Abstract:
Since 2009, the FISHSCAPE Project (grant number 1719267, 1417754, and 0902153), based at Toolik Field Station, has monitored physical, chemical, and biological parameters within three watersheds: The Kuparuk (including Toolik Lake and Toolik outlet stream); The Sagavanirktok (primarily Oksrukuyik Creek, but also including sections of the Ailish and Atigun Rivers and the Galbraith Lakes); and The Itkillik (primarily the I-Minus outlet stream, a tributary that that feeds into the Itkilik River). Target species were primarily Arctic grayling and Lake trout, although Arctic char, Burbot, Dolly varden, round whitefish, and slimey sculpin were also captured.
Fish were collected on each river/lake. Coordinates and/or specific station locations were noted. All fish captured during the field season are measured, weighed, tagged (if large enough) and released. If fish were not previously tagged, they were tagged with Passive Integrated Transponder (PIT) tags which can be read with a whole stream antenna to track the migration of the fish, predminately Arctic grayling, throughout the systems.

Summary of Methods:
FishCollection:
All fish (adults and juveniles) captured during the field season are measured, weighed, tagged and released. Fish are captured using fyke nets, weirs, or by angling. Fish greater than 30 cm were tagged with Full (FDX) or Half duplex tags (HDX) internal tags. Arctic grayling between 20 and 30 cm in total length were tagged with external floy tags (indicated by a color and a number). This information when added to a long-term tagging file (1985 to present) and will yield information on grayling movements".
