What causes koi not to eat?

Koi fish friends have mostly encountered the phenomenon of koi do not eat, at this time, many people began to busy overwhelmed, fish this is what happened? Inexplicable hunger, so began to be sick and desperate to seek medical help ......

Would a koi carp shut up and not eat for no reason? Never!

When you don't know why your koi won't eat, don't say it's inexplicable, only that you're not taking good care of it!

Counting back two weeks from the day you found out your koi was on a hunger strike, you carefully recall every detail and allow your brain circuits to fully explore every move that has a connection to it, and you realize that you must have done something that violates the normal physiology of koi.

If you familiarize yourself with the personality of your Koi, you will notice many unusual things in the water quality or predators. When you learn to recognize the behavioral cues of your Koi, you gain valuable information such as environmental changes and reminders of the Koi's physiological state. This allows you to respond to their needs, which in turn increases their happiness while developing a wonderful pet owner relationship.

In fact, there are major categories of common koi hunger strikes:

One category is intestinal disorders in koi caused by fluctuations in water quality, which usually occurs in new fish;
The other type of intestinal lesions in koi caused by enteritis are commonly found in older fish.
Whichever it is, we need to avoid indiscriminate medication with our eyes closed. It is better to find the cause of the disease first and then look for countermeasures.

1


Water quality fluctuations

There are two reasons for fluctuating water quality:

1, the novice does not know how to keep water, when the new fish into the pool, koi produced feces into toxins, resulting in koi produced a mild "ammonia nitrogen poisoning", and then the fish went on a hunger strike;

2. Violation of over-watering (constant temperature and acid-base transition to avoid differences in water temperature and pH when new fish come home).

The vast majority of encounters with koi not eating are caused by these two reasons. There is, of course, a third specific trigger for extinction, which will not be discussed in detail as it is outside the scope of today's discussion.

Intestinal lesions due to enteritis

How can I prevent and treat a koi hunger strike triggered by enteritis?

One of these is bacterial enteritis, usually induced by unclean fish food.

Because there are differences in the constitution of different koi, in this case, usually only some of the koi go on a hunger strike, not all of the koi in the full pond.

This, then, becomes the way to differentiate between the two common hunger strike situations.

The best way to prevent bacterial enteritis-induced hunger strikes is to avoid live food, which I have seen in too many cases.

In addition, there are also the following reasons for koi hunger strike in daily keeping, which are rare but should be noted:


I. Parasites

When the body of the fish parasites, the fish will be physically ill, gills more parasitic wheelworms, oblique tube worms or fingerling worms after the gills increased mucus, the ability to use oxygen is reduced, resulting in a decline in food intake.


Second, the water body dissolved oxygen is too low
When there is a large number of rotifers or branchiopods in the water or when there are consecutive cloudy and rainy days, etc., all of them can reduce the dissolved oxygen in the water and cause a decrease in the appetite of the fish.

III. Bacterial infections

When a fish is suffering from enteritis, rotting gills, or other bacterial diseases, it can cause non-feeding.


IV. Harmful Algae
Especially some indigestible algae such as nudibranchs and cyanobacteria, which cannot be digested in time after being ingested to the extent that it affects the feeding of the fish. Meanwhile, some algae contain toxins such as Microcystis aeruginosa, which will stimulate the intestinal tract of the fish and make the intestinal tract red, causing enteritis and even poisoning.

V. Caused by material change
If the same feed is used for a long time, the sudden change of feed will cause discomfort and stress to the fish, resulting in a decrease in food intake or even refusal to eat.


VI. Due to the use of drugs

In the process of breeding to often use some drugs to control pests and diseases, and some drugs in the insecticidal at the same time will also affect the fish's nervous system, affecting the feeding.

VII. Excessive content of harmful substances
If the content of ammonia nitrogen, nitrite and other harmful substances in the water is too high for a long time, it will cause damage to the gills of the fish, affecting the respiration of the fish, causing the fish to produce pathologic hypoxia, leading to a decline in feeding.

Eight, caused by too large a temperature difference

The temperature difference between day and night is too large, with high temperatures during the day and higher water temperatures. And at night, the temperature plummets, causing the water temperature in the surface layer to drop sharply and the density of the water to increase. And the bottom layer of water is warmer and less dense, so it causes convection between the upper and lower water layers.

The bottom layer of anaerobic water carrying a large number of residual bait, feces and other organic matter to the bottom of the pool to the upper level of the flow, the water becomes turbid, and at the same time, the decomposition of organic matter oxygen depletion, so that the entire water body is in a state of hypoxia, thereby affecting the fish feeding.

At this time, we will find that the fish are usually not good at feeding in the morning, and good at feeding in the afternoon. The main reason is that the morning, especially in the morning the dissolved oxygen in the water is very low, the fish ingestion is not good, and after a noon sunshine, the dissolved oxygen in the water due to algae photosynthesis and rise, the fish began to ingest, and at this time, the fish friends feed eagerly, eager to make up for the morning did not eat the feed back, so more than the usual amount of feeding.

Koi respond better to gentle shifts and can be shocked when they experience rapid changes - whether it's the environment, the temperature,Food, or anything around them, really! Always give your koi time to adapt to new changes to avoid shock. This is a key factor in mood changes, plus creating a comfortable, healthy ecological environment for them is what will allow them to adapt to surviving in your pool, and subsequently provide you with the ornamental value you want!


To keep koi well, it is important to establish a well-establishedFiltration system is the key.
