Aquaponics
Growing Fish and Plants Together
Presented by: JD Sawyer
Aquaponics Defined
The integration of:
Aquaculture – Growing fish in a re-circulating system
Ponos – The Greek word for growing
plants with or without media
Most people relate growing plants to hydroponics since both use nutrient rich water and both use soil-less media.
How Aquaponics Works
1. Fish are raised in a tank
2. Water from the fish tank is pumped to the plants
3. Bacteria convert ammonia and nitrite to nitrate
4. Plants absorb the nutrient rich water
5. Filtered water is returned to the fish tank, clean
Fish are Happy!
Plants are Happy!
We get more to eat!
Why is it Considered Sustainable?
Waste from fish is used to feed the plants
Fish and plants create a polyculture producing two products
Water is re-used in the re-circulating system
Local food production, enhances the local economy and reduces food transportation
Continuous organic fertilizer
ATTRA – National Sustainable Agriculture Information Service
Why Aquaponics?
Uses a fraction of the water, about 10% of soil growing
No need to purchase, store and apply fertilizer
No soil-borne diseases, no tilling, no weeds
Grow two food products together, protein and produce
High fish stocking density, high crop yield
No waste – hydroponics waste solution, aquaculture waste fish solids – aquaponics all waste is used
No pesticides or herbicides, only fish fertilizer
Food security, grow your own food, indoors, year-round
Works in draught or places with poor soil quality
Water use comparison
Open-water net pens—“Infinite” number of gallons per pound of
production
Non-recirculating raceways and tanks—5,000 to 10,000 gallons per pound of production
Non-recirculating ponds—500 to 1,000 gallons per pound of production
Recirculating systems—5 to 10 gallons per pound of production
Integrated aquaponics—Wastewater directed to greenhouses; no discharge

Pros
Work great for most hobby aquaponics
Easy to find components, easy to build
You can grow lots of different plants in one system
Make as big or small as you want
Cons
Can build-up anaerobic zones
May need to be cleaned out occasionally (or use worms)

Growing Power Model
• Non-profit based in Milwaukee, WI
• Founded and run by Will Allen
• Won the MacArther Genius Grant
• Uses multiple tiers over long trough fish tanks
• Water acts as Thermal Mass
Pros
Good for community sized systems
Easy to find parts,
get volunteers to build
You can grow lots of different plants
Use of vermicompost adds lots of additional nutrients
Cons
Can build-up anaerobic zones that need cleaned
Water dark due to plants
potted in vermicompost
Could benefit from solids filtration, can’t see fish
Raft Method
Method researched and developed at University of Virgin Islands
Research and commercialized by Nelson and Pade, Montello, WI
Small-Scale Raft Systems
Chicago High School for Agriculture Science (CHAS)
Personal-sized raft systems
Raft Method
Pros
Great for commercial setups
Very high yield of both fish and plant crops
Small system – 100 lbs of fish, 925 heads of lettuce
Big system – 7,500 lbs of fish, 194,400 heads of lettuce
Typically installed inside a greenhouse (although in tropical locations they are outside)
Cons
Requires more extensive filtration methods
Usually grows a specific crop like lettuce or basil
Sweetwater Organics, WI
Nutrient Film Technique
Pros
Materials readily available
More precise growing conditions
No concerns for pH changes related to media
Cons
Requires more
filtration
Doesn’t allow as many crop options

Fish inputs and outputs
Inputs: Feed Oxygen and Water
Outputs: Urine (water), Ammonia, Carbon Dioxide, Feces, Uneaten Feed
Water Recirculation Cycle
Fish tank >> Solids Removal >> Biofiltration >> Aeration/Oxygenation
Keeping Fish Healthy
pH – Most fish like pH between 6-8
Ammonia and nitrites are very toxic to fish
Nitrates are fairly safe for fish (and great for plants)
Fish need oxygen (they can die in 30 min. without it)
Battery based aerators are available for power outages
Drastic temp changes can cause health issues and
death
Sensitive to light (avoid direct light)
Importance of Temperature
Do not exceed temp changes of more than 3F per day if possible
Fish can not regulate their body temperature like humans do
They are dependent on the water temperature for their
body temperature
Temperature and growth rate
CMAX= Max. feeding rate
SDA = Digestion (specific dyna
action)
F = Feces, urine production (egestion)
U = Ammonia production
(excretion)
ΔB = Change in fish weight
Opt. coolwater temp. = 23 C (
R = Respiration
Max. = 28 C (82 F; starvation)
Coldwater fishes = 14-16 C (57
F)
Warmwater fishes = 28-30 C ( 86 F)

Tilapia
• Commonly used in aquaponics
• Warm water fish (74-78*)
• Tolerates pH shifts, temp changes, high ammonia, and low dissolved oxygen
• Omnivorous – pellet fish food, duckweed, veggies from the system
• Grows to plate size in about
6-9 months (ideal conditions)
Yellow Perch
Good for re-circulating systems
Likes cooler water (68-74*)
Tolerates lower dissolved oxygen, adjusts to pH changes
Eats common pellet fish foods and veggies
Grows to plate size in about 9
months
Trout
More challenging to maintain
Likes colder water (64-68*)
Can be carnivorous and will eat smaller fish
Requires high dissolved oxygen levels
Sensitive to pH changes and water quality
Eats pellet fish food
Reaches plate size in 12-16 months
Bass, Bluegill, Catfish
Often raised in ponds, can be raised in re-circulating system
Like temperature around 80*
Eat pellet foods, bottom feeders
More sensitive to temp, pH and water quality
Bass harvest 15-18 months
Bluegill harvest 12-16 months
Catfish harvest 5-10 months
Koi, Goldfish, Carp
Great pond fish
Popular if you don’t like to eat fish
Koi are fancy (expensive) carp
Tempature 65-75*
Omnivorous – flake or pellet foods, bugs, plant roots
Sold for “pets” or to show based on color, shape and scale patterns.
Fish Health Management
Always exercise good hygiene and biosecurity— prevention, avoidance, selective access, and common sense.
Quarantine fish from other facilities before stocking them in your system. Monitor their health for several days—treat if necessary.
The best defense is your fish’s own immune system. Provide a low-stress environment and your fish will maintain their health.
Fish Maintenance
Feed fish 2 - 3 times a day, but don’t overfeed
Fish eat 1.5 – 2% their body weight per day
Only feed fish what they can eat in 5-10 minutes
Fish won’t eat if they are too cold, too hot or stressed
Check water quality, add water or do partial water changes if necessary
Observe fish behavior and appearance
Some fish become “social” and will “greet you”
Think like a fish, “What would make you happy?”
Fish Feeds
Commercial fish feeds contain exact protein, carbohydrate and other vitamin requirements for specific fish
Plant based proteins can include soy meal, corn meal,
wheat meal etc…
