koi fish and braish water Factor fiction
0:03
KO fish with their vibrant colors and
0:05
graceful movements have captivated Pond
0:08
enthusiasts for centuries but can these
0:10
beautiful creatures truly thrive in
0:12
brtish water today we're diving into
0:15
this intriguing question to separate
0:17
fact from fiction first let's understand
0:20
what brackish water is brackish water is
0:22
a mixture of fresh and salt water
0:25
typically found in estuaries where
0:27
rivers meet the sea it has a salinity
0:29
level between that of fresh water and
0:32
Marine environments Co fish
0:34
scientifically known as cyonus ruof
0:37
fuscus are a domesticated variety of the
0:40
common carp in their natural habitat koi
0:43
are freshwater fish originating from the
0:46
rivers and lakes of East Asia they have
0:48
evolved over thousands of years to
0:50
thrive in these freshwater environments
0:52
the physiology of koi fish is
0:54
specifically adapted for life and fresh
0:56
water their gills and kidneys are
0:57
designed to maintain the proper balance
0:59
of salt and water in their bodies a
1:02
process called osmo regulation in
1:04
freshwater fish constantly absorb water
1:08
through their gills and skin and their
1:10
kidneys work to produce dilute urine to
1:13
expel excess water now let's address the
1:16
misconception that koi can thrive in
1:18
brackish water while koi are known for
1:20
their hardiness and adaptability they
1:22
are not naturally equipped to handle the
1:25
increased salinity of brackish
1:27
environments their osmo regulatory
1:29
system is not designed to cope with the
1:31
higher salt content found in brackish
1:34
water exposing koi to brackish water can
1:36
lead to several health issues The
1:38
increased salinity can cause dehydration
1:40
as the fish's body attempts to balance
1:43
its internal salt concentration with the
1:45
external environment this can lead to
1:47
stress decreased immune function and
1:50
even organ failure if prolonged
1:52
additionally brackish water often
1:55
contains different types of bacteria and
1:57
parasites that Ko's immune systems are
1:59
not accustomed to fighting this can make
2:01
them more susceptible to diseases and
2:04
infections it's important to note that
2:06
while some fish species can transition
2:09
between fresh and brackish water koi are
2:12
not among them species like salmon or
2:14
eels have special adaptations that allow
2:16
them to move between these different
2:18
environments but koi lack these
2:19
capabilities so to answer our initial
2:22
question can koi fish thrive in brackish
2:25
water the answer is a clear no koi fish
2:28
are freshwater species and cannot thrive
2:31
in brackish environments while they
2:32
might survive for short periods in
2:34
slightly brackish conditions long-term
2:37
exposure would be detrimental to their
2:39
health and well-being for koi owners and
2:41
enthusiasts it's crucial to maintain a
2:44
proper freshwater environment for these
2:46
fish this means keeping the water
2:47
parameters within the appropriate range
2:49
for koi including a PA between 7 and 8.5
2:53
and ensuring the water is free from
2:55
contaminants and excessive minerals in
2:57
conclusion while koi fish are indeed
2:59
hearty creatures they are not suited for
3:02
life in brackish water to ensure the
3:04
Health and Longevity of these beautiful
3:06
fish it's best to keep them in the
3:08
freshwater environments they've adapted
3:10
to over Millennia by providing the right
3:13
conditions we can enjoy the beauty of
3:15
koi fish for years to come
