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 main objective of the study is to implement a one-year environmental monitoring program to support a 2019 water licence application as well as associated regulatory requirements. Three studies will be done in 2019: a) Phase 6 Environmental Effects Monitoring (EEM) program; b) Fish tissue; and, c) Fish presence/absence, habitat survey and benthos sampling. The Ninespine Stickleback su...

Summary: The purpose of this project is to obtain baseline data for fish communities in Gwich’in Settlement Area (GSA) and Inuvialuit Settlement Region (ISR) lakes and use these data to predict future changes in fish communities caused by climate change. Specific objectives are: 1) to develop a baseline data set for fish populations, fish habitat, water quality, and water temperature for small and m...

Summary: This research is intended to meet regulatory requirements from the Snap Lake Environmental Assessment and under the mine's Water License, Land Use permit and Environmental Agreement. The objectives of this research project are to obtain and determine annual variability of the relative abundance, distribution, group composition and behaviour of caribou; the relative activity of grizzly bears; t...

Summary: The multiyear monitoring programs at Bluefish accomplish the following objectives: • Monitoring effects to fish habitat from changes in water level and flow through Reach 1; • Monitoring of the seasonal use of Reach 1 and the Tailrace Area by spawning fish; • Monitoring of mercury concentration in large-bodied and small-bodied fish; • Continue winter investigations of egg incubation conditions...

Summary: This study is continuing to 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 will collect lake trout from the Hay River and Lutsel K’e areas. The team will 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 ...

Summary: The objective of the study is to carry out the third year of periodic monitoring of fish and benthos at the determined study locations; Jackfish Bay (exposure area), Horseshoe Island Bay (reference area for fish survey) and Kam Bay (reference area for the benthos survey), to determine if treated Con Mine effluent is affecting fish and fish habitat. The study has been designed to replicate the stud...

Summary: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...

Summary: Objectives of this research are to: 1. establish a population estimate of walleye in Sanguez Lake; 2. establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3. reduce the number of walleye and pike adults such that predation on walleye recruits decreases...
