Trophic relationships in Great Bear Lake using the ecopath model [electronic resource] : preliminary analysis / by M.Y. Janjua, R.F. Tallman and K.L. Howland. Winnipeg : Fisheries and Oceans Canada, c2015. v, 24 p. : fig., maps, tables. Canadian technical report of fisheries and aquatic sciences, 1488-5379 ; 3137 Includes bibliographical references (p. 11-16). This is a first attempt to model a sub-Arctic freshwater ecosystem in North America and to better understand the trophic structure and function of the pristine GBL ecosystem. An ecosystem approach to fisheries management in this lake is identified as an important research goal by the Great Bear Lake Working Group (GBLWG 2005, Muir et al. 2012). Trophic network modeling of Great Bear Lake has provided some useful information for the purpose of ecosystem based fisheries management. Despite being preliminary, this model gives a cohesive view to explore questions about the functioning of this pristine ecosystem. It provides a heuristic approach for evaluating interactions of all important components and groups in this simple ecosystem. gccst Aquatic ecosystems gccst Lakes gccst Modelling gccst Environmental management gccst Fisheries management Tallman, Ross Franklin, 1956- Howland, K.
