Description
This is the OBIS extraction of the Ocean Tracking Network and University of British Columbia (UBC) Raby Coho Salmon Tagging, 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=NEP.RABY).
Abstract:In August 2012, we conducted a pilot study in the Juan de Fuca strait where we tagged 50 wild adult coho salmon with VEMCO V8 acoustic transmitters (PhD student Raby, technicians Stamplecoskie, Hills, Thompson). This effectively is the first work anywhere on tracking the homeward migration of coho salmon in the marine environment. The fish we tagged were biopsied for DNA and we anticipate that we tagged a mixture of American (Puget Sound) and Canadian (Fraser River) stocks. This project utilized the acoustic receiver lines currently operating in the Juan de Fuca strait, the Fraser River mouth, the lower Fraser River, and likely also an American line operating in Puget Sound (tracking data to be downloaded). The project was a collaboration with industry partners (Area B Seine Society), the Pacific Salmon Foundation, and DFO, with the objective of generating a bycatch mortality estimate for coho salmon captured in purse seine fisheries that target sockeye and pink salmon. As a research platform, we chartered a purse seine vessel and crew, and tagging involved external attachment of V8 tags using Floy Tag "spaghetti" tags. As this was a novel tagging method for migrating adult salmon, we simultaneously conducted a tagging validation study using an on-board net pen with 24-h holding trials. Tagged coho salmon bycatch were also evaluated for injury and reflex impairment in order to link post-release fate with fish condition. Likewise, we were able to compare fish condition with mortality in the on-board 24-h holding study (repeated 4x) in order to bolster our samples sizes for the mortality estimate. In August of 2013, other researchers (PhD students Cook and Drenner, technicians Ward, Hills, Chapman) repeated this study in the same area and with the same crew except with increased sample sizes; 220 coho bycatch were tagged. Unlike in 2012, pink salmon abundances were high and the vessel was chartered to simulate an actual commercial pink salmon fishery. Therefore, mortality estimates from 2013 are likely more realistic than those from 2012. Additionally, longer holding studies (i.e. 3 days and 4 days) were conducted using the same on-board net pen to evaluate progression of disease and stress indices following capture.
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 15,939 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.

| 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 |
