and
dart


into

the


nest


as

they


attempt


to


fertilize

the


eggs.


They


then


quickly

dart


away.
The

size


of


the


female


plays


a

large


role

in


how


many


eggs

will


be

produced.


A

small


female


can

produce

as
few
as

1,000


eggs,


and

a

large,


healthy


female


can

produce

up

to


100,000

eggs.


The


male

continues


to


watch
over

the


nest


until


the


larvae


are


able


to


hatch


and

swim

away


on

their


own.


The


bluegill


generally

begins


its
spawning

career


at


one

year


of


age,


but


has

been


found


to


spawn


as

early

as

four


months


of


age

under
favorable
conditions.


Anglers


find

spawning


season


to


be

a

very


successful


time


to


fish

for


bluegills,


as

they
aggressively
attack

anything,

including


a

hook

that


comes


near.
Japanese

KOI
Koi

are


among

the


longest

-

living


vertebrates


known


to


man


with
some

living


over


200

years


and

now


they


are


being


raised
worldwide

in


Aquaponic


systems.


The


most


popular


category


of
Koi

is


the


''Gosanke'',


which

is


made


up

of


the


Kohaku


(Nishikigoi),
Taisho

Sanshoku,


and

Showa

Sanshoku


varieties


and

their

is


a

much


larger

than


can

History

-


The


carp


is


a

large


group

of


fish

originally


found


in
Central

Europe


and

Asia.


Asian


carps


were

originally


domesticated
in

East


Asia,


where


they


were

used

as

food


fish.


The


ability

of


carp
to

survive

and

adapt


to


many


climates

and

water


conditions


allowed


the


domesticated


species


to


be
propagated
to


many


new


locations


including


Japan.


Natural


color


mutations


of


these


carp


would

have
occurred

across


all


populations.


Carp

were

first


bred


for


color


mutations


in


China

more


than


a

thousand

years
ago,

where


selective


breeding


of


the


Prussian


carp


led


to


the


development


of


the


Goldfish.


Carp

are


known


as
Koi

in


Japan.


Of

the


various


domesticated


carp


species,


the


common


carp


is


one

of


the


more


commonly

used
in

Aquaculture.
The

common


carp


was


grown


as

a

food


fish

at


least


as

far


back

as

the


5th


century


in


China.


Common

carp
were
first


bred


for


color


in


Japan


in


the


1820s,


initially


in


the


town

of


Ojiya


in


the


Niigata

prefecture


on

the
North

Eastern


Coast


of


Honshu


Island.


By

the


20th


century,

a

number


of


color


patterns

had

been


established
most

notably


the


red

-

and-

white


''Kohaku''.

The


outside


world


was


not


aware


of


the


development


of


color
variations

in


Koi


until


1914,


when


the


Niigata

Koi


were

exhibited


in


the


annual


exposition


in


Tokyo.


At


that
point,

interest


in


Koi


exploded

throughout


Japan.


The


hobby


of


keeping


Koi


eventually


spread

worldwide.


Koi
are

now


commonly

sold


in


most


pet


stores,


with


higher

-

quality


fish

available


from

specialist


dealers.
Hybridization

-


Extensive


hybridization

between


different


populations

has

muddled


the


historical


zoo-
geography

of


the


common


carp.


However,


scientific


consensus


is


that


there


are


at


least


two

subspecies


of


the
common

carp,


one

from

Western


Eurasia


and

another


from

East


Asia.
