We determined the contents of total glutathione (tGSH), reduced glutathione (GSH), and oxidized glutathione (GSSG) and values of the glutathione redox index (GSH RI) in hepatopancreas, gills, and muscle of three freshwater crayfish species: noble crayfish (Astacus astacus) from the Southern Morava River, stone crayfish (Austropotamobius torrentium) from the Krajkovačka River, and spinycheek crayfish (Orconectes limosus) from the Danube River. The obtained data show strong tissue and species specifity of investigated parameters: tGSH, GSH, GSSG, and GSH RI in the hepatopancreas, gills, and muscle of the indicated crayfish species. Our work represents the first study of its kind and showed that the investigated parameters can be considered suitable biomarkers of the cellular glutathione redox status in of freshwater crayfish species.
