Summary: This licence has been issued for the scientific research application No.4818. This research will investigate whether contaminant levels are changing in fish in Great Slave Lake which the team have been studying since the early 1990s. The research team plan to work with commercial fishery and community collected lake trout from the Hay River and Lutsel K’e areas, burbot from the Lutsel K’e and F...

Summary: The short-term goals are to determine if 2019 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association; and, 3) as well as to look for link...

Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to 1) establish a long-term community monitoring program for contaminants in fish; and 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently coll...

Summary: This study is designed to find out whether contaminant levels are changing in fish (lake trout and cisco) in Great Bear Lake. The research team require fall-caught fish for this study. Twenty whole lake trout and 20 whole cisco of a range of sizes are required from Great Bear Lake. The fish will be frozen immediately after capture and shipped to Environment and Climate Change Canada (ECCC)-Sask...

Summary: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...

Summary: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...

Summary: The purpose of the study is to continue investigating whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the research team has been studying since the early 1990s. The plan is to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area). The research team also plans to collect burbot from the Lutsel K’e and Fort R...

Summary: The purpose of the study is to have Aboriginal participation in monitoring programs at the Diavik site; to assess the quality of fish for eating – records of fish taste, smell and texture from fish caught in Lac de Gras; collection of fish tissue samples to analyze for metals concentrations; collection of fish otoliths to determine age of fish; focus on sampling fish of similar size/age in order t...

Licensed Year(s): 2012 2010 2009
Summary: This licence is being issued for the scientific research application no.1050. The objectives of this research are to: 1. collect 15 lake trout, 15 whitefish and 15 herring for analysis of metals, including mercury, radionuclides and organochlorine pesticides; 2. compare the levels of the compounds with the same species near the mines in the eastern part of Great Bear Lake. Fish will be colle...
