Karboksin’ in Gökkuşağı Alabalıkları (Oncorhynus Mykiss)’nda Süperoksitdismutaz Enzim Aktivitesi Üzerine Etkisi

Abstract

Carboxin, one of the most widely used fungicide in agriculture, but information about toxicity on fish is limited.In this study it was aimed to determine the effects of exposure to carboxin on the antioxidant defense system of rainbow trout (Oncorhynchusmykiss). Fish were exposed to carboxin (3,85 ppm) for 7 days. Antioxidant parameter (superoksidedismutaze, (SOD)) was measured in fish liver samples. The results indicated that carboxin exposure significantly affected the activity of SOD in rainbow trout liver (p< 0.01). So, it was assumed that carboxin caused oxidative stress in the rainbow trout and SOD enzyme took part in protection against carboxin toxicity
