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!
