In order to investigate the modulating effect of hydrogen-enriched water on the transport stress of juvenile largemouth bass,Micropterus salmoides.In the present study,California perch fingerlings were simulated to be transported for 4 h,and then hydrogen-enriched water was passed through the control group(no hydrogen),and three hydrogen concentration groups(0.3 mg/L,0.5 mg/L,1.0 mg/L)were set up,which were sampled in the hydrogen-enriched water at 0 h,2 h,6 h,12 h,and 24 h,respectively.The results showed that the liver damage indicators of California perch fingerlings were elevated after transport stress,and the activities of AST and ALT were significantly reduced(P<0.05)at 6 h of 0.3 mg/L hydrogen exposure compared with the control group.Nach 6 Stunden war die Aktivität der Superoxiddismutase(SOD)bei allen Wolframkonzentrationen signifikant höher(P＜0.05)als bei der Kontrolle.Glutathione peroxidase(GSH-PX)activity was elevated at hydrogen concentrations of 0.3 mg/L and 0.5 mg/L.Tissue section observations showed that 0.3 mg/L,0.5 mg/L hydrogen passages for 6 h improved hepatocyte hollowing and intestinal inflammatory infiltration.The experimental results showed that hydrogen passage for 6h at 0.3 mg/L and 0.5 mg/L concentrations could alleviate the transport stress in California perch fingerlings.
