What to do during prolonged rainy weather in shrimp farming

The prolonged rainy season poses many risks to shrimp ponds: pH drops, algal die-off occurs, toxic gases increase, and shrimp are more susceptible to environmental stress, slow growth, body curvature, and muscle opacity. Farmers need to manage their ponds carefully, maintain shrimp health, and apply timely treatment solutions. The article below will help farmers find effective solutions.

1. How does rain affect shrimp ponds?

During the rainy season, especially when rainfall is prolonged and continuous, the shrimp pond environment changes rapidly and becomes difficult to control. Rainwater dilutes the pond, reducing salinity, pH, and alkalinity, causing significant fluctuations in the pond’s physico-chemical parameters. When the surface water is diluted, differences arise between the bottom and surface layers, leading to water stratification, which easily results in oxygen deficiency at the pond bottom.

Heavy rain can also cause algal die-off (algal crash), changing the pond water color. The decomposition of dead algae generates toxic gases such as H₂S, NH₃, and NO₂. In addition, during periods of heavy rainfall, soil, fallen leaves, and plant debris are washed into the pond bottom. If this accumulated organic matter is not treated in time, it further destabilizes the environment and creates favorable conditions for the development of bacteria, fungi, and parasites.

Without timely intervention measures, prolonged rainfall will destabilize the culture pond, making management much more difficult and increasing the risk of disease outbreaks in farmed shrimp.

2. Solutions for managing shrimp pond environments during the rainy season

To stabilize the shrimp pond environment during the rainy season, farmers need to proactively monitor and make timely adjustments:

• Cover pond dikes with tarpaulins to prevent rainwater from directly diluting pond water.
• After rainfall, promptly check and balance pH, alkalinity, and salinity.
• Use CANXI AO or ALKALITE to increase alkalinity and stabilize pH.
• Increase paddlewheel aerators and aeration to prevent water stratification and ensure sufficient dissolved oxygen.
• Supplement minerals and vitamins to rebalance essential minerals in the pond.

In particular, it is recommended to use AQUA VITAL – the immunity booster. This product helps shrimp quickly recover from environmental stress after rain, enhances overall health, and stabilizes water conditions. When used regularly, AQUA VITAL also supports improved water quality and minimizes the risk of body curvature and muscle opacity diseases in farmed shrimp.

3. Shrimp health care solutions during the rainy season

In addition to environmental management, direct shrimp health care is also extremely important during the rainy season:

• Regularly monitor shrimp behavior and physical condition, including external appearance, coloration, hepatopancreas and gut condition, and feed intake.
• Feed shrimp at the correct dosage, avoiding overfeeding that can cause pond pollution.
• Combine the use of ANTI-ZYME intestinal probiotics to improve nutrient absorption and help reduce intestinal diseases.
• Limit the indiscriminate use of antibiotics and replace them with safe, biosecure products.
• Supplement nutrition rich in minerals, vitamins, and amino acids to enhance shrimp immunity.

An effective solution is RED WEIGHT – a comprehensive nutritional product from My Binh Company. RED WEIGHT helps shrimp gain weight rapidly, develop firm flesh, and show clearly enlarged intestines after just 2–3 days of use. At the same time, it supports the prevention of body curvature and muscle opacity, improves coloration, and increases overall harvest productivity.

Prolonged rainfall always poses many risks for shrimp farmers, from unstable water conditions to weakened shrimp health. Farmers need to closely manage their ponds and supplement minerals, vitamins, and comprehensive nutrition to protect their shrimp stocks during the rainy season.
