koi breeding you need to know 2019

koi breeding

koi breeding tips that will make you breed koi fish successfully

koi breeding This is my personal experience on  how to breed koi fish.

I had also included the actual koi breeding step by step videos that I had done in koi breeding.

The videos start with identifying the koi fish genders down to hatching and caring and raising koi fry.

The most important part is to identify koi fish breeder gender check out the video below

How can you tell if a koi fish is male or female?

A mature male koi will have a slender looking body, while a female koi will have a rounded body,

particularly when it’s spawning season and she’s carrying a nest full of eggs! Next, examine your koi’s fins.

A male koi’s pectoral fins, the ones near his head, will appear pointed and solid in color

 

Also, check the male breeders if they are ready to be breed by checking if they have enough milt and sperm watch video below on how to do it.

 

 

koi breeding setup 

My koi breeding setup is simple DIY breeding koi pond tank and the materials I used are bamboo for the koi pond frame and Trapal for the liner.

how old do koi have to be to breed

Koi fish are sexually matured when they are about 1-year old already but it is not advisable to breed them at young age

Why? because the membrane of the female egg is thin yet and the outcome is high mortality rate of the koi fry,

It is hard to determine koi fish age if you just bought it from somebody else or at the pet store, since sizes will not determine koi fish age,

because koi fish that are placed in smaller koi pond grows slow, so tendency some will breed even if their sizes are small because of their age are sexually matured already.

 

How long is a koi fish pregnant?

Koi do not get pregnant and are not live-bearers. Koi fish typically mate in warmer water in the spring or summer seasons.

There is no timeframe how long will the female koi fish developed eggs. What you can do is isolate the female koi fish breeder.

This will make the female koi fish breeder to store and develop eggs.

You can tell if the female koi fish breeder has enough eggs already by looking at its abdomen.

The female koi fish breeder abdomen will be swollen

The mating period lasts about two to three days in which the female lays the eggs upon various surfaces while the male shortly after fertilizes them.

 

how often do koi fish lay eggs

Normally koi will breed once a season on Countries that have four seasons usually spring time.

Why, because during springtime the temperature is warm and foods are abundant.

but not always, sometimes it will take warmer water and sometimes colder water.

Sometimes a sudden change in water temperature and water chemistry stimulate them to spawn.

Once instance to prove this is I transfer my large female koi to the breeding tank with cooler water

and when I check her in the morning it had spawn that night already.

It did make for a mess in her show tank. Some will spawn twice in a year, some won’t and even skip a year.

Some breeders will induce spawning so that they can develop fry on a schedule.

I always do this though I am not using an artificial breeding method controlling environment works for me.

I isolate the female from males and condition both the female and male koi fish breeder

I can breed my koi fish the whole year round since We don’t have four season here in my place.

Some koi will spawn later in the year but for the most part the farms time to a part of the season to keep their whole operation running on a schedule.

What age to breed koi?

A Koi’s prime mating age is between 3-6 years old, but koi have also been able to produce baby koi fish until they are up to 15 years old.

Make sure to give your breeding koi couple some privacy when it’s time for them to mate. Koi need a place to lay their eggs.

How long does it take for koi fish eggs to hatch?

Your koi eggs will hatch around 4 days after they are fertilized for colder Countries. 2 days for Tropical warmer Countries.

They will then attach themselves to structure like the side of the tank or pond for 2-3 days where they will be feeding off their yolk sac.

 

Is my koi fish pregnant?

However, your koi will appear bloated and pregnant for up to several days before she’s ready to release her eggs.

At this point, you could still stop the spawning from happening if you don’t want eggs or baby fish (fry)

in your pond by simply removing the females from the pond, keeping them separate from the males.

 

koi breeding Separate the female koi fish breeder for conditioning 

Separate the female koi fish breeder from male koi fish breeders. Why? It will help ensure the female koi fish breeder to develop more eggs.

If female koi fish breeder is mixed with male koi fish breeders in the community pond.

The males will mate her without your knowledge, so the female koi fish cannot store enough eggs on its tummy.

Here is a photo of a koi fish female breeder prior from separating and conditioning

Watch the video here 

Feed your female koi breeder and male koi fish breeder high protein koi food pellets.

