1.Adjust the temperature difference:Avoid high temperature exposure during the transportation of seedlings, seedlings have been close to bacteria, do not rush to open the bag and put seedlings when transporting to the destination, the seedling bags should be put into the pond first, about 30 minutes can make the temperature in the seedling bag and the water temperature of the seedling pond balance.
It is best to do so around 9 a.m. or around 5 p.m. and avoid direct sunlight.
3.Seedling treatment:(1) Before going down to the pond:
After adjusting the temperature difference, mix well with a set of mold** and a packet of splashed ginger with 4 cubic meters of water, then soak the fry with a strainer for 30 seconds to one minute, and then put them in the pond. (2) After going down to the pond:After adjusting the temperature difference, the seedlings are directly put into the pond, and after being put in, they are splashed with mildew ** and splashed ginger with water, and each set is 3 acres.
4.Seed cultivation: After the seedlings are planted in the pond, use Yumei + spores + algae seeds every ten days to cultivate phytoplankton and zooplankton, and use three acres for each set.
1. Prevention:Mold-prone monthly period for external use, mildew ** and splash ginger twice, with water to splash the whole pool, each set with three acres.
2. Method:External mildew ** and splash ginger with water splash the whole pool, for two days, each set of 2 acres, the dose is increased for serious conditions, and the use of warm water of about 40 degrees can be used in winter.
1. Prevention:Parasite-prone monthly period is taken for 3 days per month, and the method of use: 20 kg of feed per package of fiber is fed, 30% of the usual feed amount is fed every day, and only one meal is fed every afternoon, which can effectively prevent the reproduction and parasitism of wheel worms and ring worms.
2、**
Wheel worm:Internally take Fangcao fiber, mix 10 kg of feed per bag, and after two days of internal use, externally use mildew** and sprinkle ginger once, each set of three acres. Ring Worm:
External use of avermectin once, 3-4 acres per bottle, splashed with water in the whole pool, when there are more parasites, it can be used for two consecutive days. Note:Weather conditions must be clear on the day of use.
The next day, apply mold for external use** and sprinkle ginger once, three acres per set.

Prevent over-dense breeding and strengthen feeding management;
At the onset of the disease, use pure chlorine dioxide grams of cubic meters, and sprinkle the whole pool for disinfection;
At the same time, allicin was fed for 3 to 5 days. After the fifth day, sprinkle the whole pool with enzymatic prebiotic grams of cubic meters.
Hydromycosis Cause: Caused by Hydromould infection. Disease Symptoms: Water mold does not infect healthy and undamaged tilapia.
-
There are still many diseases caused by tilapia. For example, Aeromonas motilis. Pseudomonas. Edwardsia. If you want to prevent such a disease, you must first pay attention to changing the water regularly. Feed some resistant drugs in the feed.
-
For example, you will have a cold, fever, runny nose, and you can't eat or even have nosebleeds, and you will always urinate frequently, so you can choose to eat more vegetables and fruits.

Hello I think that in general, tilapia survive with a temperature branch width of 15 37, while the lethal temperature is below 10 Cause of death. Most of the deaths of tilapia occur after a sudden drop in temperature for 2 to 3 days, and when the temperature rises again. Some of them are concentrated and mass deaths, while others are deaths that continue to occur for several days in a row.
The diseased fish were examined, and in appearance, the body color of the fish was dull and less shiny, and the body shape was thin; proptosis, opacity and whitish lens of the eyeball; The abdomen is distended, and the epidermis is congested, but there are no abnormal symptoms in the fins and gills, and there are no parasites on the body surface. Anatomical examination, it can be seen that the abdomen of the fish is filled with water, and the liver has lesions, mostly yellow, light yellow, and there are swelling and fat masses, the above symptoms all appear in the diseased fish examined, but the manifestations are slightly different due to the different severity of the disease. Thus, the exclusion of parasitic and viral diseases can preliminarily determine that the fish are suffering from the same bacterial or nutritional disease.

Hemorrhagic disease, hepatobiliary disease, parasites, white stool, these are all common diseases, which can be used with some drugs in a timely manner, such as: Saiyouyu, there are more farmers around.

