Anti-stress Drugs for Aquaculture

stress refers to the adaptive and protective response to changes in external environmental conditions. Changes in external environmental conditions are called stressors. Fish, shrimp, crab and other aquatic animals, in the process of intensive artificial breeding, inevitably face more and more stimulating effects that lead to stress response factors. When stress occurs, what are the commonly used anti-stress drugs? What are the effects of anti-stress drugs?

?

1. Carbohydrate: glucose, active polysaccharide, chitosan, etc;

2. Vitamins: VC, VB, VE, etc;

3. Amino acids: lysine, methionine, tryptophan, taurine, glutamine, etc;

4. Electrolyte mineral elements: sodium bicarbonate, sodium chloride, potassium chloride, ammonium chloride, organic magnesium, selenium, zinc and chromium;

5. Organic acids: citric acid, malic acid, humic acid, betaine, etc;

6. Microecological preparations: lactic acid bacteria, Bacillus, etc.

anti-stress drugs?

1. Regulate the nervous system, stabilize and calm, and reduce stress sensitivity (it is worth paying attention to taurine and & gamma;-Aminobutyric acid, which can inhibit the activity of nervous system neurons, has the effects of stability, sedation, and anticonvulsion, so it can reduce the body's response to stress and play a role in preventing stress);

2. Antioxidation, scavenging reactive oxygen species, and regulating free radical metabolism disorders caused by stress (are the main ways for many anti-stress agents to function, among which taurine, a-lipoic acid, astaxanthin, vitamin C, immune polysaccharide, etc. are worthy of attention);

3. Regulate the metabolism of various substances in the body and regulate the abnormal metabolism caused by stress.

the above is "what are the commonly used anti-stress drugs? What are the effects of anti-stress drugs?". Prevention of fish and shrimp stress is a way to improve survival rate and success rate. Usually management should enhance fish immunity, use corresponding drugs to relieve stress response, improve immunity and improve survival rate.
