Detailed explanation of measures for shrimp farming before and after a typhoon
Measures for shrimp farming before and after a typhoon
(Agricultural Wealth Network) In coastal areas, adverse weather such as typhoons and heavy rain often occurs. The impact of adverse weather has an enormous effect on the ecological environment of farmed shrimp. In particular, the torrential rain brought when a typhoon passes through can cause stress in shrimp, and after the rain, shrimp diseases are very likely to occur, causing farmers to harvest and sell off large quantities of shrimp. Although adverse weather is highly harmful to the shrimp farming industry, we can reduce farming risks by adopting certain preventive measures.
Measures for shrimp farming before a typhoon
On the eve of a typhoon's arrival, the first thing is to raise the water level of the shrimp pond as much as possible and increase water storage, because when a typhoon passes through it will inevitably bring rain, thereby causing changes in temperature, salinity, pH, transparency, dissolved oxygen and so on. This will cause stress reactions in shrimp. Raising the water level in time effectively reduces the impact of rainwater on temperature and salinity, and will play a very good buffering role. Second, while maintaining a certain water level, a large amount of live bacteria preparations and water-conditioning agents should be used, such as Nitrifying No. 1, Water Protection Probiotics, Water Cultivation Ecological Treasure, Ecological Fertilizer Water Paste, etc., to adjust water quality to the best condition.
Practice has proven that dense water color and low transparency make it easier to withstand disastrous typhoon weather. Dense water color and low transparency indicate that planktonic algae in the water are abundant, and their high-density presence can produce abundant oxygen, which is more favorable for promoting shrimp growth and maintaining water body balance. A large dominant population of live bacteria can not only degrade harmful substances in the water body such as ammonia nitrogen, nitrite, hydrogen sulfide and organic acids, but can also absorb and utilize macromolecular organic matter, mineralizing organic matter into inorganic salts to provide nutrients for algae growth. This forms a benign cyclic ecosystem in the shrimp pond. It maintains the stability of the bacterial phase and algal phase in the shrimp pond. This is of great significance for maintaining stable water color and a good water quality environment during a typhoon. Therefore, before a typhoon arrives, splash Water Cultivation Ecological Treasure + Green Water No. 1 over the whole pond, and combine this with oral administration of Premium Lactic Acid Bacteria, Jin Wei An and Wei Mian; on the one hand this creates a good water environment, and on the other hand it can enhance the resistance and anti-stress capacity of shrimp.
Measures during a typhoon
During a typhoon, aerators must be kept running at full capacity to prevent oxygen deficiency in shrimp. Before and after a typhoon arrives, weather changes abnormally, and low-pressure weather accompanies both periods. At this time the water environment changes rapidly, and dissolved oxygen in the water body generally shows a low dissolved oxygen state. When a typhoon brings rainfall, running the machines at this time helps solve the phenomenon of stratification of water temperature and salinity. This minimizes the range of changes in water temperature and salinity and reduces the possibility of stress in shrimp. If the shrimp pond has convenient drainage, the upper layer of fresh water should also be drained off, to keep temperature and salinity relatively stable as much as possible. During this period, timely splash Detoxification Anti-Stress Essence Liquid over the whole pond to control stress in the water body caused by abnormal weather, avoid phenomena such as algal collapse and water transition, and at the same time splash Jin Wei An over the whole pond to reduce shrimp deaths caused by water quality changes.
Measures after a typhoon
After a typhoon, especially severe and prolonged heavy rain or torrential rain, the ecological environment of the shrimp pond is affected to varying degrees, and the ecological environment of the shrimp pond loses balance or completely loses balance. It is very difficult to restore in a short time, causing pathogenic bacteria to multiply rapidly. This leads to abnormal conditions in the water environment or in the shrimp within 1-2 days, and even outbreaks of disease. Therefore, the primary task after a typhoon is to control the reproduction of pathogenic bacteria in the pond. Because after a typhoon the shrimp bodies have all suffered severe damage to varying degrees and their constitution is relatively weak, some disinfectants will strongly irritate the shrimp bodies, causing shrimp death, and will also affect the growth of algae. We should choose fermented Chinese herbal medicines for disinfection, such as Jin Wei An, Wei Mian, Multi-effect Antiviral, Jin Fang Liver Protection Treasure, etc., which can all be used to clear pathogenic bacteria from the water body, while also regulating water quality and promoting algae growth; on the second day, use Detoxification Anti-Stress Essence Liquid to detoxify the water body; on the third day, use Ecological Fertilizer Water Paste together with Green Water No. 1, soak in water for 2 hours, then dilute in water and splash over the whole pond to cultivate healthy and excellent water quality.
