Alevin & Fry Stage

Dear Division 15,

Today we started to learn about the Fry Stage of the salmon.  Last week we read and wrote about the Alevin Stage.  Isn’t it amazing that they Alevin have a yolk sac and the Fry have a swim bladder? I wonder why the Alevin need a yolk sac and why Fry need a swim bladder?

What do you find interesting about these two different stages of the salmon?  What are some facts that you know about the Alevin or Fry stage?  If you have a question please share.

From, Ms Sim
