Description

This is the OBIS extraction of the Ocean Tracking Network and Dalhousie University (DAL) SPG - Atlantic salmon migration, survival and disease, 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=V2LATSLM).

Abstract:Healthy, sustainable Atlantic salmon (Salmo salar) stocks are important economically, ecologically, and culturally to Canada. However, many populations have been severely decreasing since the 1980s, leading to an endangered listing for many populations by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC). Currently, the greatest impacts to their survival have been linked to juvenile survival upon entry into the marine environment. In this Strategic Partnership Grant proposal, we will use acoustic telemetry and cutting edge genomic techniques to address several strategic issues. Firstly, with our partners at Fisheries and Oceans Canada (DFO) and at the Atlantic Salmon Federation (ASF), we will examine the role of naturally occurring pathogens in mediating the migration behaviour and mortality of juvenile salmon in populations throughout the Maritimes, Quebec, and Newfoundland & Labrador. Secondly, we will examine the interactions of wild salmon with aquaculture net-pens throughout the region by quantifying residency patterns, migration pathways, and mortality near net-pens. In parallel, we will characterize pathogen profiles in water samples collected near net-pens, and by opportunistically sampling net-pen escapees, which are frequently caught in a fish-ladder on a river in New Brunswick, we will compare disease profiles of aquaculture and wild salmon in the same river. Thirdly, we will examine the effects of hatchery rearing on the behaviour and survival of juveniles salmon. Hatchery rearing is commonly used for salmon supplementation, and by comparing hatchery and wild fish in the same river, we will explore whether hatchery fish have different susceptibilities to pathogens and altered migration behaviour. Ultimately, we will use the data that we collect from these studies to develop models that examine the degree to which mortality can be explained by aquaculture and/or hatchery operations versus natural environmental variation, and whether these are actually preventing the recovery of Atlantic salmon populations. These issues are of paramount importance to DFO and ASF, given that the Species at Risk Act stipulates that recovery strategies must address the threats identified by COSEWIC.

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 6,698 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.

Title Interactions between migration, marine survival and disease susceptibility in Atlantic salmon
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 2019-04-29 and ran until 2021-05-01
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.
