This is the OBIS extraction of the Ocean Tracking Network and Government of Maine (GoMaine) Maine DMR: Coastal rivers Adult Salmon Stocking, 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=MCS).
Abstract:Bureau of Sea Run Fisheries and Habitat (BSRFH) staff annually release excess captivereared gravid adult Atlantic salmon (Salmo salar) broodstock for augmentation and comparison of current juvenile production from fry stocking. Staff biologists have observed broodstock spawning, documented creation of viable redds by fry trapping, documented juvenile production to the parr lifestage by electrofishing, and trapped emigrating smolts. However, during redd count surveys, BSRFH staff observations suggest approximately 50% of the adult salmon transplanted in a spawning stream are not seen during spawning. It is uncertain if the unobserved adults are being removed from the stream by predators or poachers, or if they are experiencing mortality due to decreased fitness or stress prior to spawning. It is also possible that broodstock are leaving the transplanted stream and spawning in other areas of drainages. Movement of adults outside study reaches potentially confounds wild salmon return estimates, may lead to negative biological interaction with wild conspecifics, and limits agency ability to fully assess juvenile production potential of captive-reared broodstock. Further assessment of the movements and behavior of transplanted broodstock before, during, and after spawning is needed. The objectives of this study are: (1) to document captive-reared gravid adult Atlantic salmon broodstock spawning behavior, locations, and movements within a release stream or in other reaches of a drainage; (2) quantitatively assess juvenile production from in-river spawning of captive-reared broodstock for comparison with production from fry point stocking; (3) document post-spawn movement of kelts; and (4) document post-spawn habitat used by overwintering kelts.

| 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 |
