Description

Abstract: Brook trout removal activities were conducted on Threemile Creek beginning in late June, and ending in late September 1997. Removal efforts consisted of electrofishing in the brook trout zone and night snorkel spearing in the bull trout intergrade zone (both brook trout and bull trout present). A total of 121 brook trout and one hybrid were removed by electrofishing. Of the 121 brook trout removed, 92 were greater than 90 mm in length. During night snorkel spearing 10 brook trout and 8 hybrids were removed and a total of 54 bull trout were observed. Macroinvertebrate and amphibian surveys were conducted in early September, and temparature was monitored throughout the project area. Experimental trapping was conducted, but no fish were collected during any trapping effort.

Purpose: The primary objective of the project was to remove and suppress non-native fish species (brook trout and bull trout/brook trout hybrids) in upper Threemile Creek through the use of electrofishing, night snorkel spearing, and experimental trapping.
