How to Maintain Water Quality for Shrimp Farming


Description: water quality for shrimp farming determines the shrimps’ health. Here are important factors that determine water quality.

 

 

Shrimp farming requires ideal water composition to keep shrimps healthy. Farmers must check and maintain water quality for shrimp farming continuously. There are several factors to check and maintain, such as salinity, oxygen level, salinity, acidity, alkalinity, sulfate and nitrate levels, and the presence of microorganisms.

Here are several factors to consider when maintaining shrimp farm water quality.

 

1. Temperature

Shrimps love warm temperature, which is why shrimp farms are common in warm regions. The ideal temperature is 57 to 84-degree Fahrenheit (14 to 29 degree Celsius). Shrimp farmers in colder regions (or months) can use a solar heater, electric heater, or greenhouse panels.

 

2. pH Level

Ideal pH level in the water for shrimp farming is between 6.5 and 9.5. Farmers should maintain this pH level by preventing algae from growing in the pond, which can increase alkalinity. If the water is too acidic, farmers can add limestone to increase the pH and reduce acidity.

 

3. Biosecurity

Biosecurity means keeping the shrimps safe from predators. Common threats include birds, crabs, reptiles, and fish. They not only eat the shrimps but also spread bacteria that destroy the harvests. Farmers can install fences, dry ponds before filing them with water, and apply saponin, calcium carbide, ammonium sulphate, or tobacco dust to the water.

 

4. Nitrogen and Ammonia Levels

Nitrogen and ammonia levels determine the water’s toxicity level. Farmers must balance the level of nitrogen and ammonia by maintaining good drainage system. Good circulation is also important to keep the toxicity level low.

 

5. Oxygen Level

Farmers need to keep proper oxygen level in ponds to make the shrimps healthy. There are several tools that can be used to test the oxygen level, such as chemical or electronic testing kits. Farmers must aerate the ponds using air compressors, agitators, fountains, or blowers. Fountains are popular among farmers who also need decorative elements in their ponds.

Keeping good water quality for shrimp farming is important. Farmers must make sure that all these elements are applied properly before growing the shrimps.
