|Arctic Grayling Growth on the Oksrukuyik Creek near Toolik Field Station, Alaska 1990-2001||
Arctic Grayling were collected at designated stations on the Oksrukuyik from 1990 to current time. Phosphorus addition has occurred from 1991 to 1996; station sites are relative distance from the original 1991 dripper. Grayling were caught, pit tagged, weighed, measured, and then released back into the river.
|Arctic Grayling Growth in the Kuparuk River; data from 1986-2003||
Adult Arctic Grayling were caught and tagged in the Kuparuk River. A second fishing campaign occurred later in the summer, and any fish that was recaptured was remeasured to determine growth. Phosphorus addition has occurred since 1983; station sites are relative distance from the original 1983 phosphorus dripper. Stations include sites in a reference, recovery, and fertilized reach. Reaches were defined based on the location of phosphorous addition (see methods). Arctic Grayling were... more
|Arctic Grayling length, weight and tag data from Arctic LTER Streams project, Toolik Filed Station Alaska, 1985 to 2018||
Since 1983, the Streams Project at the Toolik Field Station has monitored physical, chemical, and biological parameters in a 5-km, fourth-order reach of the Kuparuk River near its intersection with the Dalton Highway and the Trans-Alaska Pipeline. In 1989, similar studies were begun on a 3.5-km, third-order reach of a second stream, Oksrukuyik Creek. Fish were collected on each river. Station locations, representing kilomter values certain distances from original phosphorus dripper (see... more
