Descripción
This is the OBIS extraction of the Ocean Tracking Network and Kintama Research Services (KRS) Mortality, Movements, and Migration Timing of Age-0 Cowichan Chinook Salmon Tagged in the Southern Gulf Islands in Fall 2017, 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.CCSALMON).
Abstract:Similar to other Chinook populations in the Salish Sea, the Cowichan River Chinook population has declined precipitously since the 1990s. Previous studies have tracked Salish Sea populations of Chinook during the winter and fall months and found that juvenile Chinook likely either remain resident in the Salish Sea beyond the time when they were tracked, or suffer very high mortality. In late summer 2017, we tested these hypotheses by acoustic-tagging 80 age-0 wild and hatchery Chinook salmon (>140 mm FL) resident near the outlet of the Cowichan River in Maple Bay and Sansum Narrows. The fish were captured using microtrolling and then released near their capture locations after tagging. Mobile tracking was conducted for 10 days in September after tagging was completed, and sporadically throughout the fall. We will track their migration until spring 2018 with an array of special-purpose, short-term, receivers deployed to the north and south of the capture and release areas and at two harbour seal haul-outs. The existing POST sub-arrays in the Strait of Juan de Fuca, Northern Strait of Georgia, and Discovery Islands will allow us to determine if fish remain the Salish Sea over winter. In addition to the acoustic tag, fish were implanted with a PIT tag which can ultimately be used to estimate smolt to adult survival back to the Cowichan River. Finally, we collected gill and scale samples for genetic stock dentification and to investigate infectious agents that might be present in tagged fish.i

| Descripción del área de estudio | No study area description for this project was provided to OTN for publication. |
| Descripción del diseño | 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. |

| Control de Calidad | 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 |
