Résumé:
This licence has been issued for the scientific research application No.5031.
The study is continuing to investigate whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which we have been studying since the early 1990s. The research team plans to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area and also plans ...

The objectives of this project are to:
1) continue to investigate trends in mercury, metals and persistent organic contaminants (POCs) in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in Great Slave Lake in 2017 to further extend the long-term (1993-2015: POCs, 1993-2016 mercury a...

Résumé:
The objectives of this project are to apply short term sublethal exposures to contaminants of concern with locally collected small bodied fish to establish measures of the relative bioavailability and effect in the Slave River. This information will then be applied to the Community Based Monitoring (CBM) program data to assess exceedances in a more comprehensive manner.
Small fish (for exampl...

The objectives of this project are:
1) to determine through which lakes are important as food sources in four Dehcho communities and which fish species are used for human food from these lakes;
2) to train community monitors to collect fish and other samples according to Environment Canada and Department of Fisheries and Oceans protocol;
3) to involve local school children in the studies by ...

Résumé:
The objectives of the field program are to quantify egg deposition by depth on available habitat for fourteen known or suspected representative shallow reefs and for ten representative deep water reefs in Nonacho Lake, also to conduct mercury sampling in Lake Trout from this lake.
At each of the known or suspected lake trout spawning reefs, a total of 10 numbered egg nets will be buried in cobb...

2009 Résumé:
For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...

1995
Résumé:
The researchers will sample the fishes in three areas (below the rapids at Fort Smith, at the mouth of the Salt River, and in the delta) throughout the open-water season to monitor broad patterns of habitat distribution of the different species and different sizes/ ages of each species. Fish will be collected by use of multi-mesh gill nets, set lines and seines. Fish measurements, aging structu...
