You’ve followed all of the right steps, and yet your Koi won’t breed. Don’t let another season pass without a success spawn.
Perhaps you should examine some of the common problems with
Koi and determine if the solution might be altering something
other than your breeding techniques.
The three most common areas of Koi problems are the following:
problems with Koi setup, water quality issues, and problems with the Koi themselves. Let’s examine these areas of interest one by one.
1 Problems With Your Koi Setup
a. Water Volume – This is the most typical Koi pond issue. If your
water volume is off, all of your calculations for your treatments and
heating requirements will be ineffective and create a sub-optimal environment for breeding.
While it should be relatively easy to ensure that you don’t have too
much water in the pond, a common mistake (particularly among
inexperienced Koi breeders) is too little water.
Why? It is easy to forget to compensate for natural loss of water
through evaporation and absorption. Check your water levels frequently and always before adding a treatment to the pond.
b. Incorrect Volume Calculation – Secondary to the needing a
volume correction, improperly calculating your water volume will also cause problems.
Some pond shapes, particularly homemade natural varieties, are
not easy to measure for volume accurately.
Furthermore, even if you know your pond volume from its
vendor, you may have failed to accommodate for displacement from your decorations.
Do yourself a favor and purchase a water meter for filling your pond. It is the safest and most accurate way to determine your true water volume.
c. Pump Malfunction – All pumps, even the most expensive brands, will wear out in time.
Remember that rarely will you encounter a case of a perfectly
functioning pump failing completely in a short amount of time.
Wear and tear will cause a gradual decline in efficiency.
You can increase the lifespan of your pump by conducting regular
cleaning and maintenance. Check for proper function frequently, and always keep a backup in case of sudden failure.
2. Water Quality Issues
a. Evaluate your water sources. If you are using tap water and your
Koi are not breeding, you may need to consider the possibility that
the tap water in your area is unacceptable for your pond.
In general, it is not recommended to use unfiltered tap water for Koi ponds anyhow.
While you can purchase purified water from the store, this will
become expensive in a short amount of time.
Consider installing a purifier for your house or at least the faucet where you draw the water for your pond.
b. If you think you may have water quality issues, you should probably get a salt meter. Without accurate measuring equipment,
knowing what your levels truly are is guesswork, at best. This can make hard, if not impossible to isolate your problems.
3. Unhealthy Koi
a. Inspect your Koi frequently. Look for damages to the scales, abnormal behavior, or anything else unusual.
Physical stress on your Koi will greatly reduce their likelihood of breeding.
Abnormal behavior in fish is the first sign of toxicity or sickness. Motor function of your fish will be easily affected by factors like pH or salt content of the water.
If your water is not cleaned or poorly maintained, you may
encounter disease, which can spread quite rapidly if untreated.
b. Not all health problems are easily identified. If you’re not handy
with a microscope or don’t have one, perhaps you should consider investing in one and a guide on how to use it.
Conducting periodic scrapes on your Koi and inspecting scales
under the scope is a good way to preemptively identify koi diseases and
parasites before they become an unmanageable problem.
c. If all else fails, seek veterinary advice. No one will argue that
your Koi flock is a considerable investment, particularly if you are
trying to breed for profit.
Even though professional consultation can be expensive, the cost
may pale in comparison to the cost of losing some or all of your flock to a disease. Remember to consider the cost of supplies and all of your valuable time spent raising your Koi.
Why are my koi staying at the bottom of the pond?
Many people stock their yard ponds with goldfish or colorful koi. Both are species of carp.
If you live in the north and the surface water is cold from extreme weather, they will head for the bottom to keep warm.
But the major reason fish stay on the bottom of a pond is that is where the oxygen is.
How do you know if a koi fish is dying?
Signs of Koi Disease
Fish segregating itself from others.
Fins clamped close to body.
Fish acting listless or lethargic.
Gasping at surface of pond.
Fish Sitting on bottom.
Hanging near surface or near waterfall.
Red streaks in fins.
Why are my koi fish dying?
Water Quality. This is THE leading cause of the death of Koi fish. It largely stems from the fish’s waste products and the first iteration of that is ammonia. … In the biological cycle of a koi pond ammonia is produced from fish waste, which gets turned into nitrites, then nitrates.
Why is my koi fish floating?
A sinking koi pellet may be helpful if the issue is caused by gulping air while feeding. Poor nutrition or nitrate-rich koi food may be the cause of a bladder infection or even stress causing the fish to swim strangely.
Can a fish recover from swim bladder disease?
When it is suspected the fish has swim bladder disorder due to a fall or injury, time is the only treatment. Keep the water clean and between 78 and 80 degrees Fahrenheit and add a small amount of aquarium salt to the tank. If the fish does not recover and is unable to eat, the humane resolution may be euthanasia.
Why do koi fish swim on their sides?
Although intestinal parasites and microorganisms can cause swim bladder disease, it mainly stems from overeating, eating too quickly or gulping too much air during feeding time.
Enough pressure on the swim bladder will cause the fish to swim any which way but up
