Principal Investigator: Hoos, Rick (7)
Licence Number: 15090
Organization: EBA Engineering Consultants Ltd.
Licenced Year(s): 2012 2009 2002
Issued: Jun 18, 2012
Project Team: David Morantz (Senior Fisheries Biologist, EBA), Cameron Kulak (Fisheries Bioloigst, EBA)

Objective(s): 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; and, to determine sediment and water quality (nutrients and metals) as well as benthic invertebrate (10 samples per site) abundance and taxonomic composition at the same sites.

Project Description: 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 water quality (nutrients and metals) as well as benthic invertebrate (10 samples per site) abundance and taxonomic composition at the same sites. Statistical methods will be used to determine whether differences between sample sites (exposure and control) are of statistical significance.

Fish collection will be via electrofishing (backpack), minnow trapping, and kick seining. The research team will measure length, weight, and observe general condition. Tissue sampling will occur with not more than 10 fish per site. The research team will also conduct water quality sampling and sediment sampling (Hess sampler and/or "U" sampler) at each location. Crew will stay in Tungsten during field sampling.

Regular consultations with area First Nations have been maintained by NATCL. Copies of all applications materials will be transmitted to the Deh Cho First Nations in Fort Simpson, Acho Dene Koe Band in Fort Liard and the Nahanni Butte Dene Band to initiate community review of the application.

The fieldwork for this study will be conducted from August 1, 2012 to September 15, 2012.
