Xi'an 丨 strong rainfall weather aquaculture management points are released

According to the Provincial Meteorological Observatory on July 8, 2022, an important weather report was released. Affected by the west wind groove and the warm and humid airflow of the auxiliary high -periphery, the weather in our province will appear on the night of July 11th to the 13th. In order to do a good job of rainfall weather, Xi'an Agricultural and Rural Bureau issued the main points of heavy rainfall weather aquaculture management points, and the majority of aquaculture farmers are requested to combine actual reference.

1. Pre -rain prevention as the mainstay

1. Pay close attention to the weather forecast, enhance prevention awareness, and make preparations for rainstorms and rainstorm prevention in advance.

2. Reinforce pond base and anti -escape facilities. Check the pond in advance to be severely damaged and not repaired in time. It is necessary to repair and reinforcement as soon as possible to prevent leakage and collapse. Low -lying areas should increase the height of the ponds in advance, and the ponds are also equipped with a suitable and solid and durable fishing nets around the pond to prevent losses from escaping the water over overflowing ponds. If necessary and conditions permit, the pond water level can be reduced before the rain, and part of the space can be free up to increase the volume volume of the pond.

3. Check the safety of breeding equipment and electricity facilities. Check whether the production facilities such as oxygen hemers, bait machines, and water pushing machines can work normally, whether the wires are aging, the connecting exposure, the disruption of the power gate, and the private pull of the wires. Non -waterproof wires enter the water leakage.

4. Prepare necessary emergency supplies. Conditions can prepare spare generators, pump pumps and appropriate pipelines in advance to prevent electricity at rainy days and facilitate emergency water stagnation.

5. Decreasing air pressure before rain in summer, resulting in a decrease in the solubility of the water body to the oxygen, and the pollutants at the bottom of the water body, which causes the hypoxia of the water to "Pan Tang". Inject new water in a timely manner, use oxygen hemozoa scientifically, spare -oxygen -aged drugs, and strengthen emergency prevention.

Second, strengthen management in the rain

1. In the rainstorm, the oxygen agemptor should be turned on in a timely manner to increase the dissolved oxygen of the pond as much as possible to slow down the death of microorganisms in the pond, stabilize the water phase, and prevent the disease from the occurrence of a large scale.

2. During the rainstorm, less or not feed, reduce the amount of fish and shrimp activities and eat microorganisms, thereby reducing the total oxygen consumption of pond biology.

3. During the summer thunderstorm, try to reduce artificial open -air activities, avoid using metal umbrellas, tools, mobile phones, etc. to prevent injuries to lightning.

4. Remember "life safety first" to occur in heavy rainwater, and take necessary measures to remedy on the premise of ensuring personal safety. Do not leave the water to reduce the impulse to reduce losses.

3. Remed up after the rain

1. If the rainstorm becomes a disaster, it should be done in time after the rain, such as dead fish and diseased fish. The aquatic plants rolled up by the storm should be removed immediately, and it is harmless to prevent rotten pollution and water quality. At the same time, the number and weight of death aquaculture products are estimated to refer to timely replenishment of seedlings.

2. After the disaster, it is necessary to quickly repair the pond dams and various breeding facilities rushed by the flood, strengthen the dams of the dam, timely remove the too much silt in the pond, and restore the production capacity as soon as possible. Aquatic facilities such as oxygen -aged machines, water pumps, bait machines soaked in rainwater, should be removed, dry, rinse and maintained for maintenance and maintenance in order to restore production as soon as possible.

3. Strengthen disinfection work. For fish and shrimp ponds, low -stimulating disinfection agents (such as active iodine, diptives of hydraulics, etc.) should be used for disinfection to effectively prevent the body's body ulcers, rotten skin and other secondary tails caused by bruises. disease. For fish-free ponds, dry the water as soon as possible, expose the till, and disinfect the ponds and surroundings with 100-150 kg/mu for lime.

4. After heavy rain, regulate the water quality. If possible, you can take out the muddy water in time to replace the new water; for the pond where the water quality becomes clear, the biological bacteria fertilizer, compound fertilizer, etc. to keep the pond with sufficient amount of fertilizer Excessive and intensive ponds with too much organic matter at the bottom of the pool. It is recommended to apply micro -ecological preparations such as optical bacteria and bacteria, and the bottom quality improvement agent, and at the same time, the oxygen aggregate is used to avoid hypoxia.

5. Timely replenish seedlings after disaster. Observe and judge the situation of pond escape fish, fish and shrimp that stress and death, to find out the amount of biological quantity in the storage pond and determine the variety and quantity. Soak the fish species and shrimp seedlings before entering the pool for 3-5 minutes to prevent the spread of disease bacteria for 3-5 minutes.

6. Strengthen post -disaster breeding management. The focus is on full feed and fertilizer. The feed should be appropriately added, immune polysaccharides, liver protection, immune polypeptides, etc. to improve the resistance of aquatic products. If bacterial diseases have occurred, antibacterial drugs need to be added to be added as early as possible.
