Abstract
The aim of the current experiment was to examine the economic efficiency, growth and feed costs of the Nile tilapia subjected to different levels of areal feed inputs during the production cycle. Four feeding strategies were employed; the control treatment included continuous feeding of 8 grams commercial diet/m 2 /day for 155 days. T1, T2 and T3 included feeding corn at 1.5, 3 and 5 % of biomass, respectively for 60 days, followed by feeding commercial diet at 4, 6 and 8 g/m 2 /day for additional 95 days, respectively. Consequently, it is recommended to feed Nile tilapia at 8 g diet/m 2 /day when rearing during the production cycle in order to obtain acceptable growth with higher economic returns
