Single or combined effects of medicinal plants, garlic (Allium sativum) and ginger (Zingiber officinale) powders on hepatosomatic index, body composition, digestive enzymes and resistance rate in Sobaity sea bream (Sparidentex hasta) fry were investigated for 8 weeks. Biomar diet (54% protein and 18% lipid) supplemented with 0 (control), 1% garlic, 1% ginger and 1% garlic + 1% ginger in a totally randomized design trial in triplicate. A total of 240 fingerlings of 3.80 ± 0.31 (g) average weight were randomly distributed in 12 tanks. Results showed that there were significant differences in hepatosomatic index among treatments (p>0.05). Significant difference was observed in body composition (p>0.05), as protein and lipid contents in the whole body increased in fish fed with garlic/ginger and ginger groups. Lipase enzyme activity increased significantly in garlic/ginger and ginger groups compared to control group. The highest amylase enzymes activity was observed in ginger group (p<0.05). There was significant difference in survival index to acidity (pH=2), alkalinity (pH=12) and thermal (40°C) stress. In the test of pH and thermal stress, maximum of survival time was obtained in garlic/ginger and ginger groups, respectively (p<0.05).  In general, the fish fed with garlic/ginger powder had the highest body composition, digestive enzymes and resistance to environmental stress.
