used in the provision of fisheries management advice in many jurisdictions. It could provide similar benefits for mackerel if effective methods for handling and tagging the species can be developed. Mackerel are very sensitive to handling and efforts to track them with electronic tagging have been limited. In this project, we will develop tagging protocols using a field pilot in the Northwest Arm to evaluate survival of mackerel and track behaviour within the V2LNASTI array.

| Funding | No funding information for this project was provided to OTN for publication. 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). |
| 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. |

| 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:
- 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.
