University Malaysia Sabah Hatchery (UMS Hatchery) is an important place for practice and study in aquaculture field in University Malaysia Sabah. UMS hatchery located near the coastal water at Sepanggar Bay and the water from this coastal is the source of seawater for this hatchery. This hatchery often faces the threat of severe water quality problem like low salinity, high concentration of turbidity, red tides. On other hand, hatchery activities maybe also contribute to pollutant The effects of hatchery discharging water on the adjacent water bodies over a crop cycle period were evaluated by studying the water quality of inlet and outlet of the hatchery. The characterization of the water consisted of the evaluation of the variation of 10 parameters along the inlet and outlet creeks and during the period of 10th January 2006 until 22nd February 2006. These parameters were pH, temperature, dissolved oxygen, turbidity, total dissolve solid nutrients (ammonium, nitrite, nitrate total nitrogen and total phosphorus). Average concentrations of total nitrogen (20.12 µg/I), total phosphorus (18.50 µg/I), nitrate (0.95 mg/I), nitrite (0.03 mg/I), ammonia (0.12 mg/I), dissolve oxygen (6.60 mg/I), temperature (29.88 °C) and turbidity (28.38 NTU) at the discharge site in the outlet were higher than in the inlet «19.75 mg/I, 18.05 mg/I, 0.71mg/I, 0.021, 5.88 mg/I, 28.00 °C and 19.98 NTU). The other parameters show that reading at inlet is higher than at outlet.
