When Does Coin Fungus Usually Appear?

Coin fungus typically develops at the bottom and edges of shrimp ponds, appearing in various forms such as scales, branches, fiber bundles, or dog feet. The main causes leading to the development of coin fungus include:

• Excess organic matter, leftover food, and shrimp waste along with the presence of many other microorganisms.

• Lack of oxygen and the presence of toxic gases such as ammonia, nitrite, nitrate, sulfide, methane, etc.

• Low water temperature, unstable pH levels, and irregular salinity fluctuations.

• Bacterial contamination from bacteria, spores, parasites, and protozoa that cause diseases in shrimp.

• Algal collapse in the pond and high salinity in the farming area.

Identification Signs:

• Diverse Colors: Coin fungus can have green, white, yellow, or brown colors, depending on the type of algae symbiotic with the fungus.

• Unpleasant Odor: This fungus emits a very unpleasant fishy smell, causing shrimp to stop eating, become weak, slow-growing, and prone to diseases.

• Causes Diseases in Shrimp: Coin fungus can lead to many shrimp diseases such as intestinal disease, soft shell disease, stunted growth, liver atrophy, white feces disease, and loose bowel disease.

• Disease-causing Organisms: Coin fungus can create clusters of fungus, becoming a hiding place for many disease-causing organisms for shrimp, including Vibrio bacteria, spores, parasites, and protozoa.

Current Solutions Being Applied

Some shrimp farmers often use mechanical measures such as scrubbing and cleaning to remove coin fungus. However, these methods are not only ineffective in killing the fungus but also create conditions for the spores to spread more vigorously and quickly. Furthermore, when the fungi are scrubbed off, they can produce toxins that negatively affect the health of shrimp.

Using chemicals to treat coin fungus usually brings temporary effects, but the fungus can reappear after a short period. If chemicals are used improperly or excessively, they can harm the natural environment in the pond, adversely affecting the ecosystem and water quality. Therefore, finding more sustainable and safer solutions is necessary to effectively manage and control coin fungus.

Measures Provided by ECO 

Given the current situation, ECO International Co., Ltd. has introduced a safer and more effective solution for shrimp farmers. Coin fungus causes significant damage to shrimp ponds and is very difficult to treat once infected. Early detection of the fungus in the pond is key to managing and treating it gently and effectively.

The treatment method will vary depending on whether the pond has shrimp or not. ECO encourages farmers to use ECO LEAVEN yeast products in appropriate doses to prevent coin fungus from the outset, to avoid the situation where the shrimp pond gets infected and causes damage to the shrimp during the farming process.

ECO LEAVEN is a unique combination of yeast, antibacterial and antifungal agents, along with other disease-fighting agents in the digestive system of shrimp and fish, as well as the water environment. This product also contains concentrated enzymes that help quickly decompose excess organic matter in the water, creating a healthy living environment for shrimp and fish.

With ECO LEAVEN, shrimp farmers can confidently manage and control coin fungus, protect the health of shrimp, and improve economic efficiency. ECO International Co., Ltd. is committed to providing sustainable and safe solutions for the shrimp farming industry, contributing to the sustainable development of the aquaculture industry.
