Abstract:Bureau of Sea Run Fisheries and Habitat (BSRFH) staff annually release excess captivereared gravid adult Atlantic salmon (Salmo salar) broodstock for augmentation and comparison of current juvenile production from fry stocking. Staff biologists have observed broodstock spawning, documented creation of viable redds by fry trapping, documented juvenile production to the parr lifestage by electrofishing, and trapped emigrating smolts. However, during redd count surveys, BSRFH staff observations suggest approximately 50% of the adult salmon transplanted in a spawning stream are not seen during spawning. It is uncertain if the unobserved adults are being removed from the stream by predators or poachers, or if they are experiencing mortality due to decreased fitness or stress prior to spawning. It is also possible that broodstock are leaving the transplanted stream and spawning in other areas of drainages. Movement of adults outside study reaches potentially confounds wild salmon return estimates, may lead to negative biological interaction with wild conspecifics, and limits agency ability to fully assess juvenile production potential of captive-reared broodstock. Further assessment of the movements and behavior of transplanted broodstock before, during, and after spawning is needed. The objectives of this study are: (1) to document captive-reared gravid adult Atlantic salmon broodstock spawning behavior, locations, and movements within a release stream or in other reaches of a drainage; (2) quantitatively assess juvenile production from in-river spawning of captive-reared broodstock for comparison with production from fry point stocking; (3) document post-spawn movement of kelts; and (4) document post-spawn habitat used by overwintering kelts.

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 93 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.

  • Event (core)

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.

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 2010-01-01 and ran until None
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.
