Objective(s): To obtain current information about the health of some subsistence predatory fish in ten commonly used lakes by residents of the Sahtu Settlement Area.
Project Description: This study will provide current information about the health of some subsistence predatory fish in ten commonly used lakes by residents of the Sahtu Settlement Area (SSA). This investigation may help to identify alternative sources of fish from lakes not impacted to the degree as seen in Kelly Lake. A future, far more thorough study of mercury abundance and bio-magnification trends may also result from this investigation. Three teams of two people each will collect fish with gill nets of varying size from six lakes. The teams will consist of local people from three communities including Norman Wells, Tulita and Deline. The Norman Wells team will set nets in Hodgson (Jackfish) Lake, Lennie Lake and Kelly Lake; Tulita will sample Stewart Lake and Tate Lake; Deline will harvest Lac Ste. Each lake sample will consist of a minimum of 20 fish representing three age/length classes that will help determine bioaccumulation rates... Show more
