CATDOLL : CATDOLL: Can parrot fish with gill rot still grow? What is the specific medicine for fish with gill rot?

1. Can the gills of parrot fish still grow if their gills are rotten?

The tail (fin) of a parrot fish can grow back if it rots. But the gills are more difficult to deal with, because if the gills rot, it will cause the parrot fish to die quickly.

When the gill cover of a parrot fish turns upside down, it is more troublesome to deal with. It can be treated surgically by cutting off the turned-out gill cover together with the gill membrane. Young fish can also undergo surgery. However, the turned-out gill cover of a parrot fish will continue to recur and requires continuous treatment and prevention.

2. What specific medicine can be used to treat fish gill rot?

My goldfish had gill rot, so I searched online for special medicine. Because the treatment time is really limited, I had to hurry up. Then I saw Deke's big white tablets, and after reading the reviews, I found that they were all good, so I immediately placed an order. Fortunately, the logistics was also fast. After it arrived, I used the medicine for three consecutive days, and the goldfish showed improvement. The water in the tank no longer had a fishy smell. It really saved my fish's life in time. Now their fish medicine has become a regular part of my fish farming.

3. What causes koi gill rot?

1.

Temperature difference: When Koi fish change water, the temperature difference between the new and old water is 2 degrees or more, which often causes discomfort to the fish and leads to illness. Especially in spring, autumn, and winter, special attention should be paid when changing water.

2.

Changes in water quality: Koi water deteriorates due to excessive feeding and fermentation of residual feed. If the water is not changed in time, Koi will become sick. In addition, Koi may become unwell or die of poisoning after being put into tap water because the newly released tap water is not aired out enough. Or too much dechlorination agent baking soda is added to the tap water, causing the water to become cloudy. If not carefully observed, Koi may die. This is especially common in hot weather.

3.

Changes in water and soil: After long-distance transportation, koi arrive in a new environment. Due to the differences in climate and water quality, if they are not properly managed, they may become sick.

4.

Mechanical damage: Carelessness or improper operation during daily catching or transportation of koi can cause the koi scales to fall off or the organs to be damaged. If not observed in time, it can easily induce the koi to become sick.

4. How to treat fish gill disease?

1. For bacterial gill disease, we should mainly use external sterilization and improve the water body to eliminate pathogens in the water, clean the water body to reduce pathogens and enhance the disease resistance of fish. For external drugs, use bactericides, use bleaching powder (containing more than 30% chlorine) 1-1.5 g/m3, or strong chlorine 0.3-0.5 g/m3 and other chlorine-containing agents or sterilizing drugs (such as benzalkonium bromide, chlorine dioxide, etc.) to spray the whole pond. Depending on the severity of the disease, you can apply the medicine 2-3 times continuously. For internal drugs, you can feed traditional Chinese medicine formulas or chemical drugs for clearing heat and detoxification, etc., and choose one of them to make medicine bait, and feed it continuously for 3-5 days to restore and enhance the disease resistance of fish. 2. If the disease is caused by common parasitic diseases such as Cryptochaete spp., Trichodina, Hemiptera, Trichodina, Glossocypterus, Dactylorhiza, Trichodina, and Chinese Tripterygium, you can use trichlorfon, cypermethrin, copper sulfate, etc. and insecticides sold in the market to spray the whole pond, and you can apply the medicine continuously for 2-3 times. When using copper sulfate treatment, you can also use a mixture of copper sulfate and ferrous sulfate (5:2) 0.7-1ppm (0.7-1.0 g/m3) to spray the whole pond.

5. What does labyrinth fish mean?

Labyrinth fish are a type of fish that live in the deep sea. Because labyrinth fish mainly live in deep sea waters, it is difficult for ordinary people to come into contact with them, so many people know little about them. Labyrinth fish are a type of vertebrate. They have special gills and head structures that can complete activities such as hunting underwater. Due to the limitations of their living environment, the number of labyrinth fish is relatively small, but they also play an important role in the marine ecosystem. Labyrinth fish include multiple genera and species, such as Labyrinthus and Scallopbryx. They have different appearances, some are like needles, and some are more like arrows. With the improvement of awareness of marine protection, people are paying more and more attention to the protection of labyrinth fish. Strengthening the protection of deep-sea ecosystems is of great significance to maintaining the ecological balance of the earth.

