1. Organic acids alleviate the toxicity of heavy metals such as Pb and CD

Organic acids enter the breeding environment in the form of water sprinkling, and alleviate the toxicity of heavy metals by adsorbing, oxidizing or complexing heavy metals such as Pb, CD, Cu and Zn. In a certain range, with the increase of mass molar concentration, the detoxification effect is better. In addition to degrading heavy metals to a certain extent, organic acids can also increase oxygen in water and improve the anorexia of Pelteobagrus fulvidraco.

In addition, organic acids can also convert molecular ammonia in aquaculture wastewater into NH4 +, and then combine with ammonia ions to form stable ammonium salts to reduce the toxicity of toxic ammonia in water.

2. Promote digestion, enhance resistance and anti stress effects

Organic acids promote the digestion of aquatic animals by affecting metabolic activities and improving enzyme activity. Organic acids can improve the activities of mitochondrial adenylate cyclase and intragastric enzymes, which is conducive to the production of energy and the decomposition of macromolecular substances such as fat and protein, and promote the absorption and utilization of nutrients; It is also involved in amino acid conversion. Under the stimulation of stressors, the body can synthesize ATP and produce anti stress effect.

Organic acids can promote the growth and reproduction of aquatic animals and reduce the diseases of aquatic animals caused by bacterial infection. Adding organic acid salt or its compound in feed can improve the immune index and disease resistance of shrimp and improve the nutritional value of animals. Organic acids can promote the reproduction of beneficial bacteria (such as bifidobacteria, lactic acid bacteria, etc.) in the intestinal tract of aquatic animals, inhibit the reproduction of harmful bacteria, change the structure of intestinal flora to a good side, promote the absorption of vitamins, calcium, etc., and improve the disease resistance and resistance of aquatic animals.

 

3. Promote food intake, improve digestibility and weight gain

Organic acids can promote the absorption of food by aquatic animals, improve the utilization rate of protein, and then improve the output value and quality of aquatic products. Potassium diformate, as an organic acid preparation, can enhance the activity of pepsin and trypsin, strengthen the metabolic activity, increase the digestion efficiency of aquatic animals to feed and promote growth by improving the acidity of feed.

4. Addition period of organic acids

The effect of adding organic acids in different growth stages of aquatic animals is different. The growth promoting effect is better in its young stage; In adulthood, it plays an obvious role in other aspects, such as anti immune stress, improving intestinal environment and so on.

With the development of aquaculture, the growth promoting effect of organic acids on aquatic animals is becoming more and more obvious.