Feed your koi fish breeders plenty of live foods and vegetation

Watch video here

Live foods for koi fish 

  • Daphnia
  • Earth worms
  • Snails
  • Tubifex
  • Shrimp

List of vegetation that koi fish loves

  • duckweed
  • green pea
  • wheat germ
  • lettuce
  • water melon
  • azola

 

Observe the female koi fish breeder body specifically her tummy region if it became swollen already.

This is your indicator if the female koi fish is ready to spawn

You can also apply a gentle pressure in its ventral area if the tummy is swollen already if there are eggs already.

The eggs will come out if it is ready to spawn.

One indicator also is the tummy region is soft when touch.

And you can also watch the video here

 

 

Preparing the koi pond for breeding 

  • I change the water 60 % and leave the water dripping slowly this will stimulate them to breed too.
  • Add nesting media I created a floating yarn and net

 

how do koi fish mate

The male koi fish will chase the female koi fish and bump its abdomen to the pond wall or nesting media.

Adding the koi fish breeders 

I add the koi fish together at 6 pm in the evening and note this was also done at the full moon.

I check them at 12:00 midnight if they already breed but there was no koi breeding sign yet,

a breeding sign is female will gather the nesting media and seems like creating bubbles and males will chase her,

so I just leave them and then when I wake up at around 5:00 am in the morning they are already chasing and breeding here is the actual video of them breeding watch koi fish actual video breeding 

Remove the koi fish breeders after they are done mating.

You will notice if they are already done mating when the males no longer chase the female koi fish breeder.

You need to remove them fast immediately because after laying eggs they will start eating their eggs.

Then perform 60% water change this will prevent water to be foul because of the sperms.

in koi breeding you must always prepare methylene blue for protecting the eggs.

Place methylene blue to prevent the molds attacking the eggs.

how fast do koi fry grow this will depend on the temperature of the water the climate the faster they grow because warmer temperature stimulate their metabolism and this will trigger them to eat fast.

What do koi fish eggs look like?

Koi like to lay their eggs on pond plants, spawning mats, or spawning ropes. … Koi eggs are tiny and translucent.

They can range from milky white to yellow or green. After the next two days, the koi fish eggs will hatch

Here is a video of a koi fry growth chart watch it here

 

koi fry growth rate in the first week from hatching their sizes are about 1 cm and their koi fry color are all yellow yet.

you can watch this video of my 1-week old koi fry

how fast do baby koi grow to depend on the temperature, size of the pond and sources of live foods.

If you feed them daily with live foods they grow too fast also if your temperature is warmer they tend to feed more in warmer temperature because warm climate makes their metabolism fast, so they get hungry all the time.

koi eggs hatching depends on the temperature here in my place which is tropical and warm koi eggs hatch in 2 days in colder region koi eggs hatch for 7 to 10 days.

I was not able to remove the tobi koi fry and last week also the water quality was degraded because some of the clams died and also their pooh increase already since they are growing to watch the video below

 

 

Here is an article about Tobi koi fry from http://www.raingarden.us

THE NATURE OF TOBI
Steve Hopkins
Rain Garden Ornamentals
June 2007
Anyone who breeds koi knows about tobi. In other species these are often called “shooters”.

They occur in goldfish spawns too. They are the fry that grow to juvenile size very quickly.

They are noted for eating their smaller siblings.

Most tobi koi do not have the refined characteristics the breeder is looking for, although some do.

I have never seen a good explanation of how and why tobi develop.

If anyone knows of an authoritative description, please let us know. Until then, I will give you my off-the-wall
theory about tobi.

I think tobi are hard to explain because there are two factors at work, genetics and blind luck.

Genetics: Koi and goldfish carry in their genetic code remnants of everything that come before.

A top-notch pair of gosanke or ranchu carries all the genetic material needed to make the ancestral common carp or crucian carp from which they were derived through selective breeding.

They also have all the genetic material needed to recreate the incremental steps in their evolution.

In the offspring from a pair of sanke you will find kohaku, higoi and perhaps even a magoi.

A group of ryukin offspring may include individuals with characteristics of wakin and common goldfish.

The more ancestral forms are always more hardy.