6. How to treat gill rot?

1. Symptoms of gill rot in grass carp. The body and head of the diseased fish are black, the inner surface of the gill cover is congested, the middle part is often eroded or has a small round transparent window, the gill filaments are swollen or congested and black, the mucus increases, and the ends are incomplete.

2. Grass carp carriers are the main source of gill rot. The bottom mud and water sources that have been contaminated by fish with gill rot are also the source of gill rot. The more pathogens there are in the water, the worse the water quality, the worse the bottom quality, and the greater the fish density, the easier it is for the disease to break out and spread.

3. Use symptomatic medication. For gill rot caused by myxobacteria, use 20-30 kg of quicklime or 1 kg of bleaching powder per mu and spray it throughout the pond. For gill rot caused by protozoa, use 1.5 kg of copper sulfate and 0.5 kg of ferrous sulfate per mu and mix them and spray them throughout the pond. For gill rot caused by Chinese mullet, add crystal dichlorvos to water and spray it throughout the pond, which has a good effect.

7. How to deal with rotten gills of mandarin fish?

Caused by parasites (wheelworms, worms, tubeworms, etc.)

In the early stage of our breeding, the probability of parasites occurring in mandarin fish is very high. The general conditions for occurrence of parasites are foreign bait fish, poor bottom quality, lack of oxygen, large temperature difference, etc., which are prone to parasitic diseases.

, duration 00:25

Caused by water quality problems (ammonia nitrogen, nitrite, pH)

The main problems are serious pond loading (high density of bait fish), deteriorating water quality, insufficient dissolved oxygen, especially high levels of nitrite or ammonia nitrogen.

Gill rot caused by bacteria and branchial fungi

We have different solutions for gill rot caused by different reasons. For the above problems, friends who raise mandarin fish must distinguish which situation causes gill rot. Incorrect judgment may cause us to use too much medicine, which will directly affect the treatment effect of mandarin fish and increase the burden on the liver of mandarin fish in the later stage.

Suggested treatment for gill rot in mandarin fish:

1) Gill rot caused by protozoa and worms:

The first day is to deal with parasites. Choose legal products that you trust. For example: 1 pack of protozoan cream + 2 packs of fiber killer = 2 acres of water. Use it twice in serious cases.

Use sterilization products on the second day: such as hydrogen peroxide granules, concentrated glutaraldehyde solution, etc.

2. Water quality causes gill rot:

We treat the water quality first (ammonia, nitrite, pH) and then deal with the gill rot.

3. Bacterial (after excluding parasites and water quality) direct disinfection

Day 1: Take corresponding measures according to gill rot: if it is caused by parasites, treat the parasites first; if it is caused by water quality, adjust the water first; if it is caused by bacteria, disinfect first;

2nd and 3rd morning: methionine iodine (povidone iodine solution) solution + sprinkle ginger. 5th afternoon: Hydrogen peroxide granules, use for 2 consecutive days.

8. Briefly describe the characteristics of gill-lung ventilation in fish?

The respiratory organs of fish are gills. The gills are structures specially adapted for breathing in water. Each gill is composed of gill lamellae and gill filaments. When breathing, the gill lamellae and gill filaments are fully opened, which will increase the contact area between the gills and the water and increase the chance of combining with dissolved oxygen in the water. When fish are in water, they open and close their mouths to breathe; when they open their mouths, they inhale water and close their gill covers; when they close their mouths, the gill covers open to let water flow out. When water flows through the gills, the dissolved oxygen in the water is absorbed by the microvessels on the gills, and carbon dioxide is discharged into the water at the same time.

Fish have a single circulatory system, and their heart has only one atrium and one ventricle, and the heart is full of deoxygenated blood. The heart sends the deoxygenated blood to the gills for gas exchange, turning it into oxygenated blood, which is then sent to various parts of the body and then flows back to the heart as deoxygenated blood.

Among all vertebrates, only fish have this type of respiratory and circulatory system from beginning to end. Because fish breathe in water, the oxygen content in water is much less than that in air, so their respiratory and circulatory systems are adapted to life in water, which is determined by their living environment.

9. What is the difference between bacterial gill rot and parasitic gill rot?

Bacterial gill rot and parasitic gill rot are two different diseases with significant differences in causes, symptoms, and treatments.

Bacterial gill rot is a disease of fish gills caused by bacterial infection. Common pathogens include Penicillium, Vibrio, Aeromonas hydrophila, etc. Its characteristics and differences are as follows:

1. Cause: Bacterial gill rot is caused by bacterial infection on the gills. It is often caused by poor water quality, lack of oxygen, over-predation, irritating substances, etc., which lead to the fish's reduced resistance and susceptibility to infection.

