Salmonids in the Classroom


A Partnership Between TCSOS and the California Department of Fish & Wildlife

The Salmonids in the Classroom (SIC) teacher workshops give teachers the tools they need to hatch salmon or trout in their classrooms and then release the fish into the wild.  The goal of this program is for the students to learn to be stewards of the watersheds in which they live.

This year, we will be offering the required teacher workshops virtually through Zoom.  New teachers to the program must register for one of Session #1 and one of Session #2.  Pick the dates that work best for you. Asynchronous assignments must be completed during the time between the sessions.

Teachers who have already attended training in the past and want to raise salmon or trout in their classroom this year can download a 772 form here.

Salmon Eggs By the Numbers

Chinook Salmon lay an average of 5,400 eggs. Coming in a close second are steelhead with 4,900 eggs, and the other species ranging from 1,000+ to 3,000+ eggs.

Amazing Life

The Lifecycle of a Salmon



The cycle begins in freshwater, when a redd, or a female’s nest of eggs, is fertilized. These eggs remain in the gravel throughout the winter, and the embryos develop. 



In the spring, the eggs hatch, and alevins emerge. These are tiny fish with the yolk sac of the egg attached to their bellies. Alevins stay close to the redd for a few months. 



Fry swim to the surface of the water, fill up their swim bladders with oxygen, and begin to feed.  Chinook fry usually spend less than 5 months in freshwater



Eventually, environmental cues cause fry to begin their migration downstream towards the oceans. At this time, smolting begins, and scales grow as they turn a silvery color.


Adult Salmon

While some salmon remain in coastal water, others migrate northward to feedings grounds. Chinook salmon may spend up to eight years in the ocean.


Spawning Salmon

Upon reaching natal streams, females build nests, or redds. These little depressions in the gravel are made by the female by turning on her side and using her tail to dislodge stones or pebbles. Males fight with other males for spawning rights with a female. The dominant male will court the female and upon spawning, they release eggs and milt simultaneously. The eggs will settle into the gravel, and the female will cover the eggs with loose gravel and move upstream in order to prepare another redd. Eventually, both the males and females die, supplying the river habitat with nutrients and the seeds of the next generation that will someday return to continue the cycle.
