Salmon Incubation
The fertilized salmon eggs we collected at Crooked Creek were brought back to the classroom where we placed them in a chilled aquarium. We checked the water to make sure the temperature stayed around 5 degrees celsius. Before long we noticed the eggs had two little dots which meant they had developed their eyes. (eyed-eggs) During Christmas break the salmon eggs hatched and the alevin were at the bottom of the tank hiding in the gravel. The Alevin’s egg sac was slowly absorbed and the fry swam upward in the tank and were ready to feed. We fed the fry around three times a day. We had to keep the tank clean by changing out the water and using an aquarium vacuum. We released the Chum salmon fry into Crooked Creek the first part of May.
