Project Description: The objectives of this research are: 1) to gather baseline data on size, age structure, fecundity (egg number per female), growth and mortality for lake trout in the study area; 2) to determine if lake trout are genetically distinct between basins of Great Bear Lake; and, 3) to determine the extent of movements by lake trout in Great Bear Lake by using molecular genetics. Field crews will be transported to field sites via float plane. For stock assessment purposes, experimental gill nets with varying mesh sizes (1.5-inch to 5.5- inches) in combination with commercial size gillnets (5.5 inch) will be used to capture a representative sample of lake trout and by catch species of varying sizes. Live by catch species and trophy size lake trout will be measured for length clipped for aging and released. Captured fish will be sampled for the following biological characteristics: fork length, round weight, gonad weight, sex, an... Show more
