Description

This is the OBIS extraction of the Ocean Tracking Network and Department of Fisheries and Oceans Canada (DFO) Using acoustic telemetry to study Endangered Atlantic Whitefish (Coregonus huntsmani) ecology in native and novel habitats., 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=AWF).

Abstract:Atlantic Whitefish persist in one watershed on Earth, the Petite Rivière near Bridgewater, Nova Scotia, and the species is genetically, culturally, and ecologically unique. Despite being one of the first species protected under Canada's Species at Risk Act (SARA) when it came into force in 2003, they remain Endangered. The most prominent threats to their persistence are habitat deterioration due to anthropogenic impacts such as migration barriers and invasive species increasing competition and predation of Atlantic Whitefish. However, the species is so rare and poorly understood that fundamental questions about the ecology of Atlantic Whitefish are still limiting the effective implementation of the SARA recovery program. A subset of 80 captive-bred whitefish reared in the Dalhousie University Aquatron facility was tagged with acoustic transmitters (Thelma Biotel 2MP9 and Innovasea V9-TP) and released into Millipsigate Lake, the Petite Riviere, or the estuary of the river (i.e. below the migration barriers) in spring 2024. Data analysis will focus on changes between range size and depth use of whitefish in the lake and potential migratory movements of fish released in the estuary. Results will help to identify critical habitats, determine whether the species maintains anadromous instincts, and identify migration barriers. Results will also be used to investigate post-release success and make comparisons between several release strategy elements (i.e. location, season, native/novel system). This study will provide the information needed to identify critical habitats and support the effective implementation of a recovery plan to resist the wild extinction of this Nova Scotia endemic species.

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 3,459 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.

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 2024-05-01 and is ongoing
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.
