Nowadays, herbal products as a new class of growth promoters that provide an alternative feeding strategy to replace antibiotic growth promoters in aquaculture. This study was conducted to investigate the effects of different levels of sangrovit (0, 0.05, 0.1 and 0.15 %) on growth, some of blood biochemical parameters, survival and salinity tolerance capacity in Cyprinus carpio (2.62±0.117 gr). After 45 days of feeding, results showed that growth performance including of weight gain and % specific growth rate improved which fish fed whit sangrovit compared with to control group, but there was no significant differences in growth parameters which fish fed with herbal supplement compared to control group (P>0.05). There were significant differences in biochemical parameters in fish fed with sangrovit compared to the control group (P<0.05). The lowest level of cholesterol was observed in 0.05 % group and the highest level of total protein was observed in 0.15 % group. The highest levels of glucose observed in control treatment. In order to determine the effect of the herbal supplement on resistance to salinity stress, salinity stress was carried out after 45 days of feeding. Blood samples were obtained at 24, 72, 120 and 168 hours after stress. Hematocrit had significant difference in each groups (P<0.05). On the third day after stress, hematocrit levels were decreased in all treatments. Survival and tolerance to salinity stress challenge remained unaffected by dietary supplementation of sangrovit. The results of this study showed that addition of sangrovit to fish diet can improve growth performance and blood biochemical parameters of common carp fingerlingsJournal
