Abstract: The present study was conducted to evaluate the effects of mash feed, sinking feed and floating feed on growth performance, feed utilization and hematology of Nile tilapia (Oreochromis. niloticus). The study was assigned in Completely Randomized Design (CRD) with three treatments and four replicates. Fish with average weight 13.30± 0.85 g. were fed three experimental diets mash feed, sinking feed and floating feeds that had the same proximate composition of 47.48 % crude protein, 11.18 % crude lipid, 12.90 % ash, 3.09 % fibre, 25.35 % NFE as starch and sugar, 2.60 % calcium, 1.50 % phosphorus. The fish were fed experimental diets at the rate 3.0-5.0 % of their body weight per day, twice daily for four weeks. At the end of the experiment, there were no significant differences (P>0.05) among the treatments in weight gain (WG), average daily gain (ADG), feed conversion ratio (FCR). Specific Growth rate (SGR) was significantly different(P>0.05) between the treatments. The highest SGR was found in fish fed floating feed, followed by fish fed sinking feed, whereas the lowest value was found in mash feed. Feed is the major source of nutrients inputs to the fish culture but only small amount of nutrients in feed was converted by Nile tilapia (23.36- 34.08% for TN and 28.50-42.35% for TP). Total Nitrogen (TN) and Total Phosphate (TP) retention in tilapia were significantly higher (P<0.05) on fish fed the floating feed than the sinking and mash feed. Total Nitrogen (TN) and Total Phosphate (TP) output in water were significantly higher (P<0.05) on fish fed the mash feed than the sinking and floating feed. Fish fed floating and sinking feed exhibited a significantly higher level (P>0.05) of serum protein. In this case, the level of serum protein was lower in mash feed. However, no significant differences (P>0.05) were observed for red blood cell (RBC) count, hemoglobin (Hb) concentration, hematocrit (Ht) percentage and immunoglobin (IgM) level. From the economic point of view, feed cost to produce one kilogram of tilapia actually higher in mash feed. Results from this study demonstrate that fish fed floating and sinking feed both had improved growth performance than mash feed and had financially feasible than mash feed.
