What should be paid attention to in detail management and key control technology of healthy culture of Monopterus albus?

Most diseases of aquatic animals are caused by stress, which leads to the weakening of vitality, and pathogens invade the body of breeding objects. Therefore, in the practice of anti-stress and anti-stress, the deterioration of water quality and sediment, fright, weather change, abnormal climate, algae bloom and so on are the important reasons leading to the stress of breeding objects. ?

In particular, we need to be alert to the poor water quality caused by algae: algae die under stress, the water environment changes, and the breeding objects will be immediately subjected to joint stress. The stress response of algae is mainly affected by climate, drug use and environmental changes (such as temperature difference, low air pressure, rainy days, wind direction change, splashing irritating drugs, water quality deterioration, sediment corruption and other factors). ?

Sudden changes in the environment will easily lead to "water bloom", "grass decline" and "water change", which in turn will lead to strong stress, reduced food intake, weak constitution and diseases of Monopterus albus. As long as you pay attention, listen to the climate forecast in advance and predict the weather in the next three days. When there are abnormal weather conditions such as sultry and windless, typhoon and rainstorm, continuous rain, uncertain wind direction, seasonal changes such as Chu Qing and Qingming White Dew after rain, it is not advisable to use disinfectants, and use microbial agents with caution or in small quantities; At the same time, we should reduce or stop feeding as appropriate, otherwise it will stimulate the feeding object to have a strong stress reaction, leading to malignant diseases and serious consequences. ?

The correct way: topdressing and cultivating bacteria three days before the weather changes: using new live bacteria king (300ml/μm)+ six-resistant algae culture cream 1 kg (or algae happiness 1 kg) to enhance the stress resistance of algae per μm. 65438+ 0 days before the weather changes, splash water with degradable 250g/μm+ relieving pressure 250g/μm to eliminate or relieve the pressure; If the bad weather lasts for more than 5 days, it should be poured repeatedly 1 time. Feed Jintikang (0.5%), enzymolysis polysaccharide (1%), active garlic treasure (0.5%) and Qingyuan (1%) two days in advance to protect liver and strengthen intestines, and increase the physical strength and immunity of Monopterus albus. During the weather changes, stop drinking water and change water, and reduce feeding. ?

The sudden change of environment, fully preventing and resisting stress, can avoid the occurrence of diseases such as cold, fever, madness, white dew, hypoxia and panic and escape, and resolve the breeding crisis. ?

Warm reminder: In order to prevent the stress reaction caused by weather or climate change, we should develop a good habit of paying attention to weather and meteorological information and predict the weather situation in the next 3-5 days. To know the weather information, you can watch the weather forecast of TV station, listen to the weather forecast of radio station, or subscribe to the short message of the weather forecast, or check the Central Meteorological Observatory or the local meteorological observatory in www.nmc.gov.cn on the Internet to understand the weather dynamics. ?

? Key control technologies: scientific feeding, balanced nutrition, enhancing immunity and promoting growth?

1. It is necessary to mix enzyme-producing probiotics and lactic acid bacteria into feed before feeding (such as Jianchangling, Active Garlic, Herbal Dakang, etc.). It contains not only enzyme-producing probiotics, but also lactic acid bacteria and yeast. ) In order to improve the digestion and absorption of Monopterus albus to high-protein feed nutrition, meet its nutritional balance requirements, and enhance its immunity and disease resistance. The unique alcohol flavor of the product has a strong food appeal. Its powerful compound population advantage of beneficial microorganisms can not only supplement the endogenous enzymes of Monopterus albus, enhance the digestive function and promote the digestion and absorption of feed nutrients, but also effectively inhibit the growth and reproduction of pathogenic microorganisms in the digestive system, maintain the balance of flora in the digestive tract, repair and promote the healthy cycle of microecology in the body and prevent digestive system diseases. ?

2. In the process of culture, the sediment and water quality are well maintained and improved in time, which can reduce the stress response of Monopterus albus; Supplementing nutrition and health care products and trace elements can enhance the vitality and immune disease resistance of eel, improve the transformation and absorption of feed nutrition, promote the growth of eel, reduce the risk and cost of raising eel and improve the breeding efficiency. ?

3. Pay attention to the influence of climate change, algae phase change, water quality change, sediment change, tidal change, physiological change (epidemic situation) and other factors, reduce or stop feeding according to the situation, and don't blindly feed at intervals. ?

According to the weather forecast, 2 ~ 3 days before the weather changes (such as low pressure, sultry weather, typhoon, rainy weather and wind direction changes), in addition to maintaining the water quality in advance, we should also mix and feed the liver-protecting and growth-promoting spirit, active garlic treasure, Jin Taikang and Vito in advance to enhance immunity; During the weather change, the use of materials should be reduced or stopped; After the weather is stable, the above products with liver protection, stomach strengthening, nourishing and immunity should be supplemented in time. ?

During the period of water quality change, sediment change, pH value change, onset, nitrite, ammonia nitrogen and hydrogen sulfide exceeding the standard, measures such as detoxification, water protection and anti-stress should be taken to optimize the water environment, and at the same time reduce or stop materials; After the water quality is stable, the products such as liver-protecting and growth-promoting wine, enzymolysis polysaccharide and Jintaikang will be resumed. , can protect the liver, strengthen the stomach, enhance physical fitness, and will be supplemented in time. ?

4. Pay attention to protecting the liver and gallbladder: nourishing the liver and gallbladder, detoxifying and ensuring the health of the liver and gallbladder function of Monopterus albus are very important for the culture of Monopterus albus. Often adding Jintikang or Ganbaochangling into feed is beneficial to protecting liver and gallbladder, enhancing the detoxification function of liver and gallbladder function, and improving immunity and disease resistance. ?

5. Clean the feeding table to prevent pollution: Use Likang 5 ~ 10 tablets every 3 ~ 5 days and sprinkle them on the feeding table in the morning to prevent and treat diseases caused by pathogenic bacteria polluting feed. ?

Beware of "the disease enters from the mouth";

Monopterus albus is an omnivorous fish, mainly feeding on carnivorous food, and likes fresh food such as eat small fish, shrimp, earthworm, fly maggot, plankton, mussel, insect larva and snail. Earthworms and fly maggots are the most palatable bait for Monopterus albus, but they are also carriers of various bacteria, viruses and parasites. It is an important source of infection of Monopterus albus diseases. Wild miscellaneous fish raised by farmers have hardly been treated, and a large number of harmful bacteria and viruses are attached to wild miscellaneous fish, especially deteriorated wild miscellaneous fish. Monopterus albus brings harmful viruses and germs or toxic heavy metals or drug residues into the body during ingestion, thus causing diseases, such as hepatomegaly, liver erosion and necrosis, enteritis, parasitic diseases and so on. ?

Before feeding earthworms, fly maggots and wild fish, active garlic should be mixed with bait to eliminate harmful substances (1 bottle can be mixed with 100 kg fresh bait). The bactericidal and bacteriostatic ability of fermented natural garlic is 5-8 times that of common antibiotics, with no residue and no drug resistance. Active garlic can be widely used to treat fresh bait in pollution-free culture of Monopterus albus, which plays a very good role in improving the quality of Monopterus albus. ?
