Nishiki GOI are ornamental varieties of

the common cart originating in Japan
0:26
these fish have become popular worldwide
0:28
for their beauty and longevity
0:30
understanding their reproduction is
0:31
crucial for maintaining healthy koi
0:33
populations and breeding desirable
0:35
traits the reproductive cycle of koi is
0:38
closely tied to the changing seasons in
0:41
temperate climates koi typically spawn
0:43
once a year usually in late spring or
0:46
early summer as water temperatures rise
0:49
typically between 18 and 24° C koi begin
0:53
to prepare for breeding several factors
0:56
influence COA breeding water temperature
0:58
is the most critical but day length
1:01
water quality and nutrition also play
1:04
significant roles Co need a period of
1:06
Colder temperatures followed by warming
1:08
to trigger their breeding instincts this
1:10
mimics the natural cycle they would
1:12
experience in the wild when conditions
1:14
are right the spawning process begins
1:16
male koi Chase females often nudging
1:19
them to encourage the release of eggs a
1:21
single female can lay up to several
1:24
100,000 eggs the males then release melt
1:27
or sperm to fertilize the eggs
1:29
externally
1:30
KO eggs are adhesive and stick to
1:32
aquatic plants or special spawning mats
1:35
provided by breeders the eggs are tiny
1:38
measuring only about 1.5 mm in diameter
1:41
they're vulnerable to predation even by
1:43
other koi so separation from adult fish
1:46
is often necessary the eggs develop
1:48
rapidly in water temperatures around 20°
1:52
C they hatch in about 4 to 5 days the
1:54
newly hatched fry are extremely small
1:57
and have a yolk sack attached which
1:59
provides new nutrition for the first few
2:01
days of Life a caring for koi fry
2:03
requires attention to detail they need
2:05
clean well oxygenated water and frequent
2:09
small feedings of specially formulated
2:11
fry food as they grow their diet
2:13
gradually transitions to include more
2:16
varied Foods the fry developed their
2:18
adult coloration over several months
2:20
with some colors not fully emerging
2:22
until the fish are 2 or 3 years old
2:25
understanding koi reproduction Cycles is
2:28
essential for successful breeding and
2:30
maintaining healthy Pond populations
2:33
from the annual spawning triggered by
2:35
warming Waters to the careful nurturing
2:37
of tiny fry each stage of the process is
2:40
a testament to the wonders of nature

whether you're a koe Enthusiast or