Left to their own devices and allowed to breed indiscriminately for many generations, a population of koi will revert
back to something resembling the ancestral common carp and goldfish will revert back to something resembling a crucian carp.

In a group of sibling fry, those with a more primitative genetic make-up will be just a little bit stronger and faster giving them a slight advantage when it comes time to eat or avoid a predator.

But, in the world of fish fry, a slight advantage can become amplified many fold.

There is a snowball effect. A fry that gets just a little bit bigger than its siblings is better able to
capture and compete for food so it grows faster.

The larger the size disparity, the bigger the advantage. So, over just a few weeks time an individual that is just slightly
larger than its siblings becomes ten times larger than its siblings.

At some point, the size disparity becomes so great that the larger individual can eat its siblings providing it
with a new limitless food supply.

The snow ball effect escalates. Blind Luck But, how can some tobi be excellent examples of highly refined koi or goldfish and show no signs of being a throw-back to an ancestral form?

I think it is because there is a blind luck factor at work as well.

Imagine a group of larvae which have absorbed their yolk sack and are ready to begin feeding.

Perhaps some arrive at this stage a few hours ahead of the rest because they were spawned first or their position on the spawning substrate was a fraction of a degree warmer then the rest, or because of some other factor.

The larvae instinctively dart at a moving food particle.

Some times they catch it and sometimes they miss.

They are growing extremely rapidly and catching one or two extra choice food morsels can make a difference in that growth rate.

Some individuals are just lucky and are able to get a tiny bit ahead of their siblings.

As described above, a very small advantage can quickly snowball into a large advantage.

An individual with no innate genetic advantage can become a tobi just through bind luck.

Another Observation In some batches of fry the size distribution is large and there is an unusually large number of tobi.

In other batches the size distribution is narrow and the siblings look almost identical.

In general, the better the fry are fed the less variation there will be in their size.

If abundant live food can be kept in front of the fry at all times while maintaining good water quality, there is a much lower incidence of tobi.

Under the best of conditions the growth of fry is phenomenal and most of the population (except for those with serious deformities) has the potential to grow at the rate of tobi.

The best way to minimize the number of tobi is to provide better nutrition and husbandry.

The biggest and best koi and goldfish will have had the best nutrition and water quality their entire lives.

Periods of less than optimal conditions can have long-term effects.

In extreme cases, we say that the fish is stunted.

The younger the fish, the more severe and lasting the effect of poor nutrition and water quality.

Tobi are considered by most to be undesirables.

If they are genetic throw-backs then they probably are undesirable. However, you should be on the look-out for those fish

which have both the genetic potential to meet your selection criteria and the good luck to have gotten off to a fast start in life and become a tobi.

It is always a good idea to separate tobi if you can; especially if they have become large enough to be cannibals.

But, do not automatically assume they have no potential.

Protecting koi from Herons. Herons are beautiful, majestic birds that have one major flaw.

Herons love to feast on Koi, and where better than to find Koi fish then an unattended Koi pond or garden?

When you first notice a Heron in your garden, you may not even think of these birds as a danger.

Herons are 2 or 3 feet tall, with an extremely large wingspan.

They appear to be extremely graceful until you realize that the
beautiful sight you were just looking at could have potentially been a thief caught in the act.

If you noticed that your fish are missing in action, chances are a Heron is to blame.

You may even notice large gaping holes in the sides of your Koi.

This happens when a Heron attempts to catch one of your Koi fish, but does not get a good grip on it.

The other will notice their Koi laying on the lawn several feet away
from the pond, which is the result of a Heron dropping the Koi after removing it from the pond.

While nothing can completely stop this from happening, you can
do a few things to detour Herons from eating your pride stock of Koi.

While there are many types of technical equipment available to
attempt to detour Herons, you will quickly find that these types of
detours will only work for a small amount of time.

Protecting koi Some pond owners place a fake plastic Heron into their garden.

This is supposed to detour another Heron from landing there.

This works for parts of the season until the mating season comes.

Herons will be more likely to land near your plastic Heron when they are looking for a mate.

Various other types of equipment attempt to detour Herons by causing them discomfort.

This only works until the Heron get used to it, or just finds a way around it.

The only way to protect your Koi is by watching out for them.

A few simple things will not prevent Heron from visiting your
pond, but it will greatly reduce the presence of them.

