  The aim of present study was to compare oxidant and antioxidant status of Çoruh trout (Salmo coruhensis), Anatolian trout (Salmo rizeensis) and rainbow trout (Oncorynchus mykiss) spermatozoa. Fish were obtained from Uzungöl. Enzymatic antioxidant activities (superoxide dismutase, catalase, glutathione peroxidase), glutathione and lipid peroxidation (malondialdehyde) were determined in spermatozoa of three trout species. Results indicated that catalase (23.36±0.36 K/g.protein), glutathione peroxidase (74.00±1.5 U/g.protein), glutathione (0.57±1.24 µmol/g.cell) and malondialdehyde levels (6.55±2.01 nmol/g cell) were highest levels in Anatolian trout (S. rizeensis) spermatozoa. In conclusion, differences among species caused alterations in the antioxidant and malondialdehyde levels.

  In the present study was determined the effects of monthly variability on enzymatic antioxidant (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px)), antioxidant (reduced glutathione (GSH)) and the oxidant status (nitric oxide (NO), lipid peroxidation (MDA)) in hepatopancreas, muscle, gills and gonad tissues of freshwater crayfish (A. leptodactylus) the monthly collected throughout the year from Keban Dam Lake of Turkey. Results indicate that variations in oxidants and antioxidants with relation to month were not only tissue specific but also were gender specific. The levels of oxidant parameters were generally higher in hepatopancreas in comparison to muscle, gills and gonad of crayfish. Moreover, in tissues were also determined the different oxidants and antioxidants responses in moulting, mating, breeding and egg laying periods.
