Adult Lake Trout and Chinook salmon live in deep, open water and eat small prey fish, but they have very different reproductive strategies. Lake Trout live up to 10 years and spawn (breed) every year near the lake shore. Most Lake Trout that live to adulthood eventually die in the open water and their carcass settles to the lake bottom. Salmon live 3-4 years and only spawn once. When they spawn, they swim up river in the Fall (sometimes all the way to MSU, via the Red Cedar River), where they build nests in gravelly river beds, lay their eggs in the nests and the males fertilize the eggs. Then, both the males and the females die. Q3. In 1-2 sentences, explain how the life history trade-offs of Chinook salmon and Lake Trout are different. How do such different strategies still increase fitness of the individuals?
