Figure 2: Daily ortho-P and total P waste (mg/kg fish) of Australian catfish fed with CM diets supplemented with different combination of nutrients (CM45: no nutrient supplement; CMF: only phytase 1000 FTU/kg; CMFA: phytase and crystal lysine & methionine; CMPA: AAs and inorganic P; CMAA: only lysine and methionine, CMP: inorganic P only), conducted at 24oC (mean ± S.E., n=3 replicate tanks/treatment). In the same data series (*) indicates significant difference from the control and (**) indicates significant difference from fish fed CM45 diet (P < 0.05).
