prevent

fish

death,


this

water


is


pumped

to
a
biofilter


where


nitrification


bacteria

reside.


There

the


effluents


are


consumed

by

the


nitrification


bacteria.


The
final

product


produced

from

the


action

of


these


specialized


bacteria

is


nitrates


(nutrients)


which

are


a

natural
fertilizer

for


the


plants.
Once

nitrification


is


completed,


the


water


is


circulated


from

the


biofilter


to


the


hydroponic


side


(growbeds)


of
the

system

where


the


plants

reside.


There

the


plants

use

the


vital


nutrients


in


the


water


as

food,


after


which
the

cleansed


water


is


re

-

circulated


back

to


the


aquaculture


side


of


the


system.


Point


of


interest,

the
term
"Aquaponics"

was


created


by

combining

the


words


aquaculture


and

hydroponic

.
Aquaponic

systems

vary


in


size


from

small


indoor


setups


to


large


commercial


operations.


They


can

be

found
in

garages,


basements


and

sometimes


even

in


bedrooms


or


under

carports,


backyards

and

small
greenhouses

right


on

up

to


large


commercial


units

engulfing

acres


of


growbeds


all


under

the


protection


of
large

greenhouses


and

they


all


use

the


same


technology.

The


systems

usually

contain


fresh


water,


but


in
large

commercial


operations

salt

water


systems

may


prove


plausible


depending

on

the


type


of


aquatic


animal
and
vegetation

to


be

produced.


The


science


of


Aquaponics


is


very


definitely


in


it's


early

stages


of
development

and

since


man


is


only


limited


by

his


imagination,


there


is


no

telling

what


miracles


Aquaponics
may

produce

in


the


future.
Putting

it


all

together
Aquaponics

consists

of


two

main

parts


with


the


Aquaculture


part


for


raising


aquatic


animals


and

the
hydroponics

part


for


growing


plants.
The

Components
Although

consisting


primarily


of


two

parts,


Aquaponic


systems

are


composed

of


several


components


or
subsystems

for


the


effective


removal

of


solid

wastes,


effluents


and

to


maintain


water


oxygenation.


They


are
listed

below

in


the


suggested

order


for


which

they


should


be

put


together:
Rearing

tank
Normally,

fish

are


raised


in


aquariums

of


various


sizes


that


accommodate


the


size


of


the


aquatic


animal


and
space
required

for


that


particular

species.


Rearing


tanks


are


basically


any

apparatus


that


has

a

sufficient
depth

and

gallon

capacity

that


can

hold


water.


It

can

be

made


of


glass,


fiberglass,

plastic,


wood


or


a

hole


in
the

ground

lined

with


a

plastic


liner.


Aquaponics


can

be

a

operation

so

utilize

whatever

is
available

to


accomplish


your


end

goal.
