koi fish breeding from por chip to fry
0:02
koi fish with their vibrant colors and
0:05
graceful movements have captivated Pond
0:08
enthusiasts for centuries but did you
0:10
know that these beautiful creatures have
0:13
equally fascinating breeding behaviors
0:15
in this video we will explore the
0:17
intricate world of koi fish reproduction
0:20
from courtship rituals to the care of
0:22
their young koi also known as nishikigoi
0:26
are ornamental varieties of the common
0:28
car originating in Japan these fish have
0:31
become symbols of Good Fortune
0:33
perseverance and transformation in
0:35
Japanese culture their breeding
0:37
behaviors are not only crucial for
0:39
maintaining healthy populations but also
0:41
offer a glimpse into the complex life
0:43
cycles of these aquatic marbles koi fish
0:47
typically breed once a year with their
0:49
reproductive cycle closely tied to
0:51
seasonal changes in most regions
0:54
breeding occurs in late spring to early
0:57
summer when water temperatures rise to
1:00
around 68 to
1:02
74° F this temperature increase triggers
1:05
hormonal changes in mature koi signaling
1:08
the start of their breeding season as
1:10
the breeding season approaches both male
1:12
and female koi undergo noticeable
1:14
physical changes the females develop a
1:17
rounder Fuller appearance as their
1:20
bodies fill with eggs males on the other
1:22
hand develop small white bombs called
1:24
breeding tuberal on their heads and
1:26
pectoral fins these tuberal help males
1:29
grip females during the spawning process
1:32
behavioral changes also become apparent
1:34
during this time male Koy become more
1:37
active and aggressive often chasing
1:39
females around the pond females may
1:41
appear to be running away but this
1:43
behavior is part of their mating ritual
1:46
the chase helps ensure that only the
1:48
strongest and most persistent males will
1:51
have the opportunity to fertilize the
1:53
eggs when a female is ready to spawn she
1:56
will release her eggs into the water
1:58
this process usually occurs in the early
2:00
morning hours the female will swim close
2:02
to the surface often brushing against
2:05
plants or other objects in the pond to
2:07
stimulate egg release male koi closely
2:09
follow the female releasing their Milt
2:11
or sperm to fertilize the eggs as they
2:13
are laid a single female koi can lay
2:16
thousands of eggs in one spawning
2:18
session these eggs are small sticky and
2:21
adhere to plants rocks or other surfaces
2:24
in the pond the adhesive nature of the
2:26
eggs helps protect them from being Swept
2:28
Away by currents or eat by other fish
2:31
unlike some fish species KO do not
2:33
provide parental care to their eggs or
2:35
friy in fact adult koi may eat their own
2:39
eggs and newly hatch fry if given the
2:41
opportunity in natural settings the
2:44
sheer number of eggs laid helps ensure
2:46
that some Will Survive to adulthood
2:49
despite predation the eggs typically
2:51
hatch within 4 to 7 Days depending on
2:53
water temperature the newly hatched fry
2:55
called larvea at this stage are
2:57
extremely small and vulnerable they
2:59
remain remain attached to their egg saxs
3:01
for several days absorbing nutrients
3:03
until they are strong enough to swim
3:05
freely and begin feeding on their own
3:07
several factors can affect the success
3:09
of koi breeding water quality is
3:11
Paramount with clean well oxygenated
3:15
water being essential for egg and Fry
3:17
survival the presence of suitable
3:19
spawning surfaces such as aquatic plants
3:22
or spawning mops can increase the
3:24
chances of successful reproduction
3:27
additionally a balanced diet rich in
3:30
proteins and vitamins for the adult koi
3:33
in the months leading up to breeding
3:34
season can improve the quality and
3:37
quantity of eggs and sperm produced in
3:39
conclusion the breeding behaviors of koi
3:42
fish are a remarkable example of the
3:45
intricate processes found in nature from
3:47
the seasonal timing and physical changes
3:49
to the elaborate spawning rituals and
3:52
development of young every aspect of koi
3:54
reproduction is finally tuned to ensure
3:57
the continuation of these beloved fish
3:59
under understanding these behaviors not
4:00
only deepens our appreciation for these
4:02
living works of art but also helps us
4:05
better care for and preserve koi
4:07
populations for future generations to
