About Hapa Farms
Innovative Aquaponics • Sustainable farming • Minimal resource requirements • Utilize marginal farm lands

Aquaponics in Schools • I’m a farmer • Designed, implemented, and built
aquaponic programs for schools • Partner with isisHawaii and Dr. Clyde
Tamaru’s lab (CTAHR)

Goal of Aquaponics in Schools
Self-sustaining program: • Independent maintenance of healthy
systems by school faculty, staff, students, parents
• Teachers have a good understanding of science behind aquaponics to develop curriculum
![Page 5: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/5.jpg)
Considering Aquaponics? • Many dive straight into building an
aquaponic system without the proper preparation and understanding of what is involved – This can lead to becoming overwhelmed after
the system is in place
• These are some things to consider before you get started (or work on now if you already have a system but haven’t addressed these points)
![Page 6: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/6.jpg)
Involvement & Investment • Aquaponic system care is a 7 day/week
job – no holidays or weekends! • The more that are involved with the care &
maintenance, the better – Science, Social Studies, Economics, English
teachers – Maintenance staff – Administrators – Parents – Don’t limit yourself

Site Preparation
• Ground prep – Gravel/cement
• Electrical outlets • Water/sinks • Fenced enclosure
– Security – Safety (City Bldg Code §3109)

Materials Selection
• Everything that touches the system should be food safe
• What’s safe & what’s not is always being debated but a recent study at Goethe University in Frankfurt found that PET leaches hormone-disrupting chemicals into water
![Page 9: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/9.jpg)
System Build • Build your own system, don’t have it built
for you • Everyone that will be involved should help
with the system build – Starts investment in system(s) – Provides deeper understanding of how the
system works

So now you have an aquaponic system…
• Many different possibilities • With a little bit of creativity you would be
amazed with what you could do with your system(s)

Beyond the Basics
• As you get creative & explore what you can do with aquaponics, you will inevitably have questions and run into problems
• There are so many people doing aquaponics now but rigorous scientific research is relatively new and rare – This can lead to conflicting information
• Here are a few common myths and problems that I’ve run into with schools…
![Page 13: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/13.jpg)
Myths
• All poop is the same • Can’t grow some plants because they
don’t like “wet feet” • Vegetables from system taste fishy • Want to get rid of all the poop in my
system
![Page 14: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/14.jpg)
Common Problem 1
• Problem: Grow space becomes a premium
• Solution: Add on low-cost static hydroponics or static aquaponics, or expand in-ground using aquaponic water for fertilizer
![Page 15: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/15.jpg)

Common Problem 2
• Problem: I don’t like tilapia • Solution: Try it! Or try to use a different
fish (like Pacu)
![Page 17: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/17.jpg)

Common Problem: (Lack of) Attention to Food Safety
• I’ve seen a lot of practices at schools which I would deem unsafe from a food safety standpoint
• It will just take one suspected incident of food-related illness traced to an aquaponic system for aquaponics to be eliminated from schools statewide

Importance of Food Safety
• Salmonella, E. Coli O157:H7, Rat Lungworm Disease
• In June, E. Coli O145 outbreak sickened 14 adults and killed a 21 month old baby
![Page 21: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/21.jpg)
Food Safety
• Can be a relatively inexpensive process • Does not need to be implemented
immediately but should be kept in mind throughout planning, prep, and build
![Page 22: Best Practices & Lessons Learned for Aquaponics in Schools](https://reader035.vdocuments.net/reader035/viewer/2022081623/613d7572736caf36b75d9331/html5/thumbnails/22.jpg)
Good Agricultural Practices • Avoid contamination from feces of warm-blooded
animals – No overhang over systems – No clutter in enclosure
• Avoid contamination from slugs – No plants touching ground (i.e. no path for slug between ground
and system) • Water from system shouldn’t touch plants • Two sinks
– One designated for hand washing only • Signs of rules • Educate everyone in contact with system of food safety
rules

In Conclusion…
• I’m not trying to scare you - aquaponics is safer than ground farming
• Provides hands-on learning experiences for students incorporating STEAM values and active, movement-based learning
• Applications in curriculum are endless
