| Abstract | An on-farm trial was conducted in seven (7) farms in Nueva Ecija, Philippines, to investigate the effect of two onsets of feeding on the growth, yield, and survival of Nile tilapia. There were no significant differences on the performance data (final mean weight, daily weight gain, extrapolated gross fish yield, and survival rate) that were recorded in this study. The only statistically significant difference observed was in the total quantities of feed used in the trial. The 45-day onset in feeding produced a slightly higher mean gross value of the crop (P205,617 ha-1) compared with the 75-day delay (P197,063 ha-1) but by delaying the start of feeding to 75 days, the costs were reduced such that the net value of the crop was improved (P124,242 ha-1 in 75-day delay vs. P106,026 ha-1 in 45-day delay). |
