The Great Lakes Assessment and Model Evaluation Review team was created to provide a basin wide focus to Ontario Ministry of Natural Resources stock assessment. This Coordinated Activities Project brought together members from the Province to one location to summarize and compare assessment and modeling methods used on whitefish and walleye on all Great Lakes. Field assessment programs used for walleye and whitefish are summarized in tabular form and each is discussed for four Great Lakes (excluding Lake Michigan). The use of some of the resulting field data in two models is also described as part of the projects purpose was to bring OMNR “up to speed” with the Upper Great Lakes Technical Committee of modelers. One model is regularly used as part of the quota setting process for lake whitefish found in Lake Huron and Georgian Bay and the other is used for lake whitefish population estimation and quota setting within Lake Ontario. Mathematical differences among the models is described as well as the results generated from using each model to analyze both Lake Ontario and Lake Huron whitefish populations.
