Illegal shrimp hatcheries cause environmental damageVietNamNet Bridge - In many shrimp cultivation areas, farmers are not treating waste water from shrimp ponds, but are allowing untreated waste water to go directly into the environment. However, illegal shrimp farming in Chan May – Lang Co remains a ‘hot business’. The unprogrammed shrimp farming on sand in Kim Giao Thien hamlet of Hoai Hai commune has also caused serious consequences. As there is no standard waste water treatment system, the saltwater and waste water have been absorbed into the underground water. One hectare of shrimp farming area produces 8 tons of solid waste and tens of cubic meters of waste water.
