Mortality influences on maturation scheduling in lake trout and lake whitefish and effects on Great Lakes fisheries management

In the project, we will develop models of size selective due to sea   lamprey predation, gillnet harvest and trapnet harvast for the two   species. We will intergrate these models into a life history model to   predict optimal maturation scheduling. We will also develop a   statistical model to describe maturation schedules of lake whitefish   and simulate how the mortality-induced adaptive changes in life   history traits influence fish population dynamics using a eco-genetic   model. Finally, we will assess the sensitivity of stock assessment   models to inclusion of adpative change in optimal maturation   scheduling.