2. Symptoms: The gills of fish suffering from bacterial gill rot will show discoloration, swelling, ulceration, peeling and other symptoms. The gills may have mucus or pus secretions. The fish may also have symptoms such as shortness of breath and loss of appetite.

3. Detection and treatment: Diagnosis of bacterial gill rot is often done by examining the gills of the affected fish to find the pathogen, and then doing bacterial culture and drug sensitivity tests. Treatment usually uses appropriate antibiotics, while improving the living environment of the fish and enhancing its immunity.

Parasitic gill rot is a gill disease caused by gill parasites. Common pathogens include trematodes, flagellates, and endoparasitic nematodes. Its characteristics and differences are as follows:

1. Cause: Parasitic gill rot is caused by parasitic infection of the gills, which is often caused by polluted water sources and fish inhaling parasite eggs or larvae when in contact with infected fish, leading to parasitic infection.

2. Symptoms: The gills of fish with parasitic gill rot often show redness, swelling, rolling, and vasodilation, and sometimes parasite eggs or larvae can be seen. Fish may also experience symptoms such as rapid breathing, reduced activity, and loss of appetite.

3. Detection and treatment: Parasitic gill rot is often diagnosed by examining the gills of the affected fish and observing the morphological characteristics of the parasites. Treatment is usually through drug treatment, choosing appropriate antiparasitic drugs for a course of treatment.

There are significant differences in causes, symptoms and treatments between bacterial gill rot and parasitic gill rot, so it is important to accurately distinguish the difference between the two when diagnosing and treating them. If your fish show unusual symptoms, it is recommended that you consult a medical professional or veterinarian for diagnosis and treatment.

10. How to treat koi gill rot?

No matter you raise koi in a koi tank or a fish pond, and no matter how many varieties of koi you raise, if you are not careful your beloved koi will suffer from koi disease. Among them, the disease of koi gill rot is a common koi disease in the koi breeding process, which is called koi gill rot disease.

In fact, the rotten gills of koi are caused by columnar fibrotrophic bacteria and poor water quality. In the season when the disease is prevalent, sick fish continue to spread pathogens in the water, and healthy fish come into contact with pathogens, especially when the gills are damaged, which is particularly prone to infection. In addition, if the stocking density is too high and the water quality is poor during the koi breeding process, koi gill rot is also the most likely to occur.

The symptoms of Koi gill rot disease are that the epidermis of the gill cover bone of Koi fish is congested, and sometimes corroded into a round transparent area, also known as "open skylight". Sometimes the tip tissue of the gill filaments rots, causing the gill filaments to be incomplete. In addition, the rotten gills of Koi fish cause the gill filaments to break, which causes the diseased fish to have difficulty breathing and float on the water surface. Other symptoms of this disease are loss of appetite, slow reaction, and weight loss. At this time, we must treat it in time, otherwise it will bring serious consequences.

For the problem of koi's gills being rotten, we need to provide timely treatment to prevent your beloved koi's condition from worsening and leading to death. The treatment method is:

① Observe the koi carefully. If it is confirmed that the koi has gill rot, the first thing to do is to stop feeding, start the filtration circulation equipment in time, and sprinkle formalin in the water to make the water concentration reach 15 mg/L. After 12 hours, sprinkle furazolidone to make the water concentration reach 10 mg/L. You can also sprinkle 0.3 mg/L of malachite green in the aquarium. Carry out treatment continuously for 4 to 5 days and the fish will recover.

②You can also use potassium permanganate to treat Koi gill rot. The method is to clean the filter and add a little salt to the fish tank (pond), and stop feeding for a few days. Potassium permanganate can be used in the original tank (pond) for treatment, with a concentration of 0.2ppm, and the fish body can be soaked for several days until the condition improves.

In fact, it is possible to prevent koi gill rot in advance. The preventive measures are: 1. During the koi breeding process, we must pay special attention to the management of water quality, feed in moderation, and do not let the koi eat too much; 2. Change the water frequently to avoid water pollution; 3. If possible, install oxygenation equipment in the fish tank or pond to ensure the dissolved oxygen content in the water. Knowing how to prevent koi gill rot, you will also know how to raise koi fish, so that your koi can live healthier.
