Without proper treatment, aquaculture waste would
potentially cause newly emerging diseases due to antibiotic resistance
and harmful algal bloom (Hegaret, 2008; Rubert, 2008).
Wastewater effluent from aquaculture industry contains nitrogenous
compounds (ammonia, nitrite and nitrate), phosphorus and
dissolved organic carbon which may lead to environmental
deterioration at high concentration (Ali et al., 2005).