Constantly change your routine. Herons are smart and know when you will typically be present.

Visiting your pond frequently at various times during the day will
greatly increase the chance that you will catch the Heron in action.

If you are unable to vary your routine, you may consider enlisting others to visit your pond as well.

Older, trustworthy children in the neighborhood may delight in
visiting your pond at various times of the day.

Giving them permission to visit whenever they want will allow
others to visit when you are unable too.

If you catch a Heron in the act, make as much noise and frighten the Heron as much as you physically can.

Shout, yell, throw things, or whatever you feel will scare the Heron.

The more frightened the Heron is, the less chance he is to return anytime soon.

Protecting koi Create a hiding place in your pond for your Koi fish.

More natural Koi pond owners have noticed that after a Heron
attacks a pond, it may seem that the Heron has got all the fish, only
to notice that the Koi start appearing from strange hiding places once the scare is over.

If you purposely provide a place for your Koi to hide in the event of
an attack, you greatly reduce the amount of fish that a Heron will leave with.

Do not worry about your Koi hiding from you, as they should know and trust that you will not hurt (or eat) them.

Do not restock your pond right away in the event of a Heron attack. Waiting to restock may send the Heron searching for new feeding grounds

How do you protect koi from predators?

Get Your Pet Dog to Help Protect Koi. Your guard dog, when trained to stay by or anywhere near the pond, can effectively scare away predators. …
Use Decoys Wisely. …
Install Motion-Activated Sprinklers or Alarms. …
Give Your Koi Safe Hiding Places.

How do I get rid of herons?

Place fish tunnels at the bottom of the pond. …
Install an alligator decoy in the pond. …
Fill the pond with the maximum amount of water possible.

What is the best heron deterrent?

All the below recommendations will help heron proof your garden pond and provide extra protection for your pond fish.
1) Pond Netting.
2) Koi and Goldfish Shelter.
3) Electric Pond Fencing.
4) Automatic Heron Sprinkler.
6) Blue Heron Decoy.
7) Alligator Decoy.
8) Mirrors or reflective surfaces.

koi fish transforming into a dragon 2018

koi fish turning into dragon

koi fish turning into dragon

koi fish turning into dragon This is my diorama video telling the
story of the legend of the koi fish transforming into a dragon

Once upon a time, there was a little Kohaku koi fish who lives in a beautiful small pond.

One day He decided to go in the dragon’s gate because he wanted to
become a dragon as what he heard his grandfather told him that
whenever you will succeed in reaching the dragon’s gate you will
turn into a beautiful dragon,

so the little kohaku koi fish jump out of his pond and swim towards
the dragons gate when He was about to reach the summit of the
water fall the Gods test him they make large waves to prevent the
koi fish from reaching

the dragon’s gate but the little koi fish is determined to reach the
top He keeps on swimming even if he was already tired and
exausted and then the Gods throw him ball of fires and even lighting

but this did not stop the little kohaku koi fish he continues to swim
upward the water fall and then successfully reach the dragon’s gate. The Gods were very pleased with the little koi fish that they turn the little koi fish into a beautiful dragon.

My story is based on Fish in Chinese mythology

Here is also a story from this site http://www.egreenway.com/dragonsrealms/DT3.htm

The Threshold of the Dragon’s Gate

“Beneath the serene quiet of the water lilies a young carp senses a calling . . . swelling up in her heart
like the swirling waters at the base of a great waterfall,

Somehow summoned to go beyond the barrier of crashing water and veiled mist

The churning waters of the waterfall’s bottom matches that of the young carp’s desires

Finally with a burst of enthusiasm the carp has launched herself up
the wall of rushing water cresting the first fall with a surge of effort
only to be met with relentless rushing water.

Persevering from one cataract to the next the carp make it to the summit’s last falls.

Regrouping her energies in a pocket of scouring effervescence
every essence of strength, courage, and spirit is consumed in the launching over the fall’s summit.

And the dragon’s gate accepts her efforts a transforming gate of fire Revealing the birth of a new Dragon

born of the seed of desire planted in the heart of a small carp that once hid in the shallows.”

