Abstract: The effect of starvation for different days (0,2,4,6 and 8 days) and compensatory growth on energy budget of juvenile cobia (Rachycentron canadum) was estimated by an experimental ecological method.Results in present study indicated that energy content and body weight of juvenile cobia decreased significantly after starvation,and during the re-feeding period,ingestion rate in energy and specific growth rate in energy,wet weight and dry weight in the deprived fish were higher than those of control fish.Results also indicated that juvenile cobia showed complete compensatory effect in the recovery growth and it was contributed by the increase of ingestion rate.Energy budget of juvenile cobia fed to satiation was 100.00C=38.33G+15.06F+7.22U + 39.39R,and expression by assimilated energy was 100.00A=49.32G+50.68R.

Key words: Juvenile cobia, starvation, compensatory growth, energy budget
