Proceedings of the regional advisory process on the stock status of Lake Whitefish (Coregonus clupeaformis) in Great Slave Lake; January 26-27, 2011
Chairperson: Dr. Ross Tallman
Editor: Chris Day
A Fisheries and Oceans Canada (DFO) regional science advisory meeting took place on January 26-27, 2011, in Winnipeg, MB, to assess Lake Whitefish (Coregonus clupeaformis) stock status in Great Slave Lake (GSL), Northwest Territories. This meeting was held in response to a request from DFO Fisheries and Aquaculture Management (FAM) sector for science advice on the current status and sustainable harvest level for the GLS commercial Lake Whitefish fishery. These whitefish stocks were last assessed in 1992 although between 1972 and 2002 numerous data reports have been published by DFO. Since 1972, DFO has conducted a series of biological observations, including the collection of age structures from fish plants and a study of the effects of reducing the minimum gillnet mesh size. Plant sampling was done for each of the six commercial management areas of the lake. From 1972 to the present, this study represents a comprehensive analysis of all plant sampling data collected from the lake.
Meeting participants included DFO Science and FAM Sectors and two professors from the Universities of Waterloo and Manitoba. Science advice resulting from the meeting is published in the DFO Canadian Science Advisory Secretariat (CSAS) Science Advisory Report series and supporting data and analyses are published in the CSAS Research Document series.
