What do you need to know about aquaculture management before and during typhoon?

On the eve of the typhoon: First, keep abreast of the weather.

Pay close attention to the latest local weather forecast, pay close attention to weather changes, and know the arrival time, wind level and landing (impact) place of the typhoon in advance;

Second, do a good job of inspection and reinforcement.

Check whether the pond foundation needs to be reinforced to avoid fish escaping due to dam break; Check whether the line leaks electricity and is prone to short circuit due to moisture, and whether the generator, aerator and other equipment are operating normally; Check whether there are potential safety hazards in the factory shed, and reinforce the roof of the warehouse shed to prevent the rain from wetting the feed and medicine.

Third, deal with it in advance

Appropriately reduce the pond water level to prevent the rainstorm water level from rising; Reduce the amount of feeding or stop feeding to reduce the burden of digestion; For the cultured animals that meet the listing standards, they can be harvested in advance before the typhoon comes, so as to minimize the economic losses caused by the typhoon.

After the typhoon:

I. Production resumption

Timely do a good job in post-disaster treatment and post-disaster production recovery. Pay close attention to repairing ponds and various breeding facilities destroyed by floods, reinforce dams, and remove excess sludge from ponds in time; Dead fish, sick fish and aquatic plants swept up by typhoons after the disaster should be removed immediately to prevent rotting and polluting water bodies; Timely repair power supply lines and oxygen-increasing equipment, and restore normal oxygen-increasing as soon as possible. Pay attention to electricity safety when repairing lines after rain to prevent electric shock.

Second, adjust the water quality

Because a large number of harmful substances enter the water body after the rainstorm, the water quality is bad, and the cultured animals are prone to strong stress. Use Youjiling to complex the toxins in water in time, inhibit the generation of harmful substances and stabilize the algae phase. More importantly, it can also reduce the stress response caused by changes in the external environment, so it has become a necessity for many farmers. In addition, after the disaster, it is necessary to start the aerator in time and replenish fresh water, raise the water level appropriately and replace the bottom water of the pond as much as possible. It is necessary to adjust water quality and biological community by adding water, changing water and planting grass.

Third, scientific feeding.

After the typhoon, because there are fewer fish in the pond, we should feed high-quality feed in time. Adhere to the principles of timing, quality determination, positioning and quantification in feeding to ensure that the cultured animals are full, eat well and grow healthily and rapidly. Stirling should be mixed into feed, which can not only improve intestinal health and enhance intestinal immunity; It can also protect the liver and gallbladder and promote digestion and absorption. In addition, Sterling has played an active role in attracting food and promoting growth.

Fourth, prevent diseases.

Observe the feeding, growth and activity of cultured animals, and take countermeasures in time if any abnormality is found. If the behavior of fish is abnormal or a small number of deaths occur, it is necessary to check the situation of fish by sampling and diagnose the disease type in time; Strictly disinfect seedlings, grain fields and tools to prevent problems before they happen, and try to avoid irritating drugs when using insecticidal drugs and disinfectants.

Farmers should not be careless, pay close attention to the forecast and early warning information and defense guidelines issued by meteorological, marine and hydrological departments, and raise their awareness of disaster prevention and avoidance; Take scientific, correct and effective management measures, cooperate with the use of Youjiu products when necessary, and strive to minimize the impact of typhoon.
