Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
chercheur principal: Hoos, Rick
Année(s) de permis: 2012 2009 2002
Résumé: The objectives of this research are: (1) to determine length, weight, and general condition of 100 fish and tissue analysis of not more than 10 fish (Slimy Sculpin- Cottus cognatus) per site at five site locations in the Flat River: two locations upstream of the CanTung mine site, one adjacent to the mine site and at two locations downstream of the mine site; and, (2) to determine sediment and wa...


Cisco diversity in Great Slave Lake
chercheur principal: Drygeese, Jennifer
Année(s) de permis: 2009
Résumé: The objectives of the research are to: 1) Confirm the taxonomy of the Cisco of Great Slave Lake; 2) Characterize age structure and growth of individuals; 3) Determine prey abundance in capture locations; 4) Consult with, and educate local aboriginal and non-aboriginal communities by having them assist in data collection and presenting to communities the results of research. The benefits ...


Molecular and otolith tools to investigate population of origin of Arctic cisco
chercheur principal: Nielsen, Jennifer L.
Année(s) de permis: 2008 2007
Résumé: This study aims to: 1) use genetics and otolith (ear bone) microchemistry to determine if differences exist between collections of Arctic cisco (herring) made from tributaries of the Mackenzie River (Canada) and the Colville River (Alaska) and 2) use differences to identify population-of-origin of fish caught in the Colville River subsistence fishery. Approximately 60 Arctic cisco will be colle...


Assessment of lake trout stocks in Great Bear Lake
chercheur principal: Howland, Kimberly
Année(s) de permis: 2007 2006 2005
Résumé: The objectives of this research are: 1) to gather baseline data on size, age structure, fecundity (egg number per female), growth and mortality for lake trout in the study area; 2) to determine if lake trout are genetically distinct between basins of Great Bear Lake; and, 3) to determine the extent of movements by lake trout in Great Bear Lake by using molecular genetics. Field crews will be tr...


Aquatic Studies along the Mackenzie River and its Tributaries
chercheur principal: Evans, Marlene S.
Année(s) de permis: 2005
Résumé: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...


New ischnacanthid acanthodians from the Lower Devonian of the Mackenzie Mountains, NT, Canada
chercheur principal: Hermus, Chelsea
Année(s) de permis: 2002
Résumé: The main objective of the project is to collect fossils of two specific groups of early fishes (acanthodians and heterostracans) to supplement specimens already collected for research projects at the University of Alberta. The field party plans to journe...


The Evolution and Interrelationships of Lungfish
chercheur principal: Cumbaa, Stephen L
Année(s) de permis: 2010 2008 1997 1995
Résumé: The researchers will collect samples of Devonian-age rocks in which evidence of fossil fish (primarily lungfish) are present and take them back to the museum laboratory for preparation, study and comparison with other samples in the Museum's collection. All work to be done by hand tools in the field (hammers and chisels)....
