Why do fish have white eyes???

The changes in the eyes of a fish after death are due to a variety of factors. First, the fish's eyes may lose pigment because the eye is unable to continue to provide liquid melanin after death. In addition, the white belly of the fish may float on the surface of the water after death, because the swim bladder loses its normal physiological functions, and because the hollow structure of the swim bladder brings greater buoyancy, the density of the fish's belly is relatively smaller and lighter, so the white belly will float on the surface of the water, forming a whitening.

However, it is important to note that not all fish will have white eyes after death, as this change may be affected by factors such as the specific cause of death, the species of fish, environmental conditions, etc. In conclusion, the eye changes after death of fish are a natural phenomenon that is caused by changes in the physiology of the body after death.

The fish's eyes become cloudy two hours after they die. The eyes of the newly dead fish are transparent and the eyes are also very clear, and after about 2 hours, they will become hard, and the eyes will be a little cloudy, and they will still be hard after about 10 hours, and the fish will be wrapped in a layer of white and slippery liquid.

Fishes are ectothermic aquatic vertebrates that swim and feed on the upper and lower jaws by breathing with their gills, swinging through the tail and trunk, and the coordination of their fins, and belong to the vertebrate subphylum of the phylum Chordates.

Introduction to fish. There are about 32,000 species of fish found in the world, and the fish live in the water, distributed in the ocean and freshwater, with two-thirds of the fish living in the ocean and the rest living in freshwater. There are 2,500 species in China.

Fish are mostly cold-blooded, and a few are warm-blooded, breathing with gills and having jaws and fins. Living fish can be divided into two main groups: cartilaginous fishes such as sharks and bony fishes such as linear and wavy fins. Both groups of fish first emerged from the Early Devonian.

The whitening of the eyes of fish is blindfolded, and blindfolds are mostly due to bacterial infections. Medium and large fish like to fight, and if they are not careful, their eyes will be injured, and they will be blindfolded if they are infected with bacteria after being injured; When the environment of the fish tank is too small, the fish may be blindfolded; During delivery and transportation, it is easy to fall and hurt the fish and be blindfolded; Poor control of the frequency or amount of water exchange, and large temperature difference will cause fish to be blindfolded.

If it's a goldfish, it may be because the transparent membrane on the outside of the eye has broken! Compare it to the other eye! If that's the case, it shouldn't be anything!

There is no picture and no truth, and it is suspected that it is blindfolded, and it will not be cured.

It is mostly due to poor water quality, including many harmful substances in the water, such as ammonia, nitrite, oil, bacteria, parasites, etc., and it may also be caused by too much change in water temperature.

There are two main reasons why the fish dies and turns white:

1.After the fish dies, the blood vessels and internal organs in the body are prone to decay, and the decaying bacteria will form a substance called "mold", which will attach to the fish and make the body of the fish white.

2.In addition, after the death of the fish, the enzymes in the body will gradually lose their active lead, which will also promote the growth of mold and make the fish more likely to turn white.

These reasons can cause the fish to turn white after death.

The reason why the body turns white after the fish dies is because after the fish dies, the internal cells in the body have been quickly buried and some of the tissues that have been oxidized and oxidized have become white. It is the scales of the fish that have undergone an oxidation bending reaction.

Because after the fish dies, the internal cells in the body have died rapidly, and some of the tissues involved in oxidation turn white. It is the scales of the fish that undergo an oxidation reaction.

Why is the body white when the fish dies The best: The fish died and the body was blistered and turned white.

Yes but it is recommended not to eat, if it is a dead fish, this fish generally means that it has been dead for a long time, and the eyes of another live fish have turned white, see if it is the outer membrane of his eyeballs or the inside, the outer membrane indicates that the water quality of the water that raised him is not good, and the inside indicates that he is infected with a disease.

The appearance of cotton wool-like white film is called water mildew.

Prevention and control: 1. Use malachite green (available in the flower and bird market) to wash the fish and potatoes for 10 20 minutes.

2. Use a cotton swab dipped in red potion to rub the affected area of the diseased fish.

3. Bathe the sick fish with 1% food and laughing salt water for 10 to 20 minutes.

1. It may be the symptoms of fish blindfold caused by poor water quality and bacterial infection, at this time, there is a white film on the outside of the fish eyes, and the eyeballs are cloudy, which is the symptoms of fish blindfolding. The fish tank does not change the water often and the water quality is turbid, then there will be many bacteria and microorganisms in the water, some ornamental fish have higher requirements for water quality, and the fish may be infected by bacteria if the water quality is too poor, resulting in blindfold symptoms, at this time, there is a white film outside the fish eyes, and the eyeballs are cloudy. At this time, you can add an appropriate amount of potassium-based blue malachite green (choose one) medicine to the water tank to take a medicinal bath to help the fish**.

If the water quality is not improved in time, the fish may become blind.

2. It may be that the fish eyes are injured, such as the fish fry purchased online were injured during transportation or the fish in the same tank were injured due to the fish fighting, and the eyes will also be white. If the fish raised in the same tank are more complicated, then there will be a situation where the fish will fight, especially the medium and large fish are more fond of fighting, and the fish eyes will also appear whitish after being bruised. In addition, there are cases where fish fry purchased online have been injured during transportation, resulting in eye injuries and whitishness.

Usually, if the fish's eyes are white due to injury, just wait for it to recover on its own.

How to deal with the problem of white eyes in fish?

1.Learn the cause of whitish fish eyes.

Pale fish eyes can be caused by a variety of factors, common causes include water quality problems, malnutrition, disease infections, etc. If the white part of the fish's eyes appears more pronounced than usual, then there is probably something wrong. Therefore, we need to know more about the causes of white fish eyes in order to better solve this problem.

2.Improve water quality.

Water quality is one of the main factors affecting the health of fish eyes. If the water quality is not good, it can affect the health of the fish, including the health of the fish's eyes. Therefore, we need to take some steps to improve water quality.

Some water quality modifiers, such as activated carbon and nitrifying bacteria, can be used to reduce the number of harmful substances and bacteria in the water. In addition, it is important to maintain the age of the water and change the water quality frequently. This effectively reduces the amount of harmful substances and bacteria in the water, thus reducing the impact on the fish's eyes.

3.Provide adequate nutrition.

Fish eyes also need adequate nutrition to stay healthy. If the fish lacks the necessary nutrients in its food, the fish may have problems with its eyes. Therefore, we need to provide our fish with a varied and balanced diet to ensure that they are getting all the necessary nutrients.

It is possible to buy specialized feed at the pet store or make some healthy meals suitable for the fish.

4.Pay attention to health and hygiene.

In addition to water quality and nutrition, healthy lifestyle habits are also very important. We need to pay attention to the hygiene of the fish tank, change the water quality frequently, clean up the waste and debris in the fish tank, etc. In addition, we also need to avoid exposing the fish to harmful substances and bacteria, and some disinfectants can be used to clean the fish tank and fish supplies.

In the process of daily fish farming, it is necessary to pay attention to washing hands frequently to avoid bringing external pollution into the fish tank.

5.Seek professional help.

If the above methods still do not solve the problem of whitening of fish eyes or kamiyama eyes, then we need to seek the help of a professional veterinarian. They can help us get to the root of the problem and give more precise and effective solutions to ensure the health of the fish.

Epilogue. White fish eyes are a common problem, but we can solve this problem by improving water quality, providing adequate nutrition, paying attention to health hygiene, and seeking professional help. When we find that the fish's eyes are white, we should not panic, we should treat it rationally and take corresponding measures to protect the health of the fish.
