摘要: Transport procedures usually cause fish stress. The purpose of this study was to investigate the effect transport stress on blood biochemical profiles, oxidative biomarkers, and hepatic heat shock proteins (HSPs) channel catfish (Ictalurus punctatus). Fish (body weight 55.57± 5.13 g) were randomly distributed two groups, control treatment. group kept under normal culture conditions. treatment exposed process (3.5 hrs.). samples collected before transport, after packing at 0, 1, 6, 24, 72, 168 h respectively. caused a significant increase in serum concentrations cortisol, glucose, total cholesterol, triglyceride, as well activity aspartate aminotransferase 0 1 compared with non-transported basal level. Blood protein content significantly declined transported fish. Total antioxidant capacity, malonaldehyde content, activities both glutathione peroxidase catalase increased within 6 hours transport. exhibited higher level either concentration nitric oxide or mRNA expressions HSP70 HSP90. It is concluded that triggers response I. punctatus, leading obvious change capacity. punctatus need be more care recover from
