Biological Studies of Waters Along the Proposed Mackenzie Gas Project Pipeline Route - Deh Cho and South Slave Settlement Regions
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2008
Résumé: This licence is issued for the scientific research application #861. This study is designed to examine streams possibly affected by the proposed Mackenzie Gas Project pipeline and streams that can serve as future control/reference sites. The researcher will measure the following: nutrients and metals in stream water, stream water quality (DO, pH, conductivity, etc.), and aquatic invertebrate ab...


Investigation of factors affecting high mercury levels in fish in lakes in the Mackenzie River Basin (2002-2003)
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2003 1998
Résumé: This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...


Environmental Studies of the Aquatic Resources of Spyder Lake.
chercheur principal: Reed, Shawna
Année(s) de permis: 1994
Résumé: The researcher will determine fish presence/absence and/or densities (number of fish per unit stream length) by electrofishing representative habitat (eg. pool, riffle, run) and the setting of baited minnow traps. When these two methods are not practical (eg. depth too great or flow too fast), gillnets and/or beach seines will be used. Fish caught will be identified, measured, weighed, sexed and t...


Environmental Studies of the Aquatic Resources in the Lac de Gras Area.
chercheur principal: Pelletier, Clem
Année(s) de permis: 1994
Résumé: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...


Environmental study of the aquatic resources of the Thonokeid Lake area
chercheur principal: Couture, Richard
Année(s) de permis: 1994 1994 1993
Résumé: The researchers of Rescan have been contracted by B.H.P. Minerals Canada Ltd. to conduct an assessment of the types of fish and other aquatic organisms that are found in the Thonokeid Lake area. Tissue samples will be collected in order to assess heavy metal contaminants in fish. An environmental report will be submitted to the Territorial Government on the results of this study....
