Attempt at Purification of Effluent and Sediment in Shrimp Aquaculture Ponds Using Mangrove Trees

Abstract

Water was circulated between shrimp and mangrove ponds to process effluent from shrimp aquaculture using mangrove trees at the Samut Songkhram Research Station, Kasetsart University, Thailand. Shrimp growth was faster in the ponds circulated with water from mangroves during the first 63 days of culture, before mass mortality occurred. Mass mortality of shrimp occurred after 63 days of culture. Though a load reduction effect to the environment was observed in the nitrogen and phosphorus budgets, this experiment was terminated prior to completion due to mass mortality. Further experiments on processing effluent with mangroves are needed.
