What are the precautions for using swamp red pseudomonas in aquaculture?

      When using swamp red pseudomonas in aquaculture, attention should be paid to the following aspects to ensure its optimal performance and avoid adverse effects on aquaculture:

      Storage and use time: Marsh red pseudomonas bacterial agents are mostly live bacterial preparations, and should be stored strictly according to product instructions. Generally, they should be stored in a low temperature, cool, and dry place, avoiding direct sunlight and high temperature environments to prevent bacterial inactivation. At the same time, attention should be paid to the shelf life of the product. Expired microbial agents can greatly reduce or even lose their activity, and cannot achieve the expected use effect. When using, try to choose to do it on a sunny morning, when the dissolved oxygen in the water is relatively high and the light is suitable, which is conducive to the rapid reproduction and growth of bacterial strains. Avoid using in rainy or evening weather, as the dissolved oxygen in the water is low during these times, which is not conducive to the survival and effectiveness of bacterial strains.

      Correct usage method: Before use, the bacterial agent should be shaken thoroughly to evenly distribute the bacterial cells, ensuring consistent effectiveness. Administer according to the recommended dosage and frequency of use of the product, avoiding arbitrary increase or decrease in dosage. Low doses may not achieve the expected water quality improvement and growth promoting effects; Excessive dosage may lead to an imbalance of microbial communities in the water, and even have adverse effects on aquatic animals. Generally speaking, the dosage can be increased appropriately when used for the first time or when the water quality is poor, and adjustments can be made later based on the water quality and breeding stage. When spraying microbial agents, they should be evenly sprayed throughout the entire aquaculture water body to ensure that the water in each area can receive sufficient bacterial strains. You can first dilute the bacterial agent in an appropriate amount of water, and then spray it all over the pool to improve the uniformity of spraying.

      Combination with other medications: During the use of Pseudomonas aeruginosa, it is important to avoid the simultaneous use of disinfectants, antibiotics, and other medications. These drugs have strong bactericidal effects and can kill swamp red pseudomonas, rendering them inactive and unable to exert their intended effects. If it is necessary to disinfect or treat diseases in aquaculture water bodies, swamp red pseudomonas should be used after a certain time interval (usually 5-7 days) after the use of drugs. Similarly, disinfectants and antibiotics should not be used within a few days after using Pseudomonas aeruginosa. In addition, when using some water quality improvement agents, it is also necessary to pay attention to compatibility with swamp red pseudomonas to avoid chemical reactions that may affect the effectiveness of use.

      Adaptability of aquaculture environment: Different aquaculture environments may have an impact on the effectiveness of using swamp red pseudomonas. Before use, it is necessary to understand the environmental parameters such as temperature, pH value, and salinity of the aquaculture water. The swamp red pseudomonas is suitable for growth and reproduction in an environment with a water temperature of 25-35 ℃ and a pH value of 6.5-8.5. If the water temperature is too low or too high, or if the pH value exceeds the appropriate range, it will affect the activity and growth rate of the bacterial species. For aquaculture environments with high salinity, it is necessary to choose swamp Rhodopseudomonas strains that are adapted to the seawater environment; For freshwater aquaculture environments, strains suitable for freshwater should be selected. At the same time, attention should be paid to the transparency and dissolved oxygen content of aquaculture water bodies. Maintaining a certain degree of transparency and sufficient dissolved oxygen in the water bodies is beneficial for the photosynthesis and growth of swamp red pseudomonas.

      Observation and monitoring: After using swamp red pseudomonas, it is necessary to closely observe the activity, feeding, and water quality changes of aquatic animals. If abnormal behavior is found in aquatic animals, such as floating heads, reduced feeding, or if the water quality has not improved significantly or even deteriorated, the reasons should be analyzed in a timely manner and corresponding measures should be taken. Regular monitoring of water quality indicators such as ammonia nitrogen, nitrite, dissolved oxygen, pH value, etc. can be conducted to understand changes in the water body and evaluate the effectiveness of using swamp red pseudomonas. According to the monitoring results, adjust the dosage and frequency of use reasonably to ensure the ecological balance of aquaculture water bodies and the healthy growth of aquatic animals.
