Abstract:
The water quality study was carried out as part of an environmental
impact assessment of tiger prawn farms in the coastal areas of Bagan Tengkorak in the
State of Selangor, Malaysia. The water quality measurement that was carried out
includes twenty over physical and chemical parameters including heavy metals. The
measurements were carried out at six (6) ponds (B5, B6, B7, B8, B9, BIO) called Group
B ponds at both juvenile and adult stages. The results of water quality study showed that
there was no significant variation between the ponds for parameters such as temperature
and pH. However, a significant variation was recorded between the ponds for salinity,
BOD, suspended solids, turbidity, dissolved solids, ammoniacal nitrogen, calcium and
magnesium. The temperature, pH and N03 were slightly and consistently lower during
the adult stage as compared to juvenile stage. However, salinity, suspended solids,
turbidity and BOD were consistently and significantly higher in adult stage as compared
with juvenile stage. Overall, there are some differences in water quality between
juvenile and adult stages in the tiger prawn life cycle in Bagan Tengkorak shrimp
culture ponds of Malaysia
