OTN Raby Coho Salmon Tagging - Tag Release Metadata

Latest version published by Ocean Tracking Network on Feb 20, 2019 Ocean Tracking Network

This is the OBIS extraction of the OTN Raby Coho Salmon Tagging project, consisting only of the release tagging metadata. i.e. the locations and dates of tagged animal release. If readers are interested in the full source dataset they should refer to the OTN web site (members.oceantrack.org). 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.

No Description available

Title Ocean Tracking Network (OTN)
Funding OTN is a $168-million research and technology development initiative headquartered at Dalhousie University, in Halifax Nova Scotia. Starting in 2008, OTN began deploying Canadian state of the art acoustic receivers and oceanographic monitoring equipment in key ocean locations. These are being used to document the movements and survival of marine animals carrying acoustic tags and to document how both are influenced by oceanographic conditions. OTN is funded by the 'Canada Foundation for Innovation' and the 'Natural Sciences and Engineering Research Council of Canada' with additional support from 'Dalhousie University' and the 'Social Sciences and Engineering Research Council of Canada'.
Study Area Description OTN is a project of the Global Ocean Observing System (GOOS) providing infrastructure to collect comprehensive data on sea animals in relation to the ocean's changing physical properties at strategic locations along the sea floor in 14 ocean regions off all seven continents. OTN data are in the process of being routinely copied to International Oceanographic Data Exchange (IODE) recognized facilities at the Department of Fisheries and Ocean Canada for long term sustainability and to the Ocean Biogeographic Information System (www.obis.org) for public accessibility.
Design Description A wide range of aquatic species - salmon, tuna, whales, sharks, penguins, crabs, and seals, to name a few, are tagged with small electronic transmitters, surgically implanted or attached externally, and 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 are subsequently uploaded to a central database, resulting in current and reliable global records that can be analyzed and applied to many different environmental research efforts. Tags and receivers are also be outfitted with sensors to measure the ocean's temperature, depth, salinity, currents, chemistry, and other properties.

Sampling Methods

Acoustic tags released.

Study Extent Tagging program started in 2012, ending in 2014
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.
