According to statistics from the Ministry of Animal Health (Ministry of Agriculture and Rural Development), the total damaged shrimp farming area in 2022 will be over 23.4 thousand hectares in 21 provinces and cities. This number increased by 15.5% compared to 2021. The area of intensive and semi-intensive shrimp farming suffered the most damage with more than 8,500 ha.
From the beginning of 2023 to date, over 1.6 thousand hectares of farmed shrimp have been damaged across the country. The total area of the detected disease is about 688 ha. The disease situation in farmed shrimp is particularly evident in some places in the Mekong Delta, such as: Ca Mau, Bac Lieu, Tra Vinh, Soc Trang. To learn more about the above problem, Ms. Bui Thi Huynh Hoa, director of Viet Duc Science Co., Ltd. on the current problem of prevention and control of shrimp diseases.
According to Ms. Hoa, the current weather pattern does not follow any rules, leading to a very high risk of large-scale disease outbreaks. People can lose everything if they don’t know how to proactively prevent them from happening in the first place. To prevent diseases in shrimp, Ms. Hoa said people should follow biosecurity guidelines. Farmers should prevent disease from the start.
“We support people with knowledge about prevention so that when they encounter a situation with diseased shrimp, they are not nervous and are not passive about prevention. For example, if you come across a case of shrimp with liver disease, how do you deal with it? How should intestinal diseases be treated? We will help you to find out the cause of the problem. “First of all, people need to know the cause in advance, and then develop a treatment method to reduce the damage,” said the director of Viet Duc Science Co., Ltd.
Discussing shrimp disease control solutions, Ms. Hoa shared that her company is fortunate to take over the scientific research of previous researchers, so Ms. Hoa advises farmers to choose breeding methods, science and microbiology.
According to Ms. Hoa, it will be more sustainable to protect nature and be in harmony with the environment. Firstly, shrimp farming must be preventive, for example by using microorganisms to inhibit harmful bacteria in shrimp ponds.
Secondly, it is advisable to remove unnecessary organic nutrients from farmers’ ponds.
The third is to create a suitable environmental buffering system for the growth of beneficial algae and beneficial organisms, remove toxic gases from the pond, and create a suitable environment for shrimp to grow.
Shrimp farming is associated with the aquatic environment and farmers often call it aquatic farming. Therefore protection of water bodies and creation of suitable buffer systems for beneficial algae.
Beneficial microorganisms and immediate removal of debris in the pond when the shrimp sheds the shell. Shrimp manure and excess feed should be cleaned up immediately to protect shrimp ponds.

According to the director of Viet Duc Science Co., Ltd, aquatic animal medicines are classified into many types. Antibiotics aren’t necessarily bad, but people need to know how to use them in order to administer the right and appropriate dose for the issues they are addressing.
“The daily feed dose must be appropriate, not causing residues and avoiding drug resistance, so close monitoring of the shrimp farming process is very important,” Ms. Hoa noted.
When talking about the situation of trading banned antibiotics in aquaculture, people still choose to use antibiotics of unknown origin. How does this affect companies that are active in this area? fisheries sector.
Ms Hoa quoted the words of Minister of Agriculture and Rural Development Le Minh Hoan: “In order to develop a resource industry, we need to focus on the ecosystem of this resource and how we can develop it sustainably.”
In relation to animal production, the use of breeding stock and the disposal of waste, everyone has to take responsibility. In particular, the responsibility lies with the manufacturers of aquatic veterinary medicinal products, the people and the administrative authorities.
According to Ms. Hoa, the Fisheries Act 2017 explicitly sets out the responsibilities, rights and duties of aquaculture farmers. Therefore, every farmer must make efforts to develop the aquaculture industry safely and sustainably.
