Salmon in the Classroom
By: Ben Forbush & Wade Bonnici
They are born in fast moving, freshwater streams and rivers.
What do Hatchlings Feed on?
Hatchlings feed on a huge pouch of egg yolk under their bellies.
As They Develop Where Do They Go? What Do They Eat?
As they leave their gravel nest they feed on anything floating near them, but insects are their favorite. The fish migrate to sea soon after they leave their nest, but young salmon spend about 4-18 months living in streams.
Where Do Adult Salmon Reproduce?
They lay their eggs in nests made out of gravel, and those nests are made in fast moving streams and rivers.

Eggs and newly hatched alevins often are eaten by sculpins and probably other small fishes. Young Chinooks undoubtedly are eaten by larger salmon and lake trout. Large Chinook have very little to fear in the way of predators, except for humans.
What they eat?
While living in the parent stream, young Chinooks consume a variety of terrestrial (land) and aquatic (water) insects and side swimmers. After moving to Lake Superior, they begin to consume a variety of fish, especially smelt and Ciscoes.
