Parasite is common. Especially the gills and skin. Fish mucus to come out in large quantities, to try.
Off to get rid of parasites. May have noticed a wound on the body. The body color of the fish with parasites, the island may be pale or dark.
Abnormal swimming unbowed Many parasites are found in fish culture density. Examples of common parasites.
And fish.
1. Tick Bell (Trichodina sp.).
Tick a bell-shaped protozoa aspheric tiny hairs around (cilia) below the surface.
The fish-like body binding Kghakr (Figure 1) can reproduce quickly. Found in gills and skin by
Island fish with parasites, they will not eat it. Anxious to turn to swim, there have been important to the pit wall color.
The parasite is removed. Pale gums and erosion. Fish in large quantities can cause death due to hypoxia.
(Kiri 2545) should be 2-3 days before being released into the water, fish farming if the fish has a bell attached ticks should be destroyed immediately.
Since these parasites have increased dramatically. Most patients using 25-40 ml of formalin.
1,000 liters of water, soak for 24 hours.
2. Leech clear (monogenes).
Leech into a very small external parasites. Seen with the naked eye can not see. The body is clear (Figure 2).
Is an island in the teeth and gums and skin. The spread of these parasites throughout the years, especially in
Fish farming is intensive. Leech is a clear common type Gyrodactylus sp. And Dactyrogyrus sp. Fish with parasites.
These islands may be a darker color than normal. Eat less. If a series of islands in the gums, causing gum.
Inflammation of the fish and the exchange of air decreases. Result in fish kills as well. Maintained by the use of formalin 25-40.
Ml per 1,000 liters of water to soak up.
3. White spot disease.
Caused by protozoal Ichthyopthirius multifilis a large embedded beneath the epithelium of the body and gills.
Of fish to see a white spot size from 0.5 to 1.0 mm, usually epidemic in the winter. Protozoal infection is.
The shape is oval or round mass around the nucleus is seen as a horseshoe. Division of these parasites.
Is fast. Can create up to 1,000 larvae (Fig. 3) should be isolate sick fish from the fish.
Immediately with clean water. Treatment is difficult because these protozoa are placed under the skin of fish.
During Holy et al (2541) reported that the best way to prevent entrapment of fish for about 7-10 days before being released into the culture.
To check for parasites or not. Formaldehyde is often used to treat 25 ml per 1,000 liters of water with the green hat at 0.1 client.
Grams per 1,000 liters of water and air. Should adjust the water temperature between 29-30 degrees Celsius.
The adult trophozoite embedded in the skin of fish. The complete sexual trophont be out of the fish.
Trophont swimming freely within a barrier coat can create up to 1,000 embryos Embryos were tomite.
Released fish and swim freely to find the target tomite to penetrate the skin of a fish.
trophozoite.
4. A serious threat to fish.
Fish tick (Argulus sp.), Which has a flat circular shape approximately 5-7 mm can be seen by the eye.
I have 8 legs, parasites, they will hook 2 (Fig. 4) Tick the fish will stick with the fish. The blood-sucking fish to fish.
Irritation of the skin lesions of fish. Formalin treatment to 2.5 ml in 100 liters of water.
Soak for 24 hours, then drain the water by 50%.
5. Disease, anchor worm.
Crustacean parasites that have caused the scientific name Lernea sp. Found in freshwater fish with a worm pellets.
Anchor has a cylindrical shape. Large can be seen with the naked eye. There may be up to 2 cm long worm.
It’s like an anchor, the anchor is down below the surface. Finally, a bag of eggs, a pair (Fig. 5) after the parasites are.
Spawning, then dying. The fish were ulcerated area. Roy noticed a red bruise. The worm infected more easily.
Anchor anchor worm is a parasite of fish is a female only. The nematode parasites and worms, which are the spines.
Are detected in some, but not much.
Diseases caused by bacterial infection.
The bacterial infection is similar is that there is bleeding. Ulcers of the body fin erosion, and water.
Bowel disease is important not to eat such food.
1. Resulted from a Gram-positive bacteria. Mycobacterium spp.
Cause chronic infection in both freshwater and saltwater fish. Difficult to maintain the fish are not weak.
Diet, weight loss, pale and fade into the scales and fins, bulging eyes, skin and scarred pit box.
Abdominal swelling and inflammation are often scams, gray, white blotch in the liver, kidneys, heart, spleen, scattered, and muscle (Fig. 6) of this disease.
Contact with the skin. Through the egg and sperm. In addition, the fish may have been infected from food organisms such as flea larvae.
Red worms, Department of Riga (2543) noted that the disease is in touch with people through infected wounds. We should get rid of and kill the infection.
Well when the fish is cleaned with chlorine dispenser.
2. The disease is caused by an Outdoor Mobile NASDAQ (Aeromonas hydrophila).
This bacteria live in water is a source of high amounts of organic matter. Whether stress.
The carrier mobility. Oxygen is low. Feeding the poor. There are a lot of parasites Ekaakin.
Induction causes the fish to infection.
Infected fish will swim fin erosion has been sluggish, not eating a hole deep wound bleeding, abdominal swelling.
Yellow with liver and intestinal bleeding. Pain, abdominal swelling, usually found in the goldfish.
