This is the OBIS extraction of the Ocean Tracking Network and University of British Columbia (UBC) OTN Canada Pacific Sockeye Salmon Tagging Project 2, 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.PSS2).
Abstract:The objective is to assess the speed of outmigration, and location and level of mortality in freshwater and coastal areas, for individual smolts from Chilko Lake, a population situated 750 km inland from the ocean and is the highest elevation rearing lake for sockeye salmon in Canada. In spring 2010, 200 2-yr old juveniles were captured as they initiated their smolt outmigration and surgically implanted with acoustic transmitters. Sentinel acoustic receivers situated near the release site and in the lower Fraser River, and acoustic curtains associated with POST were used to determine travel rates and locales and levels of mortality. Preliminary results indicate that smolts travelled at ~ 1-2 km/h during the initial sections of their migration through turbulent and clear water environments, and final sections, which were turbid and tidally influenced, of the freshwater migration. But they travelled ~ 5 km/h through the expansive fast flowing sections in between. Diel patterns were evident. On average fish reached the ocean in ~ 8 days with a range of 5-17 days among fish. Survival to reach the estuary is estimated at 20-30% and 15-20% to reach the first POST acoustic curtain situated in Northern Strait of Georgia about 180 km from the Fraser River mouth. We await the downloads of the other POST acoustic curtains to assess survival beyond this first acoustic receiver curtain. Of concern is that at present, POST does not have the funding available to download all of its Canadian curtains (e.g. the Queen Charlotte Strait line) and it is unclear when or if this will happen.

| Описание района исследования | No study area description for this project was provided to OTN for publication. |
| Описание плана выполнения исследований | 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. |

| Контроль качества | 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 |
