This study was conducted in order to measure glucose, cholesterol and hematocrit as indicators to evaluate the effect of caraway seeds meal (CSM) on the health and resistance of common carp to salinity stress. To attain this goal, fish (2.457±0.057 g) were divided into four groups fed on diets containing different levels of CSM; 0 (control), 0.5, 1 and 1.5%. After 56 days of feeding, blood samples of the fish were obtained in five stages (once before and four times after stress) to evaluate glucose, cholesterol and hematocrit levels. The experiments indicated that salinity sign-ificantly affected glucose, cholesterol and hematocrit. On the first day after stress, the hematocrit and glucose levels were considerably increased in all groups compared with their levels before stress. After stress, cholesterol level signif-icantly decreased in all groups compared to before stress. The level of hematocrit indicated no significant difference among the groups before and after stress. On the first day after stress, the glucose levels significantly increased in trea-ted groups with CSM compared with the control group. The glucose and hematocrit levels were decreased gradually in all groups from the third day on. After stress, no differences were observed for survival rates among the experimental diets. However, the highest survival rate belonged to treated groups with CSM. The overall result indicated that the suplement of CSM has a positive influence on the glucose, hematocrit and resistance of common carp to salinity stress.
