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...

The biogeography and ecology of deepwater sculpin (Myoxocephalus thompsoni): conservation of a glacial relict
chercheur principal: Sheldon, Tom
Année(s) de permis: 2004
Résumé: The deepwater sculpin is a small species of fish found only in the deepest lakes in Canada. Its closest relative is the marine fourhorn sculpin which is distributed in shallow marine waters of the arctic North American coast. To resolve the issue of orig...
