Water quality parameters of coastal shrimp farms from southwest and southeast regions of Bangladesh
The impacts of shrimp farming on water quality and effluent loading of shrimp farms insouthwest (Khulna) and southeast (Cox's Bazar) regions of Bangladesh was investigatedduring March-August and August-October season, respectively. Water salinity fluctuatedfrom 3.0 to 15.0 ppt in the southwest, whereas it was between 2.5 to 20.0 ppt. in southeastregion. Total ammonia nitrogen as recorded in most farms of Cox's Bazar region washigher (0. 1160.438 mg/L) than the recommended level of shrimp farming. Mean valuesof total ammonia nitrogen and total nitrogen at the outlet of shrimp farms were higherthan those of inlet in both regions. Mean values of phosphate phosphorus and totalphosphorus at outlet were lower than inlet except in harvest time of Penaeus monodon.Total suspended solids were deposited on the bottom of shrimp farms in both regions,which resulted in higher concentration in inlets than outlets in both regions.
