SummaryThe effects of angling on oxidative/antioxidant systems in tench (Tinca tinca) were tested to determine oxidative stress. A total of 50 tench (1-year-old, 16 cm TL) were captured in a 1800 m 2 pond and transferred to an aerated tank for sampling (n = 5) 3 h later. Forty-five of the tench were stocked in a 50 m 2 pond and recaptured (n = 5 per sample) 2, 7, and 17 days thereafter. The remaining five tench were used as the control. Superoxide anion, superoxide dismutase (SOD), and lipid peroxides were determined in the liver, brain, white muscle, and gills. Results indicated that there were changes in the liver superoxide levels 2 days after angling, but there were no enzyme responses or increases in lipid peroxidation. Superoxide anion values returned to normal 7 days after capture. The conclusion is that tench can recover within a short period of time from the oxidative stress caused by angling.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
