Intensification has become common practices in many whiteleg shrimp (L. vannamei) producing countries, and farming systems are evolving very fast from very simple systems to complicated ones which can be equipped with sophisticated water treatment, water quality auto-monitoring system, auto feeders ect… But the success is still limited. In our study, it clearly demonstrated that an increase of stocking density of shrimps with improper water treatment method can quickly deteriorate water quality and consequently lead to very high mortality and destroy the production (Fig. 1). To maintain water quality, shrimp farmers start increasing water exchange. In some cases, water exchange rate can exceed 10 m3 of water per 1 kg of shrimps after 90 days of culture. Increasing water exchange do not only increase production cost but increase the risk of pathogen outbreak and ruin ambient environment. This presentation will introduce an innovative solution developed by ADM which can help to reduce water exchange, increase water use efficiency and minimize production cost.
