A 56 days feeding trial was conducted to study the impact of starvation followed by re-feeding on growth performance of Indian pompano juveniles. 450 juveniles (mean ± SE, 16.69 ± 0.22 g) were divided into 3 treatments in triplicates. Control group (C) was fed to satiation three times a day and other two experimental groups were designated as 2S (2 days starvation) and 1S (1day starvation) i.e. re-feeding for 5 and 6 days in 2S and 1S respectively. At the completion of 28 days of culture (4 feeding cycle), it is resulted that 1S and C fed group performed with similar (p > 0.05) growth performance in terms of weight gain and specific growth rate indicating that complete compensatory growth occurred. Whereas, pompano juveniles maintained in 2S and 1S showed significant (p  0.05), and lowest was observed in 2S at the end of the experiment. There was no significant difference in condition factor among all the treatments. Moisture, total lipid, ash, glycogen content of liver and muscle were significantly varied among the treatment groups (p
