Samples of aquaculture wastewater were collected from the aquaculture rearing tank of African Catfish, (C. gariepinus) located in the freshwater hatchery of Universiti Malaysia Terengganu,Malaysia.
African Catfish was selected due to its high metabolic
waste production and its ability to tolerate very low water quality.
During treatment period, the fish was fed daily with the same type
of feed formulation at 2% of body weight to ensure the constant
release of phosphorus and nitrogen waste. As the pond was placed
in a greenhouse, the water temperature slightly varied within the
range of 28 ± 5 C over diurnal changes. C. gariepinus released
nutrients to the surrounding water as dissolved inorganic nutrients
through metabolic excretion, particulate organic nutrients through
defaecation and dissolved organic through resuspension from the
particulate fractions (Olsen et al., 2012).
