چکیده
the present study investigated effects of starvation on growth, body chemical composition and non-specific immune parameters in yellow fin seabream. in this study, 120 fish with a mean length of 8.05± 0.98 cm and weight of 7.46± 1.07 g (was referred as size a) and 120 fish with a mean length of 11.05 ± 0.86 cm and weight of 18.01± 3.07 g (was referred size b) were used with each size was comprised of those fed and starved with three replicates (20 fish per replicate) in a 60- l plastic tanks. the specimens were sampled at 10, 20 and 30 days of food deprivation. the results showed that in starved group of size a, specific growth ratio (sgr), condition factor (cf), final weight, increased weight gain (iwg), hepatic- somatic index (hsi), decreased significantly (p
