With the development of aquaculture in the direction of high density and intensification, it has brought considerable economic benefits to farmers and also caused a continuous deterioration of the aquaculture environment. This has led to an increase in the number of pathogenic microorganisms and an increase in the spread of disease, and the occurrence of disease has become increasingly serious. This has given rise to aquaculture Cause major losses. At present, the traditional method of disease control is the use of drug control. Although many diseases have been controlled accordingly, antibiotics can increase the resistance of pathogenic bacteria and cause double pollution, and there are residues in the organism, often for the aquaculture industry. And the human body has side effects. In order to promote the sustainable development of the aquaculture industry and ensure the quality and safety of aquaculture products, fishery microecological agents have emerged. Among them, photosynthetic bacteria are most widely used in pond aquaculture and do not produce secondary pollution. It can improve the water environment, inhibit the reproduction of pathogens, increase fish disease resistance, reduce morbidity, reduce drug expenditure, and promote fish growth. Increase fish production, improve aquaculture efficiency, and promote sustainable and healthy fishery development: one. Usage: 1 water spray. Suitable for use in improving water quality, preventing fish diseases, and cultivating excellent algae. Select sunny morning or afternoon, the proliferation of photosynthetic bacteria will be diluted with the pool water, the whole pool evenly spilled, the general amount: Seed pool: 150ml / L once every 5-10 days. Adult fish pond: 2ml/L after 5ml/L for the first time, or 5-8kg/mu for the first time, 3-5kg/mu in the future, once every 10-20 days. The number of photosynthetic bacteria is best studied according to the water quality. The water quality can be applied once every 15 days. The water quality is poor and the fertilizer should be applied every 7-10 days. Because the photosynthetic bacteria are fine in shape and small in specific gravity, if a direct method of aquaculture is adopted, the viable bacteria do not easily settle to the bottom of the pond, and the effect of the bottom environment cannot be improved. Therefore, it is recommended that when Quanchipite spills, try to combine it with zeolite powder mixture so that it can quickly settle the living bacteria to the bottom, and the zeolite can also play the role of adsorbing ammonia, or mix soil into the fish pond. 2 feed added. When using mixed baits as feed additive, spray the photosynthetic bacterial liquid that has been expanded well and mix it in the dry feed. If it is fed with a bait feeder, it can be mixed and then blown for a while and then fed for a period of time. Finish. Second, pay attention: 1 can not be mixed with disinfectants, do not use disinfectants within one week before and after use, or kill photosynthetic bacteria affect the use of effects. 2 Before use, the bacteria solution light for more than 10 hours, the use of good results, sunny water temperature above 20 °C use; rainy days do not use. 3 When the water is alkaline, the application effect is good. Use lime or caustic soda to adjust the pH to neutral or partial alkali. 4 The amount and continuity of use should be flexible, because photosynthetic bacteria can only play a role in the formation of dominant communities in the water. 5 Photosynthetic bacteria cannot be stored in metal containers. 6 When cultivating fry, sprinkle the whole pond 7 days before the seedlings enter the pond in order to facilitate the growth of plankton; photosynthetic bacteria broth combined with manure, the effect is obvious, and the increase in production efficiency is particularly significant. 7 If different water purification preparations are applied at the same time, care should be taken to ensure compatibility between the preparations. For example, nitrifying bacteria and photosynthetic bacteria are not suitable for stocking in the same pool at the same time, because the process of purifying the water mutually inhibits each other and may reduce the purification effect.
