Microecological preparations refer to biological living bacterial preparations for animals that are made of special beneficial microorganisms that have been cultivated, rejuvenated, fermented, embedded, and dried under the guidance of microecological theory. It plays an important role in the establishment of a good micro-ecological environment of waters and can create conditions for the production of pollution-free shrimps and crabs. First, the role of micro ecological agents 1. Maintaining the balance of microecological systems in the shrimp and crab ecosystems The shrimps and crabs in the intestine have a certain number of microbial populations and are in a dynamic equilibrium. When the organism is affected by various adverse factors such as feed changes, environmental temperature changes and long-term use of antibiotics, etc. The impact of this balance will be lost, the original dominant population changes, resulting in reduced body resistance of shrimp and crab. At this time, microecological preparations are used to allow beneficial microorganisms to proliferate in the intestine, produce metabolic products and antibiotic-like substances, reduce intestinal pH, and compete with harmful microorganisms for nutrients, thereby preventing the generation and reproduction of pathogenic microorganisms. In order to maintain and restore the balance of the intestinal micro-ecological system. 2. Synthetic enzymes and vitamins Some microecological preparations can produce various digestive enzymes in the shrimp and crab body and synthesize various vitamins, amino acids, growth factors, etc., secrete active substances, participate in energy and vitamin metabolism, and promote the utilization of shrimp and crab feed. Some enzymes in the intestine of shrimps and crabs contain less or even no synthesis. The beneficial microorganisms that produce these enzymes play an important role in ensuring the health of shrimps and crabs. 3. Antagonism and protection Some beneficial microorganisms reproduce rapidly in the intestines of shrimps and crabs, and they can compete with pathogenic microorganisms for the settlement sites in the intestine, inhibit the attachment of pathogenic microorganisms to the intestinal cell wall, and compete with the pathogenic microorganisms for the antagonistic action, thereby protecting the intestinal micro-ecosystem. Balance. 4. Enhance the body immunity Some beneficial microorganisms can accelerate the development of the body's immune organs, T. B. The number of lymphocytes increased, thereby improving the humoral and cellular immunity levels of shrimp and crab. 5. The biological microbes in the intestine of shrimps and crabs are mainly anaerobic microorganisms. When some beneficial aerobic microorganisms enter the digestive tract in a spore state, they rapidly proliferate and consume a large amount of oxygen in the intestine, which causes the concentration of oxygen in the intestines. The decline will contribute to the growth of anaerobic microorganisms and will not be conducive to the growth of aerobic pathogenic microorganisms. At the same time, the normal microecological balance in the body will be restored to prevent disease and promote growth. 6. Reducing the production of harmful substances When the activities of harmful microorganisms such as E. coli in the intestine of shrimps and crabs increase, the protein will be converted into ammonia, amines and other harmful substances. Because the microecological agents can significantly reduce the number of harmful microorganisms such as E. coli and Salmonella in the intestine, Reduce the excessive production of ammonia and other spoilage substances and reduce the amount of fecal odor. In addition, beneficial microorganisms can use excessive organic matter in the aquatic environment to synthesize bacterial substances and reduce the content of harmful substances such as ammonia nitrogen, nitrous acid nitrogen, and hydrogen sulfide in the environment and purify the aquaculture water environment. Second, the characteristics of micro-ecological agents and strains Since the 1970s, microecological agents as a possible alternative to antibiotics have been seriously valued. The beneficial microbial strains that have been approved for use by the Ministry of Agriculture of China include six major microorganisms such as Bacillus, Lactobacillus, Streptococcus faecalis, yeast, Bdellovibrio and Bacteroides fragilis. 1. Features of Microecological Agents In general, the species used for the microecological preparations used as feed additives should meet the following conditions: (1) No pathogenic, non-toxic side effects, no hybrid species with pathogenic microorganisms; (2) Most Good from the normal flora of the animal itself, in order to maximize its probiotic function; (3) Rapid propagation in vitro, with a strong competitive advantage; (4) Inorganic acids, organic acids and low pH Bile acid survives and colonizes the intestine; (5) Produces inhibitors of enteric pathogenic bacteria such as lactic acid, hydrogen peroxide, etc.; (6) is easy to industrially produce, has high survival rate after processing, and is stable at room temperature after mixed feed Good sex. The species used for the microecological preparations used directly in aquaculture waters