Goodbye Salmon!

We had a very successful hatching and raising experience this year as a large percentage of our 1,000 eggs survived to the fry stage. As many of you know the recent flooding threw a curveball into our Willamette River release day plans and ultimately we had to cancel the classroom trip. While it was disappointing to all, our students were good sports as we explained that sometimes nature presents situations out of our control and we have to roll with it. Since we did not have access to any safe site on the Willamette, our biologist at Oregon Department of Fish and Wildlife gave us permission to release our fish in nearby Chehalem Creek. Thanks to the Garstkas for allowing us to park in your driveway and providing safe access to the creek for release. While it was unceremonious in pouring rain today, Mrs. Reed, Mr. Milner, and Mr. Evers made sure the salmon made it safely in their new home. Who knows, maybe in four years a few salmon will make their way back up the Chehalem!


Fry Time!

Our little red eggs have now grown to the fry stage, and they are eagerly anticipating release day next week. They are also quite grateful that release day was not this week during all the extreme flooding.

Almost Fry!

Our salmon are entering the fry stage and are practicing their swimming skills. They are getting their fins in shape for release in the Willamette River in the next few weeks. Take a look at their progress in this video clip! 

Growing Alevins

Our alevin friends have grown a bit since the last video clip. All along, we have been learning about salmon survival rates, external features, and life cycles. Students have started research about salmon species will be writing reports after Thanksgiving break. In December we have some exciting plans regarding learning about stream surveys and stream engineering as well as releasing our finned friends.

What’s the foam at the top of the tank?


Relax… fortunately it is not soap bubbles. When salmon or trout eggs hatch, some of the contents of the eggs create a hatching foam at the top of the tank. It’s not harmful and can be scooped out.

Alevins Everywhere!

All of our eggs have hatched in both of our incubators. Our students have noticed that the alevins behave differently between both incubators as one has more gravel spread out than the other.  

Our Salmon are Hatching!

Some salmon eggs in both of our classroom incubators are beginning to hatch. Take a look at a few of our new alevins!

Visiting Salmon Eggs with the GoPro

Here is a clip showing our salmon eggs. They’re in the eyed stage. Still waiting for them to hatch!

Salmon Eggs Have Arrived!!

Our chinook salmon eggs have arrived. Now it’s time to let them hatch and group up and develop in our incubators. Along the way our students will learn about them and engage in many great activities. More to come….

Chinook Salmon Release

It was a little sad to seem them go, and they were a real good group of fish, but it was time to move on with their lives. Yesterday we released our 1,000 chinook salmon fry that we raised in our classrooms since October 23rd. The we]ather was great, for December, and certainly better than the below freezing temps we had last week. The water temperature was 37 degrees so it was chillier than the 52 degree water our chinook fry were used to, but they seemed to adjust fine. Below is a short video of our release day beginning with our students scooping them out of the incubator. Our next planned hatch will be rainbow trout in the winter of 2015!
