Abstract:Marine survival of Fraser River Chinook salmon stocks has decreased to <1% in recent years and lack of information on downstream and early marine survival hampers their effective management. We conducted a small acoustic telemetry pilot study on 100 Chilko River Chinook that were reared at Chehalis Hatchery B.C. and then transported and released into the Chilko River. The project goals were to estimate freshwater survival, investigate residence timing in the Strait of Georgia, and begin to investigate early marine survival. Because marine acoustic receiver arrays capable of detecting smolts implanted with small 180 kHz acoustic tags only monitor the northern exit from the Strait of Georgia, residence time and early marine survival could only be potentially estimated if smolts migrated north before tag batteries expired five months after ocean entry. Freshwater survival of acoustic-tagged Chinook to the Fraser River mouth (49%) was comparable to other populations or species which migrate the same distance downstream; however, their downstream migration rate 18 km/day) was dramatically slower than that of wild Chilko Lake sockeye, which migrate rapidly to the ocean after exit from Chilko Lake (100-170 km/day). It is unknown whether this behavioural difference is the result of their hatchery origin and transport to Chilko Lake. Only one fish was detected in the Strait of Georgia and none were detected exiting. Combined with the results from trawl surveys, the complete lack of detections in the Discovery Islands and Johnstone Strait suggest that Chilko Chinook do not migrate directly north after river exit. Instead, they likely remain in the Strait of Georgia for at least several months. It is unclear if smolts eventually exited the Strait via the southern route, died during their summer residence, or simply ceased migration to take up residence. An animation of the movements of the Chilko Lake Chinook smolts released in 2016 is available on our website (http://kintama.com/visualizations/).

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
