In this study, the effect of short-terms starvation (0, 1 and 2 weeks) on biochemical parameters and non-specific immune response of tinfoil barb (Barbonymus schwanenfeldii) was investigated. Fish in three different groups were deprived of feed for 0 (control), 1 (S1) and 2 (S2) weeks, respectively. At the end of the experiment, blood samples for biochemical and immunological analyses were collected. Plasma peroxidase level and haemolytic complement activity were significantly lower in starved fish for 2 weeks than in fed fish and in starved fish for 1 week. Plasma lysozyme activity was significantly affected by starvation periods in all treatment groups. However, no significant effect was observed on plasma antiprotease activity. The results indicated that plasma glucose and cholesterol levels were significantly lower in the S2 group than in the control and S1 group. There were significant differences between the control and the food deprived groups in plasma triglyceride levels. Starvation caused an increase in plasma total protein, albumin and globulin in the deprived groups compared to the control group. The results of this study showed significant changes in non-specific immune parameters, plasma glucose levels and other metabolites in this species after feed deprivation that are indicative of the relationship between starvation effects and the extension of starvation period.
