Uneaten feed, organic waste and accumulated bottom sludge can steadily degrade water quality in aquaculture ponds, releasing toxic gases and raising the risk of disease. Vietnam Food Joint Stock Company (VNF) has developed Ecovital EM, a Bacillus spp. biological product that breaks down organic matter quickly, stabilises pond water and supports a more sustainable farming model. Used as a biological water treatment for aquaculture, Ecovital EM helps farmers keep water conditions steady while limiting waste build-up in the pond.
