Licensed Year(s): 1993
Summary: Three crews of two people each will be stationed at the commercial fishing camps to obtain biological and catch effort data from the fisherman. A supervisor will oversee the project in the field and set some experimental nets in the vicinity of the commercial nets at one of the camps. A minimum of 200 whitefish samples will be obtained from the fishermen's catch....

Licensed Year(s): 1993
Summary: Zooplankton will be collected from lakes and ponds located along a transect between Paulatuk and Shingle Point (Yukon). The specimens that are collected will be identified according to species type and genetic analyses will be performed to determine what species are interbreeding to produce hybrid organisms. Knowledge about zooplankton is important as many organisms (such as fish) depend on thes...

Summary: The researcher will be collecting lake trout and/or arctic charr from lakes in the vicinities of Hay River, Inuvik, Paulatuk and Tuktoyaktuk in order to examine the distributions of these species. Samples of liver and muscle tissue will be collected from these fish for genetic analyses: this research will provide information about how different populations are related to each other (i.e., their o...

Licensed Year(s): 1993 1992
Summary: The researchers will tag broad whitefish in the Mackenzie River Delta in the vicinity of Horseshoe Bend. During this season, fish are moving to areas further upstream. Tagging will provide information about the movements, growth, survival and numbers of whitefish and will contribute to their management. Local residents will take part in a training program on the methods of tagging fish....

Principal Investigator: Romano, Tracy
Licensed Year(s): 1993
Summary: This research will examine the nervous (i.e., brain) and immune systems of beluga by collecting these tissues from harvested animals for laboratory analyses. This study will help to determine how contaminants affect the health of belugas. In addition, the data collected may lead to a better understanding of why whales strand themselves on the shoreline as it has been suggested that beached whale...

Principal Investigator: Aiken, Susan
Licensed Year(s): 1993 1992 1991
Summary: The researcher will continue her study on NWT grasses. She will collect living plants in order to conduct chemical analyses on the plant tissue. These tests will help to identify different species of grasses (especially those that look very similar) and also help to determine where these species originated from. In addition, the researcher has small experiments on grass being conducted by staff...

Principal Investigator: Krebs, Charles
Licensed Year(s): 1993 1992 1991
Summary: The researchers will examine the cycles in lemming abundance (i.e., increases and decreases in the lemming population) for the western arctic region. Ongoing research suggests that lemmings in the Pearce Point area do not appear to reach very high numbers as has been noted in the eastern arctic and Scandinavia. Licence issued for use of Inuvik Research Centre....

Principal Investigator: Clarkson, Peter
Licensed Year(s): 1993
Summary: The researcher will conduct surveys to determine bear population estimates as well as sex and age distributions for the grizzly bear population in the Brock and Hornaday Rivers area. Licence issued for use of Inuvik Research Centre....

Principal Investigator: Smith, David L.
Licensed Year(s): 1993
Summary: This study will address the impact that muskoxen are having on sedge meadows (the habitat that is important for their survival in the Thomsen River valley). In this study, I will examine the response of sedge meadow plants to the effects of grazing by muskoxen. I will monitoring the growth and chemical makeup of plants in 3 situations: (1) unprotected plots subject to muskoxen grazing; (2) artif...

Principal Investigator: Stabler, Matt
Licensed Year(s): 1993
Summary: Anadromous arctic charr, currently viewed of as the eastern form, are known to spawn and overwinter in the DeSalis River system. Residents of Sachs Harbour have expressed an interest in harvesting arctic charr from this system for consumption and commercial purposes. Two resident monitors will sample the subsistence catch of this stock in order to estimate stock size and age. Whole fish will be ...
