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

1. Grasp the weather situation in time

Pay close attention to the latest local weather forecast, pay close attention to the 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 the fish escaping due to the dike break; Check whether the line leaks electricity and is easy to get wet and short-circuited, 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 getting wet with feed and medicine.

Third, deal with it in advance

Reduce the water level of the pond appropriately to prevent the rainstorm water level from rising; Reduce the feeding amount or stop feeding to reduce the digestive burden; For the cultured animals that meet the listing specifications, they can be harvested and listed in advance before the typhoon, so as to minimize the economic losses caused by the typhoon. After the typhoon:

1. Production recovery

Timely 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 excessive silt in ponds in time; Dead fish, sick fish and aquatic plants rolled up by typhoon after the disaster should be removed immediately to prevent rot and pollution of water bodies; Timely repair power supply lines and oxygen-increasing equipment, and restore normal oxygen-increasing as soon as possible. Pay careful attention to power 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 intense stress. Use Youjiling to complex the toxins in the water body in time to 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 add new water, raise the water level appropriately and replace the bottom water of the pond as much as possible. It is necessary to adjust the water quality and biological community by adding water, changing water and planting grass.

Third, scientific feeding

After the typhoon, because there are few fish in the pond, it is necessary to 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 eat enough, eat well and grow healthily and rapidly. It is advisable to mix Stirling into feed, which can not only improve intestinal health and enhance intestinal immunity; It can also protect liver and gallbladder and promote digestion and absorption. In addition, Stirling has also played an active role in attracting food and promoting growth.

fourth, prevent diseases

observe the feeding, growth and activities of farmed animals, and take countermeasures in time if any abnormality is found. If the fish behave abnormally or a small number of deaths occur, it is necessary to check the fish's condition by sampling and diagnose the disease types in time; Strictly disinfect seedlings, food fields and tools to prevent problems before they happen, and try to avoid irritating drugs when using insecticidal drugs and disinfectants.

The majority of farmers should not be paralyzed. They should pay close attention to the forecast and early warning information and defense guidelines issued by the three defenses and meteorological, marine and hydrological departments to 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 typhoons.
