Since the beginning of the summer, a variety of comprehensive diseases such as sputum detachment and septicemia have occurred successively in the eel breeding pools in Fujian Province, causing serious deaths of carp. According to some of the cases we handled in the Minnan region, we hereby propose the following prevention and control methods for reference by the majority of quail farmers. requires attention: Pool water treatment. Since it may take a long time to use drugs and cause deterioration of water quality, it is better to change the water after the end of each medication cycle to keep the water environment clean. In the high temperature period, pay attention to changes in water temperature and water quality. In general, ventilation should be strengthened to increase dissolved oxygen in water, and if necessary, the water level of the medication should be increased. During the period of medication, rapid changes in water temperature cause an increase in the death of carp. In the early stage of disease, the use of antibiotics can not significantly inhibit the development of death. Bromochlorohydrine, chlorine dioxide, blue sky + virus net and other conventional disinfectants can be used to control the development of the disease first, if there is a greater number of deaths, and then use the aforementioned Method processing. Dried fruit products as the name implies, dried fruit products are pre-treated fruits after selection, washing and dehydration to the water content of 15 ~ 25% products. The volume of dried fruit is about 11 ~ 31% of that of Fresh Fruit, and the weight is about 10 ~ 25% of that of fresh fruit, so it can significantly save the cost of packaging, storage and transportation, and it is easy to eat and carry. Common dried fruits are raisins, red dates, dried mango, dried kiwi, dried strawberry and so on.

Symptoms of the disease are as follows: There are obvious symptoms of de-adhesion or septicemia in the early stage of death. The squid's vigor is weakened, and a large number of fish are hung on the bait station or gathered around the sewage outlet and do not ingest food. There are few symptoms of de-adherence in dead carp, and the symptoms of septicemia are obvious. Due to the decrease in the number of symptoms of detackification or septicemia at the later stage, redheads or sacral edema, edema, congestion and edema are common, and other parts of the body surface are basically intact. The individual abdominal cavity is filled with blood and water; blood clots, liver discoloration, and the cocoon filament turns white and swollen. There is a phenomenon similar to fading and whitening after being soaked in water. The number of deaths increased rapidly and the mortality rate was high. The entire onset period of a pool is between 15 days and 20 days.
Effective treatment:
Salt + Chinese medicine + antibiotics, salt can be kept in the 4 ‰ ~ 7 ‰ can, Chinese medicine is mainly Coptis, rhubarb, Astragalus, Eriobotrya japonicus, capillaris, gall and so on, antibiotics can choose to use doxycycline, norfloxacin, Farah Is the Secretary and so on. The medication cycle takes 1 to 2 courses, and it may even take 3 to 4 courses.
After the peak of death, the squid in the pond must be eaten as soon as possible to restore their strength. Can be fed to the bait to eliminate the bacteria in the body. At this time, the water body is sterilized. It is necessary to use a small stimulant drug. At the same time, the squid can be bathed with sea zhongbao, multidimensional, and glucose to promote the squid to eat.
When handling bacteria, care should be taken to check for mold and parasites. If any, treatment should be carried out first. In particular, mold must be killed first. Failure to use antibiotics can cause outbreaks of mold and cause massive deaths. If the number of parasites is small, it can be postponed.
