What is the reason of red beard and red tail of Penaeus vannamei?

Rainy weather, adding water, algae become water, ammonia nitrogen, sub-salt, high PH, algae death, high temperature and strong light, etc. , will cause stress of prawns, resulting in the phenomenon of red beard and red tail. You can use "pressure spirit" per bottle /3 μm, and serious cases can be treated with "pressure spirit+good health".

2. Hypoxia

When prawns are in hypoxia, the phenomenon of red beard will also appear. In the anoxic state of shrimp ponds, firstly, consider whether rotifers or other protozoa exist in large quantities, which leads to the anoxic state of shrimp. Therefore, it is necessary to deal with the dissolved oxygen problem in the pond first, so as to alleviate the phenomenon of red beard of shrimp.

3. Virus

Red body disease of prawn will cause the whole body of prawn to be red, the jejunum and gastrointestinal tract to be red, and the tail fan of prawn whiskers will be particularly red. Viral diseases are difficult to treat, but prevention is still the main thing.

4. Vibrio infection

When the vibrio in the pond exceeds the standard, especially since June, the temperature rises and vibrio proliferates. If Vibrio is not detected in time to prevent it, it will easily lead to the phenomenon of red beard and red tail in Vibrio shrimp infection. It can be treated with "tetramethylphenolate" per bottle /3 μm, and in severe cases, it can be treated with "tetramethylphenolate+stress spirit".

5, water quality, sediment deterioration

The deterioration of water quality and sediment will also lead to red beard and red tail on prawns, so it is necessary to use "Bishui Jiedu 'an" or "fermentation bag" regularly to adjust the water quality balance and stabilize the water quality.
