• Antropogenic Stressors and Diagnosis of their Effects on Lake Trout Populations in Ontario Lakes
  
  

  1991. Evans, D. O., J. Brisbane, J. M. Casselman, K. E. Coleman, C. A. Lewis, P. G. Sly, D. L. Wales and C. C. Willox. Ontario Ministry of Natural Resources.

  Summary: This report documents the status of lake trout stocks in Ontario and reviews the effects and extent of the influences of : exploitation, introduced species and stocks, habitat and watershed manipulations, domestic and industrial effluents, and long range transport of atmospheric pollutants on lake trout populations.. An approach for field assessment, diagnosis, and attribution of stress effects for these populations is also proposed.

• Environmental and Genetic Factors Affecting the Physiology and Ecology of Lake Trout
  

  
  

  1990. MacLean, N. G., J. M. Gunn, F. J. Hicks, P. E. Ihssen, M. Malhiot, T. Mosindy and W. Wilson. Ontario Ministry of Natural Resources.
  Summary: This report examines the genetics, feeding behaviour and diet, habitat and spawning behaviour of lake trout and discusses the role of these factors in the management of lake trout.

• Fish Community and Environment Effects on Lake Trout
  
  

  1990. Carl, L., M.-F. Bernier, L. Deacon, P. Hulsman, D. Loftus, D. Maraldo, T. Marshall and P. Ryan. Ontario Ministry of Natural Resources.
  Summary: This report examines aspects of the relationship of the aquatic community to lake trout biology and yield.  We review the fish community type concept, its relevance to managers and alternative schemes for grouping lakes for management purposes.

• Sampling Ontario Lake Trout Stocks: Issues and Standards
  

  
  1991. Lester, N. P., M. M. Petzold, W. I. Dunlop, B. P. Monroe, S. D. Orsatti, T. Schaner, and D. R. Wood. Ontario Ministry of Natural Resources.
  Summary:  A cost-effective approach for evaluating the status of lake trout in Ontario lakes is developed. This report describes two types of lake trout assessment programs: one for Fisheries Assessment Unit lakes and the other for district lakes.

• Inland Ontario Lakes Designated for Lake Trout Management
  
  

  2006.  Ontario Ministry of Natural Resources.
  Summary:  This report lists the 2283 inland Ontario lakes (exclusive of the Great Lakes) that are currently designated for lake trout management.  The list includes 2098 lakes that are managed for naturally reproducing populations (‘Natural’ lakes) and 185 lakes that are managed for put-grow-take stocking (‘P-G-T’ lakes).  ‘Natural’ lakes include those lakes that may have lost populations but have been identified for rehabilitation.  ‘P-G-T’ lakes are managed to provide recreational fishing opportunities and/or to direct angling effort away from more sensitive ‘Natural’ lakes.

• Effects of Hypoxia on Scope-for-Activity of Lake Trout: Defining a New Dissolved Oxygen Criterion for Protection of Lake Trout Habitat
  
  

  2006. Evans, D. O.  Ontario Ministry of Natural Resources.
  Summary:  This report defines a dissolved oxygen criterion for the protection and sustainability of lake trout populations in Ontario lakes and identifies an appropriate and practical way to implement the criterion. Technical Report 2005-01, Revised April 2006.
