- Flukes and Trichodina cause diseases mainly in fingerlings and parasitize mainly on gills, fins, scales, and bodies of fish (Figure 1: Flukes and Trichodina).

                          Figure 1: Flukes and Trichodina.


Figure 2: Signs of fish infection with parasites.

- Fish eat weakly, float a lot on the water surface in the morning.
- Bring pale fish, gill silk, congestion, mud, with many white pus spots, fish skin with wounds, red spots (Figure 2: Signs of fish infection with parasites).
- The disease develops a lot in fingerlings and fingerlings when weather conditions change suddenly, fish resistance is weak, especially in the rainy season and the pouring season of the year.


a. Preventive solutions:

- Farming moderate density and regularly checking fish: observing and checking on a microscope.
- Use VB-PRAZI_concentrated (1kg / 15-20 tons of fish) periodically to prevent parasites, especially during the pouring season.
- Periodically supplement BIO-X_pro + VB-SKY new (1kg/L/10-15 tons of fish) to enhance digestive support, liver function, kidney function 2 times/week. 

b. Treatment solutions
Case 1: Pure fish infected with parasites

+ Cut primers and treat DE AGA parasites, pay attention to use when standing water or surrounding raft for effective treatment.
+ 50-70% reduction of aquafeed and combined use of VB-PRAZI_concentrated + GATONIC pro, 2 consecutive days.
+ After the draw, use BIO-X_pro (1L / 15 tons of fish) to enhance the digestive microbiological support, liver function.

- Case 2: Fish is infected with hemorrhagic disease
+ Cut primers and use GLUMAX (1L / 5,000m3) to disinfect the environment.
+ Reduce aquafeed intake (50%) and combine treatment with VB-PRAZI_concentrated + GATONIC pro + VB-RIDO_01.
+ After that, use BIO-X pro + VB-SKY new (1kg or 1L / 15 tons of fish), to enhance the digestive microbiological support and liver function.

Fish when imported to the pond often lose a lot due to:

- Construction during transportation.

 Stress due to changing living environment.

- Easy to get bacteria and fungi to enter the body.

- Internal parasites disease on snakehead fish caused by hookworm, roundworm, tapeworm parasitizing in fish intestine.

Scientists have not identified the cause of the disease, but only diagnosed the following factors: (1) Fish nutritional imbalance; (2) the stocking density is too thick; (3) End-feeding for a long time continuously; (4) The pond water environment is polluted, there are many environmental toxins, heavy metal contamination and chemical residues; (5) Use antibiotic treatment continuously.

Chinese caterpillar fungus, also known as cordyceps, cordyceps, or cordyceps, is a precious oriental herb that is essentially a parasitic form of the Cordyceps Sinensis fungus (belonging to the Ascomycetes group) on the muscle. Deep body Hepialus Fabricius. The medicinal properties of cordyceps have been shown to be due to the Cordyceps Sinensis mushroom extracts.

REPLACE ANTI-BIRTHDAY FROM Hoang Lien (Coptis teeta Wall)

Currently, under the increasing requirements of export markets as well as consumers, the chemical residue in seafood products is being mentioned.

In addition, the incorrect use of antibiotics, treatment regimens, and the use of antibiotics for feeding in aquaculture cause the residues of resistance in the environment quite a lot, leading to more and more antibiotic resistance. fast and serious.

At the same time, the use of antibiotics also destroys most of the intestinal microflora. Adverse effects on aquatic animals affecting the development of aquatic animals.

Herbal antimicrobials are seen as an effective alternative to antibiotics.

Hoang Lien is known to be one of the top herbs for antibacterial, increasing immunity against pathogenic bacteria.

Common diseases of pangasius catfish farmed in Vietnam

Bacterial infections and ectoparasites leading causes of mortalities

The clinical signs of Edwardsiella ictaluri infection in pangasius are numerous white spots on the kidney, spleen and liver.

The freshwater catfish (Pangasius hypophthalmus) is an indigenous fish species in high demand from global consumers. The commercial culture of pangasius in Vietnam provides improved socioeconomic status for thousands of Vietnamese producers.

As in other developing aquaculture ventures, health problems that include disease outbreaks from parasites and bacteria have been encountered. For pangasius, the most important disease problems are caused by the bacteria (Edwardsiella ictaluri), (Aeromonas hydrophila), (A. sobria) and (A. caviae).

Protozoan parasites encountered include organisms of the genera (Microsporidium), (Myxobolus), (Henneguya), (Trypanosoma), (Ichthyonyctus), (Trichodina), (Balantidium) and (Epistylis), as well as IIchthyophthirius multifiliis). Several metazoan parasites and noninfectious problems have also been reported.

A new tool in the battle against decapod iridescent virus (DIV-1)

A new diagnostic tool that can detect a range of aquatic pathogens, including DIV-1, between two and four weeks before clinical signs are apparent to shrimp farmers, has recently been launched by Genics.

Genics' MultiPath technology is now being used in 23 countries and covers over 90 percent of all Australian shrimp / prawn producers

Dr Melony Sellars, CEO of the Australian company, talks to The Fish Site about shrimp pathogens, founding a startup and the wisdom of shrimp farmers.

Prevention of White Feces Syndrome, White Gut Disease and White Muscle Disease in Shrimp

Shrimp culture tends to now be developed intensively with upgraded technology for higher and successful production. On many occasions, shrimp culture is affected by various diseases and experienced in the loss of crop or reduced the production level by various reasons, writes Mr. Prakash Chandra Behera, India.

Intensive and semi-intensive aquafarming accompanies several disease problems often due to opportunistic pathogens as evident from general aquaculture. High stocking densities, high food inputs, and other organic loads stimulate the selection and proliferation of opportunistic pathogens like bacteria, viruses, fungi, protozoa, etc.
