Objective(s): To identify what fish species are in Ruth Lake and Bullmoose Lake; also, to determine if the fish are bioaccumulating heavy metals.

Project Description: The objective of this study is to identify what fish species are in Ruth Lake and Bullmoose Lake and to conduct tissue sampling which will assist in determining if the fish in these lakes are bioaccumulating heavy metals.

Fish will be sampled using techniques such as minnow trapping, seining, gill netting, angling and possibly boat electrofishing.

Nets and minnow traps may be left at the sampling locations overnight. No on-site testing will be conducted, but representative fish from each lake will be collected. Representative fish from specific age classes, size, and species will be collected.

A final report will be produced and presented to INAC and Public Works. These government agencies will be communicating the results of the study to individuals and communities in the NWT.

The fieldwork for this study will be conducted from October 15, 2010 to December 31, 2010.
