Abstract

The present study was carried out at the Mariculture research center (M.R.C.) of the Suez Canal University, EL-Arish, North Sinai, Egypt. It aims to evaluate the feasibility of Red Tilapia culture in salt water. Effect of feeding levels and feeding regimes on growth performance and feed utilization of Red Tilapia fingerlings. Three feeding levels (2, 3 and 4% of total fish biomass) and within each feeding level two feeding frequency (4 times/day and 6 times/day). The fish had an average initial weight of 5.50 g and 32% crude protein were tested .The results showed that: The fish fed on 4% feeding levels from total fish biomass and 4 times /day have the heaviest final body weight (29.68+4.35 g) and have a daily weight gain and specific growth rate of 0.28+0.05 (g/fish/day) and 1.98+0.16 (%/day) , respectively.
