What are the benefits of using swamp red pseudomonas in aquaculture?

Rhodopseudomonas palustris is a type of photosynthetic bacteria that has multiple benefits and roles in aquaculture, as follows:

Purification of water quality: Rhodopseudomonas palustris can utilize various harmful substances such as sulfides, ammonia nitrogen, and organic acids to convert them into the nutrients needed for its own growth. For example, it can absorb ammonia nitrogen in water, reduce its concentration in water, and avoid toxicity to aquatic animals caused by high ammonia nitrogen content. At the same time, swamp red pseudomonas can decompose residual organic matter such as feed and excrement from aquatic animals in water bodies, reduce the accumulation of organic matter, lower chemical oxygen demand (COD) and biological oxygen demand (BOD), thereby improving water quality and creating a good living environment for aquatic animals.

Increasing dissolved oxygen: As a photosynthetic bacterium, Rhodopseudomonas palustris can carry out photosynthesis under light conditions and produce oxygen. This helps to increase the dissolved oxygen content in the water, especially in ponds with high aquaculture density. Adequate dissolved oxygen is crucial for the respiration and growth of aquatic animals, which can improve their vitality and disease resistance, and reduce problems such as floating heads and flooding caused by hypoxia.

Regulating the microecological balance of water bodies: After entering the water body, swamp red pseudomonas can rapidly reproduce and become the dominant bacterial group, inhibiting the growth and reproduction of harmful bacteria. For example, it can compete with harmful bacteria such as Vibrio and Escherichia coli for living space and nutrients, reducing the number of harmful bacteria and lowering the risk of infection in aquatic animals. At the same time, it can also promote the growth of beneficial microorganisms, such as some nitrifying bacteria, further improving the ecological environment of water bodies.

Enhancing the immunity of aquatic animals: Rhodopseudomonas aeruginosa in swamps contains rich nutrients such as protein, vitamins, coenzyme Q, etc. These nutrients can be absorbed and utilized by aquatic animals, promoting their growth and development and improving their immune system. Research has shown that after consuming feed containing swamp red pseudomonas, the immune cell activity of aquatic animals is enhanced, their disease resistance is significantly improved, and their resistance to common diseases such as bacterial sepsis and enteritis is enhanced.

As a high-quality bait: Rhodopseudomonas palustris is small in size and rich in nutrients such as protein, vitamins, and minerals, making it a high-quality open bait for aquatic animal larvae. For example, during the juvenile stage of fish and shrimp fry, swamp red pseudomonas can provide them with abundant nutrients, promote the growth and development of juveniles, and increase their survival rate. Moreover, it is easy to digest and absorb, and does not burden the digestive system of juveniles.

Promoting growth and development: The application of swamp red pseudomonas in aquaculture can promote the growth of aquatic animals. On the one hand, by improving water quality and providing nutrients, a favorable growth environment has been created for aquatic animals; On the other hand, the bioactive substances it contains, such as coenzyme Q and carotenoids, can regulate the metabolism of aquatic animals, promote the secretion of growth hormones, accelerate the growth rate of aquatic animals, shorten the breeding cycle, and improve breeding efficiency.
