Surviving the River: Larval Lake Sturgeon


Michigan Environmental Education Curriculum
River and Stream Ecosystems

Once a lake sturgeon egg hatches it becomes a small fish called a larva. Larval sturgeon don't have it any easier than the eggs. There are many predators that want to eat the larvae because they are so small.

Larval sturgeon stay among the rocks where they were hatched, feeding off of a yolk-sac. Eventually they begin to drift downstream.

Larval lake sturgeon are very small, only millimeters in length. They can be difficult for humans to see. For other fish, they are easy to spot. Many larval sturgeon are eaten as they drift down river.