– Howard Schroeder, Threshold of the Dragon’s Gate

legend of carp turning into a dragon

A long time ago, in the distant past, the water of the
blue river that flowed from the sky, and the golden river
that flowed from the land were separated by the legendary
Dragon’s Gate.

The golden river, so-called because of the golden colour
of its water, was the last place where the inhabitants of
the sea could swim freely, after the gods that walked on
the earth had destroyed their massive home, believing
themselves to be the owners of everything they laid their
eyes on.

Amongst all the inhabitants of their water, the Koi family were the
most beautiful of all, gleaming in the sunlight like brilliant stars.

The black one was father Koi, the red one was mother Koi, and their little son was a remarkable deep blue colour.

What the little Koi fish wanted more than anything was to reach the
waters of the blue river after hearing from his father how there was
a time where there were no barriers between one place and the other.

The bravest fish, the dragon fish, flew across the sky like pearls lighting up the darkness.

The entrance was upstream, through the Dragon’s Gate to the Great Waterfall of the blue river. Every fish that got that far sprouted golden wings and so became a dragon fish. learn more here

koi dragon dragon story

The Story of the Koi Dragon

The legend says that a certain koi had the strength and courage to climb a certain waterfall.

When the koi reached the top exhausted, yet having reached its goal, the koi was transformed into a dragon.

The koi dragon is one of the mythical characters in the Japanese culture which is not actually a dragon.

It is a Japanese fish (Koi fish), which has the power to turn into a dragon.

The koi dragon starts to swim off as a fish up a river and then when it reaches a certain waterfall, tries to cross it.

If it is able to cross the waterfall, then it transforms itself into a dragon and thus it is known as the koi dragon.

The tattoo stands for overcoming obstacles through courage and perseverance.

As the koi fish swims up the waterfall and transforms itself to a
dragon, it symbolizes that nothing is impossible when you believe.

If you work hard and put yourself to tests, you will eventually rise
above your fears and become the ruler of your destiny.

The Daffodils (which are a year old) represents my sisters and their
unconditional and unselfish support and encouragement they provide through each journey.

I love this tattoo as it is something I feel everyone can relate to
throughout their own journey through life. read more here

legend of the dragon gate

LEAPING THE DRAGON GATE

koi fish turning into dragon

On the Yellow River at Hunan is a waterfall called the Dragon Gate. It is said that if certain carp called Yulong can climb the cataract
they will transform into dragons.

Every year in the third month of spring they swim up from the sea
and gather in vast numbers in the pool at the foot of the falls.

It used to be said that only seventy one could make the climb in any year. When the first succeeded, then the rains would begin to fall.

This Dragon Gate was said to have been created after the Flood by
the god-emperor Yu who split a mountain blocking the path of the Yellow River.

It was so famous that throughout China there was a common
saying that: ‘a student facing his examinations is like a carp attempting to leap the Dragon Gate.’

Hunan is not the only place where this happens. Many other waterfalls in China also have the name Dragon Gate and much the same is said about them.

Other famous Dragon Gates are on the Wei River where it passes
through the Lung Sheu Mountains and at Tsin in Shanxi Province. learn more here

koi care Ways to Encourage Your Kids to Take Care of Their Koi

koi care Ways to Encourage Your Kids to Take Care of Their Koi

Giving a child a goldfish can be an excellent way to teach responsibility. Once your children are a bit more mature, you can introduce them to koi fish.

Although koi require more care than goldfish, they are also more
versatile, and they can be placed indoors or outdoors.

Use latch hook hairstyles or another extra special treat to reward your child for a job well done.

You will be happy to learn that your kids are capable of caring for
your koi fish once you teach them how to do things correctly.

Here is the best way to get kids to care for their koi.

Ask Your Kids to Demonstrate
Setting up and maintaining a koi pond can be fun, so your children will want to get hands on right away.

After the koi are safely placed in their aquarium or pond, you can have your kids show you that they know what to do.

Have them feed the koi while you stand back and observe. When it comes time to clean out the pond or tank, give your children the tools and supervise them as they set out to work.

As long as the responsibilities you give them are age appropriate,
your children will impress you with how well they take charge.

Make Them Responsible for a Set Period of Time

When kids are old enough to be home alone for a period of time, they’re definitely big enough to take care of their own koi.

Add koi care responsibilities on your children’s chore chart so they know what to do.

