Objective(s): The objectives of this study are to: 1) gather baseline data on size and age structure, fecundity (egg number per female), growth and mortality of Dease, Smith, McVicar, McTavish, Keith arm lake trout. A different arm will be sampled each year over a 5 year time period. 2) To determine if lake trout are genetically distinct between basins. 3) To determine the extent of movements (if any) by lake trout in Great Bear Lake by using molecular genetics.

Methods: fish will be caught using angling or 5.5” and multi-mesh standard gang gillnets set in Smith Arm. Location data such as position (determined by GPS), time of year, time of day, net depth, water temperature, weather and other environmental conditions will be recorded for each set. To determine the catch-per-unit effort the net type, set time, lift time and soak time will be recorded. The fork length, round weight, gonad weight, egg number per female, sex and maturit...
