摘要

Prawn culture has attracted many investors because of its lucrative market possibilities locally and abroad. Efforts are being made to obtain higher production of commercially important species through aquaculture. This can be obtained by sustaining and maintaining stable and good quality of water. Even though the culture practices are carried out in areas devoid of pollutants, the inputs used in the culture system may contribute pollutants resulting in poor quality of water. Since many of the traditional culture farms are situated in the vicinity of industrial, muncipal and esturine areas the possibility of contamination of the water is apparent.