Preventive maintenance, pond or aquarium accordingly. And the fish were released immediately.
Not to be the source of infection treated with oxytetracycline (terramycin) at a rate of 55 mg of fish food 1.
Kg per day for 10 days, the drug should be used to feed the fish.
A. hydrophila causes disease when the fish is stressed. Especially after the ball carrier.
Fish, fish should not be packed too tightly. Adding 0.1 to 0.5% sodium chloride to control the balance of ions in the body.
Fish lost due to stress. The salt also reduces the toxicity of ammonia and nitrite accumulation.
In transit.
3. A disease or disorder columnist Chris in the water.
Caused by the bacteria Flexibacter columnaris infection in fish is when the stress of transportation.
Especially during the summer. I have a pale discoloration of the mucous is very unusual to have fin erosion, gill erosion may have.
A yellow substance formed around the wound. Salt should be used in the handling or use of potassium permanganate to reduce infection.
Fish may be injured due to transport. The treatment of bacterial infections of the skin by soaking in water.
Ruby 2-4 ppm.
Diseases caused by fungi.
Saprolegnia fungi are most common infection in the eggs that are hatching are bad. The fluffy white.
Gray-flannel-like fish, especially wound infections. Wound that was destroyed by a parasite or
Wounds from handling or transportation. Fungi are a group of fibrous white scar around the island. Is rooted in the South.
The skin is extended. Spores can connect to other fish in the pond. Infected fish will stop eating.
And death. Protected by the fish in the sink temperature is too low. Have to get rid of leftover food and dead fish.
Infections out of the aquarium. Potassium permanganate treatment may be supplemented or Betadine.
Diseases caused by viruses.
The diseases caused by viruses has not been extensively studied in fish in Thailand. Probably because there are not.
Development of cell culture virus in the laboratory. It is believed that a virus that harm fish.
Cause tumors or bumps on the body of fish. However, the virus without treatment. So fish out the disease.
Been destroyed. Then clean the cabinet room.
Diseases caused by poor water quality.
Because fish are cold-blooded animals. Properties of water change will affect the functionality of the system.
Fish is very much in the body. Fish growth may slow, weak, leading to infection, the easier it should be.
The use of plants in the aquarium water in moderation. To remove ammonia waste from the fish as
Ammonia accumulated in large amounts will cause fish irritation. Difficulty breathing and can cause fish death.
If using tap water to raise fish. Bring the water to stay or oxygen to remove residual chlorine in the water.
Sodium sulfate may be used to plug in to remove residual chlorine. Excessive chlorine The pale fish down there.
Mucus secretion comes out than usual. The weak and dead fish.
The air and water to maintain adequate levels of oxygen in the water needs of fish.
Beauty of the ponds to assist in the disposal of the residues in the pond as well. However, in transition.
Water must be careful not to change the temperature of the water at different temperatures of water in the pond too. This may cause the fish.
Or weak shock easily.
Caution also is. The use of detergents, cleaning the aquarium. Must ensure that No residue before putting the fish down.
Detergent to break the mucus, which helps cover the fish. The weak fish. Infected easily.
Department of Riga (2543) stated that tobacco smoke contains nicotine which is a component. Nicotine is a very water soluble.
Size is 5 ppm can kill fish Hagnkiog die within 5 minutes when the fish is treated with nicotine.
Pectoral pale walls of the fish may have died before the whole thing.
Diseases caused by malnutrition.
Problems often caused by faulty diet. Loss of nutrients during the manufacturing and.
Storage is not good. Include a common disorder. Vitamin C deficiency. The skull, causing strong Bleeding under the chin with the crook.
Eat less later in the disease. The lack of B vitamins. Fish will swim the body convulsions. The swelling and growth.
Decrease in vitamin A deficiency and fish eye swollen belly bulging.
If you are feeding organisms such as marine flea larvae or mites. Should be soaked in potassium permanganate before. To kill germs.
Differences that may be contaminated with these foods.
To prevent fish.
Disease prevention. A key point in all types of aquaculture operations. It helps in saving.
Cost required to adhere to that. It is better than cure. Normally, patients often do not eat fish made by mixing the drug.
Food is difficult. Selection of species and sources. The history of breeding and performance.
Quality assurance. As well as after-sales service. Shopping should not be too far. If you choose not to be there.
And good transportation. To reduce the trauma and loss in transit. If the fish comes from other sources should be soaked with the drug.
Chemicals first. Attached to the disease. There should be a condition of the fish before being released into the culture. The food.
Appropriate quality and quantity. Not too much I make. Water perishable. Food storage in place.
In order not to deteriorate the quality of the food before the fish. Feeding organisms. Should be cleaned with potassium permanganate before.
(Clubs, student, Faculty of Fisheries 2534) to reduce contamination of germs. Should choose foods that are appropriate to the size.
And species of fish. Fish should be fed as soon as they start to drop. The fish are accustomed to the conditions in the aquarium.
Fish and water quality in the standard. Do not make sudden changes in water quality have
The air to provide oxygen. The residual water sludge and food waste on a regular basis. Has been replaced.
Water occasionally. Control of water to suit the type of fish. Notwithstanding any other provision so that it does not release the fish.
Too dense. This may cause stress and fish. Infected easily. Always check the health of aquatic animals is always a fish.
