Intensive aquaculture is becoming more affordable leading to higher risks of environmental impacts. Gondwe et al. (2012) and Vezzulli et al. (2008) indicated that aquaculture is the major contributor to the increasing levels of organic waste and toxic compounds. 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).
