EDTA in Shrimp Farming
What is EDTA?
EDTA stands for EthyleneDiamineTetraacetic Acid. This is a strong organic acid (more than 1,000 times stronger than acetic acid). Its salts are usually in the form of white crystals or powder, non-volatile, and highly soluble in water.
Uses of EDTA
- In aquaculture: EDTA is used to neutralize acidity, remove heavy metals, reduce water viscosity and scum in ponds. It also breaks down toxins from chemical use and reduces pH in shrimp ponds.
- EDTA is one of the ingredients found in cosmetic products like shampoos, hair dyes, etc.
- In laboratories: EDTA is used to remove metal ions.
- In pharmaceuticals: It acts as an antioxidant to prevent free radicals from damaging blood vessels and reducing atherosclerosis, although it has not yet been applied practically.
- In industry: EDTA isolates metal ions that alter the color of dye products.
- In agriculture: EDTA is used to create chelates to prevent the precipitation of heavy metals in the water environment.
Dosage of EDTA in Shrimp Farming
- For water treatment in hatcheries, the commonly applied dosage is 5-10 ppm.
- For water treatment in shrimp farming, especially in areas with low salinity and acidic soil, when water levels in ponds reach about 0.8-1 m, if the alkalinity is low and the water has a light yellow color, EDTA can be used at a dosage of 2-5 kg per 1,000 m²
