Further Examination of the Bio- Magnification of Mercury within Fish Species of the Deh Cho and their Varying Levels among Lakes
Principal Investigator: Swanson, Heidi
Licensed Year(s): 2018 2017 2016 2016 2015 2014 2013
Summary: The objectives of this research project are: 1) to determine why fish mercury levels vary among lakes in the Dehcho region; 2) to identify best predictors of fish mercury levels; and, 3) to determine with fish have the lowest levels of mercury and the highest levels of nutrients. The methods for this project include field sampling, laboratory analysis, and data analysis and reporting. The resea...

Environmental Effects Monitoring for Miramar Con Mine Ltd. and Miramar Giant Mine Ltd.
Principal Investigator: Schryer, Richard P
Licensed Year(s): 2004 2003
Summary: Under the new Metal Mining Effluent Regulations (Fisheries Act), an Environmental Effects Monitoring (EEM) program is required to determine the effects of mine effluent on fish and fish habitat. As part of the study, water quality and aquatic organism he...

Metabolism of arctic fish and invertebrates
Principal Investigator: Gerrits, Martin
Licensed Year(s): 1994
Summary: The researchers are interested in understanding how prolonged cold conditions and reduced food availability in winter affect char. Sea-run char must increase their fat levels so that they have enough energy stored for overwintering and reproduction. Research activities will also include collecting fish and invertebrate specimens to make comparisons about cold tolerance and diet of these specimen...

Studies on genetic diversity in freshwater invertebrates and lake trout, at a high arctic site.
Principal Investigator: Hebert, Paul D.N.
Licensed Year(s): 1987
Summary: To continue work on the genetics and ecology of arctic freshwater organisms during 1987. To assess the levels of genetic diversity in ostracode populations, distributional patterns of the dominant ostracodes, while supplementary studies will examine the ecology of ostracode crustaceans and turbellarian flatworms. In addition small samples (5-10 individuals)of Salvelinus namaycush will be obtaine...
