Growing Your Greens (13min)

Aquaponics
a sustainable, food production system that
combines conventional aquaculture (raising
aquatic animals such as snails, fish,crayfish
or prawns in tanks), with hydroponics
(cultivating plants in water) in a symbiotic
environment.
Symbiotic means that
both benefit.
Here
are
the 2
parts:
aquacultu
reeffluent
accumulate
in the water,
increasing
toxicity for
the fish and
this water is
lead to a
system of …
hydroponics
where by-
products from
the aquaculture
are broken
down by
nitrogen-fixing
bacteria
& then filtered
out by the
plants as
nutrients
Clean water goes back to the fish.
Histo
ryAztec
cultivated
agricultural
islands known
as chinampas
for agricultural
use where…
plants were raised
on islands and
waste dredged
from the
Chinampa canals
was used to
manually irrigate
the plants.

South China & Thailand
cultivated and farmed rice
in paddy fields in combination
with fish as early aquaponics systems.
Facilities to Raise
Fish are evolving
Monoculture: Raising single species in structure
Polyculture: Raising two or more species in same structure
Ponds
Most common structure for raising fishNatural PondsManmade Ponds Drainable Must be built near a water
supply
Race
ways
Manmade tanks (indoors or
outdors)Usually made of concrete
Must be near a water
sourceCommon in fish hatcheries
Exa
mple
s:
Rectangular shaped, commonly 5:1 (or greater) length to width ratio
Average depth of 3- 5 feet
Constant water flow to eliminate areas of poor circulation
Silo
s
Deep cylinder tanks,
similar in operation to
horizontal racewaysConcrete, plastic, etc.
Have less surface area
than racewaysEasier to fit into operation
Cages
Use existing water sources (pond), but enclose the fish in a cageCheaper initial
investment that other
set ups

We’ll begin with a simple
system this year and
hopefully lead to one in
the ground.
What is in the soil component is critical to success…

*You MUST provide bright light close to the flat, or the babies will grow long and spindly and flop over. We're talking only 1-2" above the plants! Don't skip past this bit of advice! Bright fluorescent lighting creates thick, short, stocky, healthy seedlings.
