The salmon eggs have arrived! Mrs. Bragan’s class has adopted fifty coho eggs. Trudy, from the Quatse Salmon Stewardship Centre, brought the eggs to Alert Bay School on January 12.
The class had the aquarium ready for the eggs. The students have been learning about what salmon need to survive in the aquarium and in the wild. The students took turns placing the eggs into the aquarium.
Mrs. Hauser captured this interesting video of the salmon moving inside the egg.
We welcomed the arrival of our salmon eggs with a traditional salmon dance song. Students are learning to drum along to the song in Culture and Language class with Ernest Alfred.
The photo below shows us the eyed egg stage. We can see the salmon’s eye and early nervous system through the egg shell.
When the salmon break free of the soft shell their yolk sack hangs below their bodies. At this stage they are called Alevin. The nutrient-rich yolk sack feeds the alevin for about a month while the alevin grow bigger.
Mrs. Bragan’s students record their observations of the salmon.
Alevin like to hide under and behind rocks.
In early March the salmon finished their alevin stage and became fry. They started to swim all around the aquarium. Each day a student from Mrs. Bragan’s class fed the fry with fish food.
