Objective(s): To investigate whether contaminant levels are changing in fish in Great Slave Lake.

Project Description: This study is continuing to investigate whether contaminant levels are changing in fish in Great Slave Lake which the research team have been studying since the early 1990s. The team plan to collect lake trout from the Hay River and Lutsel K’e areas. The team also plan to collect burbot from the Lutsel K’e and Fort Resolution areas of Great Slave Lake, and northern pike from the Fort Resolution area of Great Slave Lake.

Twenty burbot and 20 northern pike will be collected from the West Basin of Great Slave Lake (near Slave River) by community members from Fort Resolution during their normal subsistence fishing activities (gill net or angling). Twenty lake trout will be collected from the West Basin of Great Slave Lake by the Hay River commercial fishery (gill net). Twenty lake trout and 20 burbot will be collected from the East Arm of Great Slave Lake by community members from Lutsel K’e during their normal subsistence fishing activities (gill net or angling).

Community members (chosen by the local Renewable Resource Council’s) will collect fish for this study. Communities will be kept informed of the progress of the study. M. Evans may visit the communities to discuss the study and present results from previous years.

Results will be disseminated through reports and possible community visits.

The fieldwork for this study will be conducted from September 1, to December 31, 2016.
