Summary: The purpose of this study is to collect information about a variety ecosystems crossed by or in close proximity to the potential routes for a proposed pipeline. Fisheries and water quality studies will involve a survey of fish habitat, and of the water quality of any water bodies allong the proposed routes. Any fish collection will be outlined by Department of Fisheries and Oceans research permits...

Summary: This study is to identify existing habitat characteristics of the potential and existing stream and pond crossings of the Highway #3 reconstruction project. Field studies will involve the identification of fish habitat characteristics, the potential identification of present fish species in those systems that suggest fish habitat is present by using seine netting techniques. Background data search...

Summary: This study serves to identify existing habitat characteristics of the identified portion of Baker Creek, identify resident fish communities at the time of sampling, and to identify potential rehabilitation and restoration concepts to assist in the re-establishment of historic fish habitat conditions. Field studies will involve the identification of fish habitat characteristics, the identification ...

Principal Investigator: Bryant, Wayne
Licensed Year(s): 1998
Summary: The Gazelle environmental baseline study will include specific investigations on water/sediment quality, lake bathymetry, limnology, catchment hydrology, fisheries and fish habitat assessment. Field data collection and observations will take about two to three days. Field staff of 3 will be transported by air to Ekati from Yellowknife. From Ekati, helicopter transport will be used to drop off the...

Principal Investigator: Digel, Mark
Licensed Year(s): 1998 1997
Summary: Fisheries investigations, including habitat identification and possibly gill netting, will be conducted in the four small lakes located within the watershed of the orebody of the Thor Lake site. In lakes with fish, will collect 10 fish (up to two species) for chemical analysis. Fisheries investigations, including habitat mapping, gill netting (to verify fish community), will be undertaken in the...

Summary: Transportation to Bluefish Hydro Electric Plant is by boat from the Miramar Con Mine Dock at Prosperous Lake. Two one day field trips to the Plant are scheduled during the collection period. Equipment to be utilized include gill or seine nets, Gee traps, backpack electrofishing unit, water flow meter, water sample bottles, canoe and outboard motor. Sample species include whitefish, lake trout, ...

Principal Investigator: Morantz, David
Licensed Year(s): 1996
Summary: The techniques to be used for the assessment of the fisheries in the Lac de Gras area will include small-mesh (1.5 inch) gillnetting, trapnetting (mark-recapture program), minnow-trapping and electroshocking (backpack model for stream surveys). Most fish will be live-released. A select number of fish will be retained (killed), for aging verification (using otoliths), tissue metals concentration ...

Principal Investigator: Chiperzak, Doug
Licensed Year(s): 1996
Summary: A sample of potential spawners (inconnu) will be tagged (30 radio tags and up to 300 anchor tags) in the area of shingle point, Coney Lake and possible other areas in the outer delta. fish will be captured using a combination of gillnets, box traps, angling, and seining. Tracking of radio tagged inconnu will be done from a fixed wing aircraft. Recapture information from tagged fish captured in ...

Licensed Year(s): 1996
Summary: Study will examine the location and extent of suitable overwintering habitat for charr in Rat River. Another objective is to document the location of spring upwellings at the overwintering site on Fish Creek. Knowledge of winter flow and temperature regimes of the spring and the effect of air temperature on the availability of overwintering habitat will provide managers with some ability to pred...

Principal Investigator: Reed, Shawna
Licensed Year(s): 1995
Summary: The researchers will be utilizing the following techniques for assessing aquatic biota and fish habitat utilization: gillnetting (various sizes and meshes), trapnetting (mark-recapture program), minnow-trapping and electroshocking (backpack model). A select number of fish will also be retained for aging (using otoliths), tissue metals concentration and diet analysis....
