At ARPSES, we are proud to have involvement of Abbotsford schools in raising juvenile coho salmon. The "Salmonids in the Classroom" program includes the raising of eggs in controlled aquarium environments within classrooms. Students come to the hatchery to be involved with the harvesting of salmon eggs.

Through our egg take process, students are able to see spawners at the end of their life cycle and participate in the fertilization of coho eggs (the beginning of the life cycle).

Students then raise salmon in their classrooms until they are released as fry into local streams in the spring.

PRECAUTIONS
PRECAUTIONS
Tape a large sign to cover electric outlets for air filters and refrigerator. (see sample below)
Prepare two 2 Litre bottles of ice and store for emergencies.
SET UP REFRIGERATOR
Set your refrigerator at 7 degrees Celsius (We will confirm at delivery what temperature is best for release after spring break)
Insulation on tightly!
Refrigerator sensor in the water!!!!
Filter air is flowing over refrigerator coils in water.
TANK SET UP REMINDERS
Most schools are now on a system using minimum gravel (1/2 cup) which is removed when the fry swim up and begin feeding. Food and feces are visible and easy to vacuum out. This helps keep the tank clean and free of ammonia.
To help the tank look more natural, place the vinyl image underneath the bottom glass.
HOW IT WORKS…
Turn the tank upside down.
Trim the vinyl to fit flat on the bottom underside of the tank.
Spread 1/4 cup of oil (vegetable is fine) on the image then squeegee this onto the glass so the image is visible when looking into the tank.
Wipe off any excess oil, then tape the edges so it doesn’t curl.
Turn the tank right side up and continue setting up.
NOTE: You must use oil to adhere the vinyl. Otherwise condensation between the glass bottom and the vinyl creates a refraction of light and a mirror effect. The image is not visible unless it fits tight to the glass with no air bubbles.

This system works best when the gravel is spread in a thin layer on the bottom of a glass pie plate. The redd is built on the back half of the plate. After the tank is filled with water, add the plate to the bottom of the tank. (see pictures below). Do not use ceramic plates. Do not use bowls which will block the water/oxygen flow over the eggs.

Students learn to calculate ATUs (Accumulated Thermal Units) which tell them how far along a coho salmon is in its development. By tracking the ATUs, students will be able to predict when their eggs will hatch, when it is time to feed the fry and when it is time to release them to the wild.
