Summary: A deflection board weir was used to assess the size of the upstream run of dolly varden charr at Big Fish River in 1991. Results suggested that migrant non-spawners may have been deterred by the weir. Consequently, the 1992 attempt to estimate run size used tagging methods at the Cache Creek site. The fish tagged at Cache Creek will be captured at the Fish Hole in the fall in order to produce a...

Licensed Year(s): 1993
Summary: The North Water Survey for beluga will involve the use of satellite images to locate open water, and photography to instantly record large numbers of beluga and other marine mammals sighted. Work will be conducted out of Resolute and Pond Inlet, and the survey will take in all areas of open water north of 73'00 latitude. The survey is a result of a recommendation by the 1992 Canada/Greenland Com...

Principal Investigator: Chiperzak, Doug
Licensed Year(s): 1992
Summary: The researchers will conduct a mobile hydroacoustic survey from a 20 ft. boat using a BioSonics dual-beam echo-sounder and recording system. A limited amount of gillnetting will be conducted to provide groundtruthing information for the acoustic data. Target strength analysis will also be conducted....

Principal Investigator: Ash, Gary R.
Licensed Year(s): 1994 1993 1992
Summary: The researchers will obtain baseline water quality data for the study waterbodies, discharge information for the major streams in the study area, baseline information on fish species composition and relative abundance in the study area, and information of background levels of metals in fish tissue from selected waterbodies in the area....

Principal Investigator: Graham, Mark S
Licensed Year(s): 1992
Summary: The researcher and his team will use several species of planktonic and benthic invertebrates from Lancaster Sound region to evaluate the metabolic cost of making a living in the Arctic. Oxygen consumption techniques will be used as a metabolic indicy. Trophic status of specimens will be evaluated later by stable isotope analysis....

Principal Investigator: Tallman, Ross F
Licensed Year(s): 1993 1992
Summary: The researcher and his team will conduct a collaborative project on Broad Whitefish stock abundance, migration timing, fisheries technical training and traditional knowledge. They will monitor the absolute numbers of one of the Whitefish grouping using counting fences, mark-recapture techniques and hydroacoustics....

Principal Investigator: Sandstrom, Stephen J.
Licensed Year(s): 1992
Summary: This project addresses questions pertaining to the energy composition and habitat utilization of female sea-run Dolly Varden char (Salvelinus malma) of the Yukon Slope. The direct consequences of energy partitioning to fucundity (spawning success) and stored energy reserves (overwintering success) have significant effects on population abundance....

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...

Principal Investigator: d'Entremont, Andre
Licensed Year(s): 1991 1990
Summary: A sampling program will be undertaken where sediment and benthic organisms will be collected at six sites sampled in 1985. The samples will be analysed to determine if any statistically significant changes in the sediment chemistry and species diversity and abundance have occurred since the mine began operation in 1985....

Principal Investigator: Sekerak, Aaron D.
Licensed Year(s): 1990
Summary: The Researcher and his assistant will obtain information on fish in the area so that potential impacts of mining in the region can be assessed....
