Classroom Aquarium Education Program (CAEP), regionally known as Salmonids in the Classroom, is a project-based science program for grades pre-K to college. CAEP offers students and classroom teachers a hands-on opportunity to learn about the life cycles and habitat needs of these amazing fish. By understanding the need to conserve habitats, students become stewards of local watersheds and can make informed decisions in the future.

Students in CDFW’s Central Region (4) hatch rainbow trout or chinook salmon eggs and raise them to young fry, before releasing them in local approved waters. In some parts of the region, local community organizations partner with schools to help make the program happen.

Frequently Asked Questions

I am a new teacher - how do I get started?

  • New teachers should sign up for a new teacher training before applying for eggs. These trainings 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. Visit the links above to sign up for a new teacher training.
  • Workshops are offered annually in the fall. If workshop dates have already passed for the current school year, keep an eye on our web page for next year’s training dates.

I am a returning teacher - what do I need to do this year?

  • Returning teachers who have participated within the last 3 years should apply for eggs once the online application is live. Active teachers are not required to retake the teacher training, but are welcome to participate to refresh their knowledge.
  • If it has been more than 3 years since you last participated in the program, you will need to be recertified before applying for eggs. Please sign up for a new teacher training before filling out this year’s application for eggs. Visit the links above to sign up for a new teacher training.

I'm certified in a different region. Do I need to take the training again in Region 4?

Yes! Since the Classroom Aquarium Education Program varies between regions, it is highly recommended that teachers entering Region 4’s program participate in a Region 4 teacher training. Please reach out to Gail.Davis@wildlife.ca.gov if you would like to discuss your situation.

I've worked with another teacher who did the program. Do I need to take the training to have my own aquarium?

Yes! All teachers must be individually certified in order to receive an aquarium and eggs. Certifications are not transferrable. Please sign up for a new teacher training in order to participate this year.

Will I get salmon or trout eggs?

The type of eggs received will vary by area. You will learn which species is available for your area during your teacher training.

What costs are associated with this program?

Teachers should plan to purchase their own equipment (aquarium, filters, chillers, etc.) which can cost up to $500 or more depending on the type you purchase. A detailed list of the equipment needed for this program will be provided during the teacher training.

Often, teachers are able to offset these costs with mini-grants, parent clubs, or other funding sources available through your district. Reach out to your school’s administration for funding support to help cover the cost of equipment.

There may be equipment available to be lent out to teachers. Please contact Gail.Davis@wildlife.ca.gov to inquire about borrowing equipment after you have completed the training.

What is the timeline for this program?

  • Teacher trainings are offered in the fall. Applications for eggs are due by December 1st of each year.
  • Teachers should expect to have eggs in their classrooms for 6-8 weeks before release.
  • Salmon eggs arrive in January and are typically released in March
  • Trout eggs arrive in February and are typically released in April
  • Exact dates will vary each year based on spawning season, egg availability, and environmental conditions. Your coordinator will communicate the egg delivery date as soon as this information becomes available from the hatchery.
  • Teachers will need to set up their aquarium at least 2 weeks before receiving eggs, in order to set the temperature and work out any issues before egg delivery date. For salmon, it is good practice to set up your tank before leaving on winter break. For trout, it is good practice to set up your tank in mid-January.
  • Teachers are required to submit a release summary form within 2 weeks of releasing fry. If your eggs/fish die before release, teachers must submit the release summary form within 2 weeks of the last fish dying.

Approved Waterbodies

Upon receiving eggs, teachers will receive an authorization form with an assigned, approved waterbody for release. Fry must be released into the waterbody that is listed on your authorization form. See guidelines for more details. 

Waterbodies are approved for CAEP releases by CDFW scientists. Approvals are reviewed annually, and the list of approved sites is subject to change based on environmental conditions. A list of the waterbodies approved for the 2025-26 school year will be provided to teachers when this year's CAEP application opens.