This can mean that they need to check the koi pond’s water
temperature every morning, or that they will need to feed their koi every day after school.

Give them some responsibility but check up on them so that their koi are guaranteed to stay healthy.

After a while, you can trust your kids to be responsible and you can
even consider rewarding them with a funky hairstyle, like a mohawk or crochet braids.

Quiz Them on Their Koi Knowledge

After you have seen your kids feed their koi, clean out the tank, and
check on their fish, you need to do just one more thing to ensure that they are fully responsible.

Quiz your children on their knowledge of koi to see if they’ve got all the facts down right.

Ask them about what water temperatures are safe for koi, how
much food they should feed their fish, and what they should do if they see their koi are sick.

Some of their answers might surprise you, but overall you can expect them to get the majority correct.

Koi fish live for a long time if they are cared for well, so your kids
can grow up with a family pet that sticks around for decades.

Get them started early so that they can care for their koi fish, even when you aren’t at home.

As their fish grow larger and their collection becomes even more
vast, they will get to know their koi on a personal level.

Can you keep koi fish in a tank?

Keep koi in large aquariums for a few months at a time. If you live in an apartments, you may have to keep koi in aquariums for their entire life.

That is possible, as long as you do not overcrowd the aquarium with too many koi. … Your tank should have 1 cubic foot per 1 inch of koi fish length.

How long can koi fish go without food?

Many experienced fishkeepers routinely leave their charges for two
to three days without making any provisions for feeding.

Almost any fish can go that long without fish food (more about that later, as well). However, if you’re going away for longer, some preparation may be needed.

building a koi pond How to Create an Eco Environment for Your Koi Fish

building a koi pond


Koi fish can be a beautiful, colorful addition to a garden, which is
why many homeowners choose to incorporate them into their ponds.

If you are considering adding koi into your landscape, find out how
to create an eco-environment for your koi fish.

Introduce a Circulation System

A circulation system is simply the pumps and plumbing, which are
required to provide the appropriate oxygen levels to effectively care
for both the koi fish and plants.

It will also help you to maintain your pond’s aesthetic appeal, as it will create a cleaner environment.

Install an Effective Filtration System

A filtration system should include both a biological and a mechanical filter.

The biological filter will provide a surface area for the colonization
of bacteria, so that it can remove the water’s excess nutrients.

While the mechanical filter will not only feature the pond pump,
but it will prefilter the water and remove debris along the water’s
surface, and can, therefore, prevent the development of organic
materials on the pond’s floor. By doing so, it will create a healthier environment for all organisms within the pond.

Utilize Solar Power for Your Pond

Reduce your pond’s energy consumption and your household bills
by opting for solar power pumps and filters.

The systems will be powered by natural sunlight, so it won’t cost you a penny to run a clean and healthy pond for your fish.

If you are looking for high-quality, affordable circulation and
filtration systems, visit Water-garden.co.uk.

Add Fish for Natural Maintenance

Many people might believe that fish will create a maintenance
problem in a pond, but they can actually do the opposite.

Fish can actually reduce maintenance in a pond, as they are known
to graze on the string algae and bottom feed along the pond’s floor.

So, if you want to add a pond to your garden, you should ensure it’s bursting with life by adding plenty of fish.

Embark with Seasonal Maintenance

Of course, a pond will need a little bit of maintenance to create a
healthier environment for both your koi fish and the planet.

For example, seasonal maintenance will require you to drain your pond completely.

You will also need to scrub your substrate and rockwork with a
pond scraper, or you could use another algae removal device.

Routine Maintenance

Routine maintenance can be a lot less laborious than seasonal maintenance.

It simply ensures the effective functioning of your filtration system,
and you’ll need to rinse both the biological and mechanical filter. You’ll also need to remove the pump for cleaning.

For example, you should remove each moving parts for cleaning,
and you should lubricate all gaskets.

As ponds are susceptible to limescale build-up, this can cause a
pump to stall or burn out, which can create unhealthy pond.

You must invest in a high-quality pond pump descaler, which
should be free from harmful acetic acid and chlorine additives. Also, don’t forget to check its pipes and tubing for cracks, leaks, and weak spots.

How much does it cost to build a koi pond?

