What Do Adult Salmon Feed ON??
Adult Salmon that only live in freshwater have a diet the consists of plankton, insects and baitfish.
Where are Salmon Born?
Salmon are born at the bottom of freshwater rivers in a little divot called a depression. Even ocean salmon are born in freshwater, that is why it is so hard for the salmon to lay eggs. They have to fight the currents and sometimes hop over waterfalls.

Hatch-lings feed do not need to be fed in their early months. They are born with an nutrition sack on their belly which provides food for about a month and a half.
Salmon in the Great Lakes
How did salmon get to the Great Lakes
Salmon is in the great lakes because of us. We brought the to the Great Lakes for 2 main reasons, the amount of fish in the lakes were fading and the amount of dead alewives on beaches were causing less and less tourists visiting the beaches. By migrating salmon to the Great Lakes the alewives were eaten and the beaches were clear and the lakes had more fish.
How have salmon adapted to freshwater??
Salmon is able to do that because of man-environmental changes and over fishing.
Salmon and their food chain
Salmon are at the top of their food chain in freshwater areas when the are adults. They are important to the environment because they at alewives so they are not dead on beaches. This brings tourists to the beaches and gives revenue to the state. Salmon also refills the amount of fish to the Great Lakes.
Nothing in the Great Lakes feeds on Salmon. Salmon eat alewives, insects and baitfish.
Salmon in the Classroom
I think that next tri, you could have different jobs students have to do to help the salmon out. For example feeding, changing out the water, ect. You could also rotate out the jobs that way everyone would get a job and get to do different tasks. You could also have kids go on the announcements telling the school how many salmon are left and which stages they are in. Hope I could give you some good ideas! :)
