Fish Populations / Fisheries
North/South Consultants Inc. has extensive experience in population assessment. The company has the capability and equipment to implement a variety of assessment techniques including: index gillnetting surveys; boat and backpack electrofishing surveys; conduit and wire mesh fish fences; hoopnetting and trapnetting programs; seining programs; visual and remote camera assessments; active and passive acoustic and radio telemetry; and visual and coded tagging.
In addition to the projects listed below, fish population work (including assessments of fish movements via mark-recapture and radio telemetry) are large components of many of North/South's monitoring programs, such as those conducted for the City of Winnipeg, the proposed Conawapa, Keeyask/Gull, and Wuskwatim generating stations, and the Limestone Generating Station.
Representative Projects:
Shoal Lake Water Intake Fishery Impact Study
Assessed walleye spawning activity near the water intake and quantified the loss of eggs, larvae, and juveniles by entrainment or impingement.
Arctic Char Population Studies in the N.W.T.
Conducted two studies for the Department of Fisheries and Oceans: 1) Enumerated Arctic char during their upstream migration in the Big Fish River by use of a conduit weir. 2) With the assistance of local Inuit, Arctic char were tagged and biological information was collected at the Maguse River and at sites along the coast of Hudson Bay to assess commercial fishing quotas.
Aishihik Lake Whitefish Monitoring
Designed and conducted an annual monitoring program to assess the response of a lake whitefish population to lake regulation.
Life History of Coregonids in the Mackenzie River Delta Area
Analyzed and summarized published information on feeding, migration, and reproduction of broad whitefish, Arctic cisco, and lake whitefish.
Goose Creek Fish Passage Study
Assessed whether fish passage was being obstructed by culverts.
