Abstract. Leather made from fish skins is used to create exclusive designer products, combining a unique aesthetic with durability and lightness, suitable for a variety of garments. However, susceptibility to biodegradation is a serious problem, especially for materials such as fish skin leather. The study examines the possibility of increasing the resistance to biodegradation, in particular to fungi, of leathers obtained from fish skins, by using nonequilibrium low-temperature capacitive discharge plasma during their production. Experiments on salmon and pike perch skins, including control samples and samples treated with plasma in various environments, showed that although air plasma treatment provides limited protection, argon plasma treatment prevents infection. The observed differences in resistance to fungal infection are explained by different processes substantiated by each type of gaseous environment. Argon plasma creates a potentially less nutrient-rich surface, while air plasma, due to its oxygen content and oxidative processes, inhibits colonization but does not prevent it. The results of the study indicate the effectiveness of the proposed method for producing leather from fish skins with increased fungal resistance, which allows us to recommend this method for use in the leather industry to obtain innovative material for the production of products with high aesthetic and performance characteristics.
