When the body of loaches has problems, it is necessary to determine the specific cause of the problem before taking corresponding treatment measures. The following are some common physical problems and treatment methods of loaches: 1. Common diseases and treatment methods
1. Symptoms of Red Fin Disease (Red Skin Disease, Corrosive Fin Disease): After being infected, loaches may experience redness, swelling, and ulceration on their surface, fins, abdomen, and anus. Some may also develop bleeding spots, muscle ulceration, and fin erosion. Additionally, there may be redness and swelling of the anus and erosion of the intestinal tract. Treatment method: Soak in a solution of tetracycline or aureomycin containing 10~15 micrograms per milliliter for 10~15 minutes, once a day; Or sprinkle 1 milliliter/liter of bleach powder all over the pool; Or soak the diseased loach in a 3% saline solution for 10 minutes; Alternatively, after improving the water quality, use 2~5 milligrams/liter of hexamethylenetetramine for several consecutive days.
2. Symptoms of enteritis (such as head rot disease and aconite disease): The diseased loach moves slowly, stops feeding, and its body turns black and green. Its head appears special, and its abdomen shows red spots. The intestinal tract is congested and inflamed, and the anus is red and swollen. Mild cases may have blood and yellow mucus flowing out of the abdomen, while severe cases may turn purple and die quickly. Treatment method: Add "Multidimensional" to 5% of the feed weight, mix and feed for a few days; Or feed 2 grams of norfloxacin mixed with every 50 kilograms of loach; Add 1~3 milliliters of florfenicol and 3 grams of vitamin C1 per kilogram of feed, stir well, and feed continuously for 3 days; Alternatively, for every 50 kilograms of loach, mix 5 grams of compound sulfamethoxazole with 0.5 grams of ascorbate and feed continuously for a few days.
3. Symptoms of water mold (skin mold, white disease): white cotton like water mold adheres to the surface of the fish body. Treatment method: Soak the diseased loach in 10 milliliters/liter of malachite green solution for 20 minutes, or soak it in 3% salt solution for 5-10 minutes; Or soak in 0.5 \ \~0.8 mg/L methylene blue solution for 20 minutes; Or sprinkle the entire pool with a mixture of 0.02% saline and 0.01% baking soda.
4. Symptoms of protozoan gill rot disease: The gills of the diseased loach are significantly red and swollen, the gill cover is open, the gills bleed, the gill filaments turn white, the mucus increases, and the gill cover is half open. Slow swimming, thin body and dull color of the loach. Difficulty breathing, often floating on the water surface, stopping eating in severe cases, and ultimately dying from respiratory obstruction. Treatment method: Dissolve 0.1~0.2 grams of dichlorvos in 10 kilograms of water and soak the diseased loach for 5~10 minutes; Or sprinkle 90% dichlorvos in water throughout the pool to achieve a drug concentration of 0.3 milligrams to 0.5 milligrams per liter; Or timely use insecticides to kill parasites on the surface of loaches.
5. Symptoms of fever: Loaches are restless and entangled with each other, their skin and tail fins lose their original luster, their color is dull, and a gray white opacities appears on their surface. Treatment method: Immediately replace with new water; After the onset of the disease, a 0.07% copper sulfate solution can be used to spray the entire pool at a rate of 5 milliliters per cubic meter of water; Feed 2 to 5 grams of Huanglian Baidu Powder per kilogram of feed, take continuously for 2 to 3 days, and pay attention to adjusting the water temperature during this period; Sprinkle 1 to 3 grams of immunostimulant per cubic meter of water in the pool. 2、 Injury handling
For injured loaches, medications such as ofloxacin and erythromycin can be used for treatment. These drugs are broad-spectrum antibiotics that can be used to treat bacterial infections. When using, follow the instructions of the medication, pay attention to the concentration and duration of use, and avoid excessive use that may cause drug residue problems. At the same time, providing suitable water quality and environment to help loaches recover their health. 3、 Preventive measures
1. Maintain water quality: Regularly change the water, keep the water clean, and avoid deterioration of the pool water.
2. Reasonable breeding: Pay attention to breeding density and avoid overcrowding.
3. Feed quality: Ensure the quality of the feed and avoid feeding spoiled feed.
4. Disinfection treatment: Before releasing the loach species, disinfect them with saline solution, potassium permanganate solution or bleach powder.
When the body of loaches has problems, corresponding treatment measures need to be taken according to the specific situation. At the same time, strengthen preventive measures to improve the breeding efficiency of loaches.
