Shrimp when using photosynthetic bacteria
Photosynthetic bacteria is a kind of high-tech biological products. The bacterial cells contain more than 60% of protein, and are rich in B vitamins, amino acids and growth promoting factors. They are high quality and safe nutritive feed additives. For shrimp farming can activate the shrimp immune system, enhance resistance to disease, promote metabolism, and thus increase feed remuneration. In addition, photosynthetic bacteria can also degrade and remove harmful hydrogen sulfide and phenols, amine toxicants, and absorb heavy metal ions, so that the shrimp pond water quality can be purified. When the dissolved oxygen in the water of shrimps declines, the PH value decreases, and the water quality deteriorates, 5 kg of photosynthetic bacteria liquid (concentration of 1 billion to 2 billion bacteria per milliliter) is applied at a depth of 1 meter per acre, which can make the water stable and transparent. As the pH value increases, the dissolved oxygen in the water, especially at the bottom of the shrimp pond, increases and the shrimp body vigor increases. Photosynthetic bacteria should be started before the shrimps are released, and they should be applied every 10 to 15 days until they are harvested. Photosynthetic bacteria can be mixed with clean and fine sand and spread evenly in the whole pond, or diluted with photosynthetic bacteria solution and then sprinkled in the whole pond. It is also possible to add 3% photosynthetic bacteria liquid to the shrimp feed. Photosynthetic bacteria cannot be used together with disinfectants such as quicklime and bleach. The use of photosynthetic bacteria on a continuous rainy day is not effective and should not be applied.
