Abstract

The work aimed to evaluate the requirement of total phosphorus (Pt) for Nile tilapia. 125 fingerlings with average initial weight and length of 0.95 ± 0.11 g and 3.81 ± 0.18 cm, respectively, were used. An entirely randomized design was used with five treatments (0.4; 0.6; 0.8; 1.0; and 1.2% of Pt in the ration) and five replications. The final weight (FW), final length (FL), food conversion (FC) and survival (SU) were evaluated. The best FW (W < 0.05) had been observed in the fish fed with the rations contend 0.8; 1.0 and 1.2% of Pt. The best FL was with ration 0.8% and the worst FC was observed for the ration with 0.4% of Pt, the lowest SU was proportionate for the ration with 1.2% of Pt. Through LRP (Linear Response Plateau) analysis was observed a linear increase in the FW with plateau in 0.74% of Pt. The requirement of Pt for Nile tilapia fingerlings is 0.74%