Summary. Dear is happy to answer for you, according to the latest data, the results of the query are: fat accumulation disease manifestationsSymptoms:
The body shape changes, the swimming is slow, the disease resistance is reduced, the hypoxia is susceptible, and the head is easy to float. Control method: improve the bait formula, reduce the fat content of the formula, and increase the crude fiber content.
Vitamins B, C, and E should be added to the bait. Strengthen water quality control, and use some safe disinfection products when necessary to ensure that the water quality is clean and refreshing.
We are happy to answer for you, according to the latest data, the results of the query are: fat early and cautious accumulation disease symptoms: body shape changes, slow swimming, decreased disease resistance, easy hypoxia, easy to float head.
Control method: improve the bait formula, reduce the fat content of the formula, and increase the crude fiber content. Vitamins B, C, and E should be added to the bait.
Strengthen water quality control, and use some safe disinfection products when necessary to ensure that the water quality is clean and refreshing.
Tilapia has a large belly and has fluid and gas in the intestines.
We are glad to answer for you and inquire for you: the treatment arrangement will take comprehensive measures of external splashing and internal administration. Topical:
On the first day, Jinxin bottom net 15 bottles of the whole pool dry sprinkled. The next day, 2 kg of 10% monochlorine dioxide powder + 5 bottles of Jinxin sulfur jifloxacin, dissolved separately, then mixed evenly, fully diluted and sprinkled throughout the pool. On the third day, Jinxin Hemostasis Pioneer No. 2 kg + 4 kg of three yellow powder mixed and soaked for 3 hours, then added water and splashed the whole pool.
Internal: Buy 50 kg of tilapia puffed pellet feed plus 200 grams of Jinxin pancreatic and renal virus Kang, 800 grams of sepsis and deficiency powder, 200 grams of Sudi, 200 grams of Kangdi, 100 grams of binder, mix and feed evenly, and feed for 4 days.
I asked what the disease was.
According to the latest data, the results of the query are: tilapia stomach is dry, intestinal fluid and qi is what is the disease: tilapia intestinal ascites is the pathogenic bacteria that first infect the intestine, forming inflation and intestinal water, the intestinal wall is thin and damaged, intestinal water enters the abdominal cavity from the intestine to form ascites, ascites causes abdominal distention, abdominal distension causes eye defeat bulbar protrusion, etc., and the stress causes rapid death after the disease is serious.
I asked one in the morning and said there were parasites.
Yes, it is a large stomach with edema and gas in the intestines.
It's not parasites.
There are no parasites.

<> the disease is caused by bacteria. In the early stage of the disease, there are different degrees of hyperemia and hemorrhagic lesions on the head, trunk and fins, and the scales around the lesions are loosened and partially fall off, and the lesions gradually festered with the development of the disease, and in severe cases, the bones may rot. The liver is brown, the gallbladder is large, and the fingers are dark green.
This disease occurs during the period of factory high-density scattered pre-breeding and wintering, due to the high stocking density, large changes in water temperature, poor water quality, and poor feeding management. It can affect everything from fingerlings to broodstock.
Ways to prevent it. 1) Strengthen feeding management, keep the water temperature at about 20 during wintering, and maintain excellent water quality to enhance the disease resistance of the fish.
2) Fish ponds are disinfected with quicklime or bleaching powder before stocking.
3) When the outdoor water temperature drops to about 20, the tilapia must be moved into the wintering pond in time, and the fish must be bathed with salt water (4 kg of salt per 100 kg of water) for 5-10 minutes before moving into the wintering pond to eliminate the pathogens on the surface of the fish.
4) During the wintering period, the whole pool should be sprinkled with quicklime once a month, and 20 grams of water per cubic meter should be used to improve the water quality. Matched.
5) During the wintering period, the whole pool is sprinkled with bleaching powder once a month, and 1 gram of water is used per cubic meter.
**Method. 1) In the early stage of the disease, the diseased fish should be transferred to a water body with good water quality and stable water temperature, and fed with high-quality feed, and the condition will gradually improve.
2) Discharge the pool water to 1 4 places first, then sprinkle furazolidone throughout the pool, use grams per cubic meter of water, after 10 minutes, add the pool water to 1 2 places, and then add the pool water to the original water depth after 1 hour. The next day, furazolidone will be mixed and fed, 2 grams per 100 kg of fish on the first day, and l grams per day from the second to the sixth day, generally a course of treatment**. If the condition is severe and has not been cured, the interval of one week can be repeated** for another course of treatment.
3) Broodstock can be injected with streptomycin sulfate into the back muscle, generally 20 mg per kilogram of fish, which can be **.
As the name suggests. There are many types of kidney deficiency. Yin deficiency, thief. Hot flashes. Yang deficiency and four chills.
