Salmon Eggs are Hatching!

Some of classroom chinook salmon eggs are hatching in all three of our classroom incubators, and we expect the rest to follow very soon into the alevin stage. Our goal is to release our salmon in Hess Creek, where we held our outdoor school, sometime either mid December or the first full week of January. Stay tuned for more “development!”

Salmon Season!

Our salmon eggs arrived yesterday and they are now acclimating to our classroom incubators, which will be their temporary homes for a few months. Each class incubator now contains between 180 and 220 eggs. The eggs are less developed than in past years, so our targeted release date range is the week before winter break at the earliest or the first week of January. Weather permitting, we plan to release our salmon in Hess Creek, the site of our recent outdoor school. Stay tuned for more “developments.”

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.

Active Alevins

Our chinook salmon alevins are starting to become quite busy in their little worlds. Activity is increasing everyday in both incubators. Ammonia levels have been a concern so we have changed out the water several times. Thanks to Mr. Segundo who has hauled in numerous five gallon buckets of water from our well pumphouse on several chilly mornings. You will note a clearing in the rocks. This is where we dumped in the new water from the buckets. It is interesting to see how the salmon alevins react to it. Stay tuned for more developments!

The salmon are coming!

These lonely incubators will be housing some chinook salmon eggs next week for an upcoming STEM unit. This will be the first time since 1993 when we began the program that we have raised salmon. Previously we have raised rainbow trout. We’re looking forward to this new experience!