A shallow 4′ x 6′ or 6′ x 8′ professionally-installed pond, including
excavation, liner, filtration system, and simple rock border might cost $2,000 to $3,500. As a DIY project, the same pond might cost $500 to $1,000. Larger ponds, depending on features and equipment, can easily cost $5,000 to $15,000 or more.

What is the minimum size for a koi pond?

A pond for goldfish or water lilies need be only about 2 feet deep for zones 5 or greater.

Ponds built in colder areas may need more depth to keep the pond from freezing solid.

Ponds built for koi should be close to three feet or deeper to allow these larger fish enough space.

How much space does a koi fish need?

Koi should be stocked based on a reasonable estimate of their full growth, not on their size at purchase.

Most well-maintained ponds will support 1″ of fish per ten gallons of water.

Though some koi in the largest ponds will grow to 36″, we recommend using an average of 21″.

What you need to consider when designing a pond

What you need to consider when designing a pond

So, you’ve decided you want a koi pond in your backyard. Congratulations, it’s a great decision. Ponds aren’t just for keeping fish such as koi in, but they can also encourage other nature into your garden, provide a stunning focal point for visitors to admire and offer a source of relaxation – who doesn’t love closing their eyes and hearing nothing but the sound of trickling water as your very own pond babbles away not far from your back door?

With the decision taken to construct a pond, the big question is, what is your pond going to look like and where in your backyard is it going to go? Here are the factors you need to consider when designing a pond.

Decide on the style of your pond

When her home in West Village, New York needed a refresh, actress Julianne Moore hired professional landscaper Brian Sawyer to redesign her garden. Thankfully, you don’t need to source a professional with a Guaranteed Scholarships in Garden Design to help you decide on the style of your pond. When it comes to a pond housing fish, the most common designs are a formal shape, raised up and near to the house so that you can see your fish swimming around in all their splendor.

Consider the safety aspects

Arguably the most important factor to consider when it comes to designing a pond is the safety aspect. We’ve all read horror stories about young children accidentally walking or falling into ponds with terrible consequences. A raised pond can prevent that happening by providing a physical barrier between child and water. It also offers an edge to sit on, which can be handy if you want to relax in the garden or if the pond is for somebody elderly who may need to sit down while working on the pond. If you are still worried about the potential of a child falling in, then you can purchase a pond cover or netting. This will also protect your fish from any urban animals that may see them as an easy lunch.

Think about the electricity supply

Most likely, your pond is going to require a filter and pump while many of us will also want to install fountains or waterfalls. All of these require electricity to work. That can have a bearing on the positioning of your koi pond, as you are going to need it to be relatively close to a mains supply, which will probably come from a building. You should always use and consult a qualified electrician, especially when dealing with electricity and water.

Check the positioning of underground services

Your pond is going to require at least some digging down, so you need to check that it isn’t going to be situated above any water pipes, sewage pipes of electric cables. The last thing you want when you start constructing it is to cut through any of those three utilities.

Avoid siting your pond in the shade

There are several reasons for avoiding putting your koi pond in the shade. The most obvious is that if it is situated under trees, then come fall it’s going to fill up with fallen leaves which will be a nightmare to remove. If you want flowers to bloom among the water, then you’ll need to choose a position which receives sunlight for around six hours a day.

Choosing the koi fish – this can help teach children responsibility by allowing them to choose which koi fish to buy, what to call them,

and taking charge of their food regime etc.… so it is a great introduction to looking after pets, without too much hassle.

Add a water feature for movement – while sitting by a pond is relaxing in itself, studies have shown that listening to

the sound of falling water has incredible therapeutic and soothing properties so once you have your pond in place, try adding a small water feature.

Some believe, however, that long ago, they descended from dragons.

The story goes that once there was a huge school of fish made up of thousands of Koi swimming in the Yellow River in China. They went upriver, pushing against the current until they came to a waterfall. Many turned back, believing it was too difficult an obstacle.

Some koi, however, kept trying and trying to jump over it. They kept at it for hundreds of years until finally, one koi made it to the top. To reward his persistence and bravery, the gods of the river turned that fish into a golden dragon.

Today the waterfall is known as the dragon’s gate, and some believe that any fish that can jump it will still be transformed into a dragon.
