Shrimp farmers in Vietnam face weather and disease risks

Shrimp farmers in Vietnam are facing significant challenges due to erratic weather patterns and disease risks. Heavy rainfall in September caused sudden drops in water salinity, in some cases falling from 12‰ to nearly 0‰. These fluctuations, followed by prolonged heatwaves, have destabilized pond environments, leading to toxic accumulation and poor shrimp growth.

To mitigate losses, some small-scale farmers in the Ha Lam area have opted for early harvesting, accepting lower profits to avoid the high risks of continued cultivation. Meanwhile, Long Van Seafood Joint Stock Company, which manages 20 hectares of high-tech shrimp farming, is focusing on stabilizing pond environments through increased aeration and the supplementation of minerals and vitamins to boost shrimp resistance.

Experts also warn of potential White Spot Syndrome Virus (WSSV) outbreaks, characterized by white spots on shells, reduced feeding, and lethargy. Recommended management includes strict water quality control, monitoring dissolved oxygen and pH, and avoiding the unauthorized use of antibiotics to treat viral infections.
