Summary: The objective of the project is to study the health of the fish in the Slave River and at the Slave River Delta. A number of different fish species will be collected to study metals, organic contaminants, gene expression and histology. The study focuses on the potential stresses that fish in the region are exposed to, by analyzing gene expression (Ribonucleic acid – RNA), metals, and organic co...

Summary: 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...

Summary: 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...

Principal Investigator: Schryer, Rick P.
Licensed Year(s): 2006
Summary: Sampling of water, sediment, benthic invertebrates, fish inventories, and fish habitat mapping will be done. Water will be collected for chemical analysis, and limnology measurements taken. Sediment will be collected for chemical analysis and particle size analysis. Benthic invertebrates will be collected for taxonomic identification. Fish species, presence and relative abundance will be determine...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1995 1994
Summary: The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....

Principal Investigator: Bong, Tom D.
Licensed Year(s): 1994
Summary: The researcher will collect fish for analyses of contaminant body burdens. The sample size for each species will be 10-15 of each sex at each sampling site. Fish will be collected using set lines set in the evening and fished overnight. Blood samples will be taken from live fish and then tissues will be sampled and sent to labs for analyses. Gut contents will be examined and the fish will be aged....

Principal Investigator: McNaughton, Duane
Licensed Year(s): 1992
Summary: The researcher will drill and complete some 20 observation wells in the vicinity of the Fort Resolution sewage infiltration pit. Sample groundwater and analyze it for sewage derived contaminants and coliform bacteria. A report will be prepared with recommendations based on the findings and submitted to relevant agencies in the N.W.T....

Principal Investigator: Bohn, Arne
Licensed Year(s): 1980
Summary: To conduct an assessment of the impacts of new mining and water discharge. The studies will include: - updating information on soil types and vegetation. - updating information on wildlife habitat. - updating information on water quality and fish habitat. - examining background levels of trace metals associated with Pine Point Mining activity....
