1. Purifying water quality Because the water body with high-density culture contains a lot of fish manure, residual bait and fish medicine residues, ammonia nitrogen, hydrogen sulfide and some harmful substances produced by its corruption directly pollute the water body and sediment. Light pollution will cause fish discomfort, increase feed coefficient and slow growth. When PSB accumulates to a certain extent, it can effectively absorb harmful substances such as ammonia nitrogen and hydrogen sulfide, form bacteria themselves, and form dominant groups at the same time, leading to fish poisoning and even death. Eutrophication of water will also breed a large number of pathogenic microorganisms and infect fish. After the application of PSB, it can also inhibit the growth of other pathogenic bacteria, thus achieving the purpose of purifying water quality and making fish grow healthily. 2. Maintain the micro-ecological balance of water body.
There are all kinds of microorganisms in the water of aquaculture farms, some of which are beneficial and some are harmful; Some of them are called "conditional pathogenic microorganisms" in the intermediate state, that is, under normal circumstances, these microorganisms are not pathogenic. When the water quality is polluted and the immune function of fish decreases, they will multiply in large numbers and endanger fish.
Usually people use disinfectants to control it, but with the increase of application times, the drug resistance of pathogenic microorganisms increases accordingly. In order to achieve the effect of prevention and treatment, the dosage of each application has to be gradually increased, which not only increases the cost of medication, but also pollutes the water body, resulting in the decline of the quality of aquatic products and even inedible. Yichun patent center provides photosynthetic bacteria generator.
How to control the growth and reproduction of pathogenic microorganisms without drug resistance and water pollution? The answer is ready. Using photosynthetic bacteria to control fish diseases can completely overcome the shortcomings of disinfectants. It can not only degrade or remove harmful chemicals in water, including fish medicine, but also compete with pathogenic microorganisms for nutrition and space, so that they cannot grow and reproduce in large quantities, and at the same time, they do not produce drug resistance, so it is not easy to form pathogenic environmental conditions and fish are not easy to get sick. The principle of prevention and treatment of fish diseases is that prevention is more important than treatment. Only in the daily fishery production, maintaining the balance of micro-ecosystem in water, making beneficial microorganisms always have absolute advantages, and trying not to give pathogenic microorganisms a lot of opportunities to grow and reproduce, is one of the ways out for healthy aquaculture. If there is no effective prevention at ordinary times, it is inevitable to treat the symptoms, including the cost of fish medicine.
3. Cultivate Mayflies as bait. PSB is rich in cell nutrition, which is just a good bait for Mayflies. Practice has proved that the more PSB in water, the more vigorous the growth of ephemera, and the more obvious the effect of increasing the yield of fish eating ephemera.
4. As a feed additive, PSB's bacterial cells are rich in nutrition and contain a lot of physiologically active substances, which can be directly mixed into feed for feeding. PSB can not only increase nutrition and reduce feed coefficient, but also stimulate animal immune system, enhance digestion and disease resistance, and promote growth.
5. When indirectly oxygenated PSB grows and reproduces, oxygen is not needed or released. It indirectly increases oxygen by absorbing oxygen consumption factors in water. And this effect is also very obvious.
