Fish Salvage Activities Related to Diamond Mine Construction in the NWT
Diavik Diamond Mines Inc. (DDMI) is currently developing the Diavik Diamond Mine at Lac de Gras, Northwest Territories. Development of the mine involves the extraction of diamonds from four kimberlite pipes located beneath the substrate of Lac de Gras. The mine requires construction of a system of w...

This program offered an excellent opportunity to collect information on fish species, morphology and health in the Lac de Gras area. A variety of capture methods were utilized, including gillnets, trap nets, minnow traps and angling. Captured fish were transported across the dike to a processing area on Lac de Gras, where fish were identified and morphological parameters measured before release. Fraser recovery boxes were utilized for the first time in 2002, resulting in markedly improved survival of cisco (Coregonus artedii) and round whitefish (Prosopium cylindraceum). The study also demonstrates how environmental protection can be achieved successfully with industry working in collaboration with government agencies.
