Abstract: The present study was conducted to determine the consequences of supplementing dietary salt on growth and feed utilization of tilapia (
Oreochromis niloticus Linnaeus, 1758) in laboratory condition for a period of 21 days. Four treatments with three replicates in each containing 30 fish (average weight, 2.2 ± 0.01 g) were stocked in 100 liter aquaria. Four treatments were designated as T
1 (SD+0% salt of diet), T
2 (SD+1.0% salt of diet), T
3 (SD+1.5% salt of diet) and T
4 (SD+2% salt). The fish were fed at 20% body weight twice a day. Significantly (p<0.05) higher weight gain of tilapia was found in T
3 (8.90 ± 0.31g) followed by T
2 (8.75 ± 0.29 g), T
4 (7.68 ± 0.07 g) and T
1 (5.23 ± 0.22 g). The highest length gained by the groups treated with T
3 (2.93 ± 0.19 cm) followed by T
2 (2.92 ± 0.04 cm), T
4 (2.73 ± 0.06 cm) and T
1 (1.84 ± 0.03 cm). Specific growth rate (SGR) (p<0.05) was found to be the highest in T
3 (8.16 ± 0.21) followed by T
2 (8.08 ± 0.23), T
4 (7.56 ± 0.06) and T
1 (6.20 ± 0.24). The highest survival was found in T
3 (85.55 ± 1.93) followed by T
2 (84.44 ± 1.93), T
1 (83.33 ± 0.00%) and T
4 (81.11 ± 1.92). The lowest food conversion ratio (FCR) was obtained in T
2 (1.15) than that of T
1 (1.57), T
4 (1.40) and T
3 (1.18), respectively. The growth parameters indicated that supplemental feed with 1.5% dietary salt can be incorporated in
O. niloticus diet.
