Abstract:
Sewage-fed aquaculture is a popular practice in West Bengal as well as India. But the physicochemical parameters of the pond should be assessed before using it in fish cultivation. So, we conducted a study in a sewage-fed pond of Kolkata, West Bengal to evaluate ten physicochemical characteristics namely temperature, pH, total dissolved solids (TDS), conductivity, total hardness, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), phosphate phosphorus and nitrate nitrogen. The analysis showed that the physicochemical parameters of the pond water were moderate for cultural operation except for TDS (446.69mg/l) and the NO₃-N (0.80mg/l) and PO₄-P (0.21mg/l contents of the pond water were high. But final certification can only be provided after assessing the level of pollutants especially heavy metals.
