Abstract

A study was conducted to compare the different shrimp farming methods in enhancing the water quality of shrimp grow-out ponds. Physical and chemical parameters of pond water were analyzed monthly throughout the culture cycle. Comparison of environmental parameters studied in extensive and semi- intensive prawn culture farms at Pancham Aquaculture Farms Ltd (PAFL), revealed that levels of temperature, salinity, pH, total alkalinity, levels were approximately the same or with minor differences. On the other hand, concentrations of Free Carbon Dioxide(CO2), Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Ammonia, Total Suspended Solid (TSS), Secchi disk, Total Nitrogen (TN), Total Phosphorus (TP), N /P ratio and Chlorophyll-a were dissimilar. The difference may be atributed to stocking density and feed input.
