Van Balığında (Alburnus tarichi Güldenstädt, 1814) Üreme Göçü Sırasında Oksidatif Stresin Araştırılması

Van Balığı, Türkiye’nin en büyük gölüne endemik anadrom bir türdür. Balıklar, her sene üremesinigerçekleştirmek için alkali Van Gölü’nden göle dökülen tatlı sulara göç ederler. Balık bu göç sırasında açlık, tuzve pH adaptasyonu gibi farklı stres faktörlerine maruz kalır. Bu çalışmada, Van Balığının üreme göçü öncesi vesonrasında plazma, solungaç, karaciğer, beyin ve kas gibi dokularındaki total oksidan ve antioksidan, lipidperoksidasyon ve DNA hasarları karşılaştırıldı. Total oksidan durum (TOS) üreme öncesi gölden yakalananbalıkların karaciğer ve böbrek dokularında, total antioksidan durum (TAS) ise akarsudan yakalanan balıklardakaraciğerde, gölden yakalanan balıkların ise beyin ve böbrek dokularında yüksek olduğu bulundu (P

Investigation of Oxidative Stress in Van Fish (Alburnus tarichi Güldenstädt, 1814) During Reproductive Migration

Van Fish is an anadromous species of endemic to Turkey’s largest lake. The fish migrate to the freshwater pouring from the alkaline Lake Van to the lake for the reproduction every year. Fish are exposed to different stress factors such as fasting, salt and pH adaptation during migration. In this study, total oxidant and antioxidant, lipid peroxidation and DNA damages in tissues such as gill, liver, plasma, brain and muscle were compared before and after reproductive migration. Total oxidant status (TOS) of the fish caught in the lake before reproduction, liver and kidney tissues, total antioxidant status (TAS), fish liver caught from freshwater, fish from the lake were observed to be high in the brain and kidney tissues (P
