The Role of Lactic Acid Probiotics in Aquaculture
The Role of Lactic Acid Probiotics in Aquaculture
1、 Adjusting Water Quality and Improving Aquaculture Environment
Decomposing Organic Matter: Lactic Acid Probiotics can decompose organic waste such as residual feed and feces in water bodies, reduce the concentration of toxic substances such as ammonia nitrogen and nitrite, and reduce water pollution.
Stablizing pH Value: By secreting acidic metabolites, the pH value of the water is reduced, the reproduction of blue-green algae, harmful bacteria, and pathogenic microorganisms is inhibited, and the transparency of the water is improved.
Fertilization and Oxygenation: Promote algae growth, indirectly increase dissolved oxygen in water, and maintain ecological balance.
2、 Promote Nutrient Absorption and Growth Performance
Enhancing Digestive Ability: Organic acids and enzymes (such as proteases and cellulases) produced by the metabolism of Lactic Acid Probiotics can improve feed utilization and promote the absorption of minerals such as calcium and phosphorus, as well as proteins.
Luring Effect: Lactic Acid Probiotics stimulates the appetite of farmed animals, accelerates growth rate, and increases weight gain rate.
3、 Enhancing Immunity and Disease Prevention and Control
Inhibition of Pathogenic Bacteria: By competitively repelling and secreting antibacterial substances (such as lactic acid), the reproduction of harmful bacteria such as Nocardia and Escherichia coli is inhibited, maintaining the microecological balance of the gut and aquaculture water bodies.
Immune Regulation: Lactic Acid Probiotics can activate the immune system, enhance the disease resistance of fish and shrimp, and reduce the incidence of bacterial diseases (such as Vibrio infection).
4、 Other Synergistic Effects
Adsorption of Toxins: Reduce the harm of harmful substances such as mycotoxins to farmed animals.
Joint Application: Alternating with Bacillus subtilis, Lactic Acid Probiotics can synergistically reduce ammonia nitrogen sub salt and improve water quality control effect.
Precautions for Use
Activation Method: Use 40-50 ℃ warm water and glucose (1:1 ratio) to seal and ferment, avoiding oxygenation.
Timing of Use: It is recommended to sprinkle after dawn to quickly establish an ecosystem through the synergistic effect of bacteria and algae.
Control Dosage: Excessive dosage of Lactic Acid Probiotics may cause water acidification, and the dosage should be adjusted according to the pH value of the pond (recommended ≤ 8.2).
The above functions of Lactic Acid Probiotics integrate multidimensional functions such as water quality regulation, nutrient enhancement, disease prevention and control, and ecological synergy, and are important microbial regulation methods in aquaculture.
