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.

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

hopefully lead to one in

*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.
