Autumn brings shorter days, falling leaves, and spawning salmon!  Our homeschool network went on a field trip to learn about the life cycle of the salmon at the Nimbus Fish Hatchery.

We saw this bird and would like to know what it is.  So far, I have had no luck in identifying it.  Any bird lovers out there who can help?  (Update: My Dad is the winner with “Osprey”)

We were able to watch the process of harvesting and fetilizing salmon eggs:

  1. The salmon in a holding pen were mildly shocked to keep them from thrashing too much
  2. The holding pen is raised and a man separates the males from the females.
  3. All the fish are clubbed and the females main artery is cut to let all the blood out. 
  4. Once all the blood has been removed, the abdomen is split open and all the eggs are removed.  A salmon makes about 5000 eggs!
  5. The eggs are placed in a small tub and the male salmon is “milked” over the eggs.  A little river water is added and swirled around.  All of the eggs are fertilized withing 20 seconds.
  6. This hatchery has a 98% success rate of hatching and releasing salmon.

Feeding the fish.
