The journey of shrimp farming is paved with relentless challenges—from disease outbreaks and high production costs to plummeting shrimp prices. Facing these harsh realities, farmers often find themselves struggling constantly and carrying heavy anxieties over the success of every single crop.
Standing side-by-side with shrimp farmers has always been the core mission of Dong A Chemical. We strive to help farmers optimize operational costs in pond water treatment using Pearl Chlorine 70%—the very first international-quality calcium hypochlorite successfully manufactured right here in Vietnam.

Dong A accompanies shrimp farmers with high-quality Pearl Chlor.
Challenges in Pond Water Treatment for Shrimp Farmers
Water-exchange farming is a long-standing and widely adopted model in Vietnam, particularly among farmers in the Mekong Delta. Sourcing and introducing clean intake water to replace old pond water plays a critical role in determining the success of the entire crop.

Water exchange and intake water treatment pose significant challenges for shrimp farming households.
Water exchange or treatment is implemented to resolve critical issues arising within the ponds, such as toxic gases, pond liner slime, suspended solids, and disease outbreaks. However, inadequate treatment of exchange water can facilitate the intrusion of external pathogens into the pond system. Therefore, maintaining strict water quality control is vital for farmers to achieve optimal yields.

Today, growing pollution in natural water bodies has made sourcing high-quality intake water far more challenging. Shrimp farmers must spend significantly more on water treatment and dedicate extensive land areas to treatment ponds, consequently reducing the actual farming acreage.
The Cost-Optimizing Solution for Shrimp Farming
With water scarcity and polluted water sources, farmers are virtually sitting on pins and needles. Without prompt and effective water treatment, severe economic losses are inevitable, heavily impacting the livelihoods of farming families.
