Salmon Adventure!

Our little salmon that we raised from eggs are almost ready to be released.
They started out as eggs about a centimeter big from the Wolf Lake State Fish Hatchery. Our class came along and picked them up. That is where our journey started!

At school, in the science lab, we got a tank for the salmon eggs. Mrs. Miller put the eggs in the tank, after school hours. Gibson witnessed it all. This is what he had to say about it:
"My mom told me that they were in this big bucket. Mrs. Miller filled the tank up with a bunch of water. She then delicately placed them in the tank. I was really excited that they were putting them in, so my mom told me all about it."

The next day we came to school and they were floating around in a little container. They were starting to fall out of the container to the bottom of the tank. There they sat until they hatched. After a few weeks, they started to poke their little heads and tails out of the eggs. The little egg shells floated around in the tank and stuck to the big filter foam.

Over the next few weeks, we saw their yolk sacs start to disappear as they "buttoned up". Then they needed to be fed! The caretakers fed them the first food size. Over the course of the next two weeks, they started getting bigger, their bellies started to shrink, and their yolk sacs completely disappeared!
 We watched as they started to swim around! It was amazing.

Now they are about a few months old, they are about two inches long, about an inch fat, and they are ready to be released on Monday, May 22nd! Please check back because we'll post pictures!