to improve the ecological environment of the aquatic environment and prevent diseases in aquatic animals do not require the normal flora of the intestine, but must be natural microorganisms in the natural aquatic environment, and preferably Advantageous populations, such as photosynthetic bacteria, nitrifying bacteria, etc. 2. Common microbial species and characteristics of microecological preparations (1) There are many kinds of lactic acid bacteria, anaerobic or facultative anaerobic growth, and they can still survive at pH 3.0-4.5 acidic conditions; they can decompose carbohydrates, and the main metabolite is lactic acid, which can increase Intestinal acidity, which inhibits the growth of anaerobic pathogens that are not resistant to acids in the intestine. Lactic acid bacteria can produce aminooxidases and enzymes that decompose sulfides. It can completely oxidize the odorous source—the cerium compound—without poison, odor, and pollution. The substance can also synthesize short-chain fatty acids and B-vitamins, neutralize toxic products, inhibit the synthesis of ammonia and amines, and enhance immunity. The normal lactic acid bacteria in the intestine of aquatic animals include Lactobacillus, Streptococcus, and Lecithin citrulline. These bacteria can produce a special substance that can effectively inhibit the growth of E. coli and Salmonella. (2) Bacillus is a non-pathogenic bacterium in the aerobic bacillus, sporadically present in the microbial community of the animal's intestine in the form of endospores, and is resistant to alkali, heat and crushing in the acidic environment of the intestine. With a high degree of stability, the pH and ammonia concentration of the jejunum can be reduced, and the amount of propionic acid and acetic acid can be increased. Bacillus subtilis and Bacillus licheniformis can produce more active proteases and amylases. At present, Bacillus licheniformis, Bacillus subtilis, Bacillus cereus, Toyobacterium and the like are mainly used. (3) Yeast is able to effectively improve the structure of the gastrointestinal environment and flora by multiplying the bacteria in the body, promoting the reproduction and vigor of the beneficial bacteria such as lactic acid bacteria and cellulosic bacteria, and strengthening the nutrition of whole gastrointestinal feed. The decomposition, synthesis, absorption and utilization of the food, thereby increasing food intake, improving feed utilization and production performance, and participating in the surviving competition of pathogenic microflora, effectively inhibiting the proliferation of pathogenic microorganisms, and yeast can also provide Rich in vitamins and proteins. At the same time, it is also a nutrient source for beneficial bacteria such as Bifidobacterium and Lactobacillus, which can promote their large-scale reproduction and promote and protect intestinal health. The yeast currently used is isolated from the body surface of fish. (4) Arctic plays a dual role in the culture of fish larvae: harmful and beneficial. Vibrio spp. isolated from scallops is a beneficial bacterium that inhibits Vibrio anguillarum. (5) Photosynthetic bacteria are a kind of heterotrophic microorganisms with photosynthetic capacity. They mainly use small-molecule organic compounds to synthesize various nutrients needed for their own growth and reproduction. It is rich in protein, B vitamins, coenzyme Q antiviral activity virus factors and other biologically active substances, carotenoid pigments, tomato red pigments and other natural pigments with antioxidative effects. (6) Microcapsule probiotics Water purification complex bacteria are bacteria, spores, lactic acid bacteria, yeast, nitrosated bacteria, denitrifying bacteria and other beneficial microbial strains that will be isolated from the natural world, and they are domesticated and rejuvenated. Monoclonal technology and liquid or solid state fermentation culture, adding retention agent, forming a solid state by vacuum condensation at low temperature, or spraying a curing agent to form a microcapsule, and finally compounding micro-encapsulated compound micro-ecological preparation (abbreviated as bacteria). Complex bacteria can also be used as feed additives for shrimps and crabs. Third, the use of microbial agents use microbial use of high-tech means, production and application of micro-ecological agents to quickly and thoroughly degrade the harmful substances in shrimp and crab aquaculture, inhibit the growth of harmful algae, fungi, eliminating the breeding of pathogenic microbial factors, Maintain the microecological balance of the water, and at the same time, add the microecological preparations to the shrimp and crab diet to effectively regulate the balance of microecological flora in the intestine of shrimps and crabs, enhance the body's immune function, and increase the utilization of shrimp and crab for feed and viruses and bacteria. The disease-resistant ability of sexual diseases replaces the dependence on chemical disinfectants and antibiotics during shrimp farming. This undoubtedly found a green road that cherished water and life, comprehensively restored the water environment, developed healthy breeding, produced pollution-free shrimps and crabs, and realized healthy consumption.
