Assessing Determinants of Lake Trout Reproductive Success: Comparison of Lake Superior Reef Complexes with Contrasting Survival Rates of Young Lake Trout

A team of researchers will identify habitat characteristics favored  by spawning and juvenile lake trout over two shoals of the Apostle  Islands in Lake Superior through remote sensing technology. This  study will generate new information about how interactions among  substrate size and stability, water movement, and sedimentation  influence the reproductive success of lake trout.  An understanding  of water conditions coupled with high-resolution GIS information  about habitat selection and use will help natural resource managers  direct efforts to manage populations of these commercially-important  native fish.  The researchers will also analyze the diets of fish in  the areas where juvenile lake trout gather to examine how young  trout fare both in competition and as prey.
