Cooperative Extension in Hancock County

4-H Aquaponics Project

University of Maine Cooperative Extension 4-H in partnership with the UMaine Center for Cooperative Aquaculture Research (CCAR) and the UMaine Aquaculture Research Institute (ARI) delivers the 4-H Aquaponics Project, a project-based learning experience for K-12 youth. The project teaches learners about the biology, chemistry, and engineering of sustainable aquaponics systems, with a focus on plant and fish husbandry. Participants develop valuable life skills such as record-keeping, problem-solving, food safety, collaboration, math, and science literacy.

The project is open to educators and youth in both formal (classroom) and informal (summer camp, after-school, library, community) settings. Thanks to our generous sponsors, participation is entirely cost-free for educators in Maine.

What is Aquaponics?

Aquaponics is a unique farming method that combines raising fish in tanks (aquaculture) with growing plants without soil (hydroponics). In an aquaponics system, plants utilize nutrient-rich water from the fish tank, simultaneously purifying the water for the fish. This sustainable farming technique can be practiced year-round, indoors, and in any climate, making it a safe, easy, and fresh way to grow your own food. We believe aquaponics is an engaging hands-on platform for teaching STEM concepts related to aquaculture across various age groups.

How to Participate

1. Register – submit the form below and a member of our team will reach out to you.
2. Receive materials – we will deliver equipment directly to your classroom and assist with set up and orientation.
3. Start learning – we provide activity and lesson plans to guide you and your learners through the project.

No prior experience with aquaponics is necessary!

Support and Expectations

In exchange for your participation, we provide the following support to address common challenges faced when maintaining tanks in educational spaces:

• All equipment is supplied at no cost, including fish and live plants/seeds.
• Learning modules and activities are included.
• Fish can be returned to us when care is not possible (e.g., during summer or winter breaks).
• We offer assistance with system setup and fish tank cycling, including site visits.
• Troubleshooting support is available for any equipment or fish health issues.
• Direct access to aquaculture experts and youth development professionals at UMaine.

In return, we ask participating educators to:

• Facilitate the project-based learning experience with their youth.
• Take responsibility for the care and maintenance of plants, animals, and equipment.
• Maintain frequent communication with us about needs, issues, and successes.
• Provide feedback on ways to improve the project.
• Return equipment when it is no longer in use.
• Report the number and demographics of youth participants (anonymously) reached through the project.

FAQ

What ages or grades is this project designed for?

The Aquaponics Project is suitable for a wide range of ages. While our curriculum is designed for upper elementary/middle school age, it can be adapted to any age group. We offer support for customizing the curriculum to your specific learners. We have worked with kindergarten through high school educators through this project.

What learning environments are best suited for this project?

We welcome educators from diverse backgrounds, including formal classroom teachers and informal educators such as camp counselors, 4-H volunteers, librarians, and more. We will work with you to tailor the project to your learning environment and available time with your learners. That being said, the project works best in an environment where a 20-30 gallon fish tank can be placed securely indoors, with access to electricity and water (although it doesn’t need to be right next to the sink or water source). We also need a commitment from an adult to assume responsibility for the equipment, plants, and animals in the ecosystem. Participating educators are expected to facilitate the project activities with their learners with support from the project team.

I already have a fish tank in my educational setting. Can I use it for this project?

Absolutely! We frequently collaborate with educators who already have some basic equipment. We’ll assist in filling in any missing elements and guide you toward best practices for aquaponics fish and plant care.

How long does the project take?

The program’s duration is flexible and can be completed at your own pace. It can last for an entire school year or a shorter timeframe, depending on your group’s needs. Here is a typical timeline for reference:

Start of project, Month 1: Meet with the project team, do a site visit, set up the fish system (fish tank)

Months 2-4:  Cycle fish tank, youth submit proposals for their aquaponics design, project team gives proposal feedback

Month 4: Add fish to tank, start to build the grow bed/plant system, sow seeds

Months 5-6: First harvest of produce

Month 6 and beyond: Run and maintain the aquaponic system

I live out of state, can I still participate?

The 4-H Aquaponics Project is currently only open to Maine youth and educators. However, we occasionally offer virtual learning aquaponics programs through the 4-H Virtual Learning Hub which are open to youth nationwide. If you are a 4-H’er in another state, you can reach out to your local county 4-H staff about starting an aquaponics project. We are happy to provide digital resources if needed!
