Zusammenfassung:FIELD: processing of fish skins; may be used in leather industry. SUBSTANCE: soaking-defatting of fish skins is carried out in aqueous solution of alkali lipase lipoaerusine (0.02-0.5% from skins mass) and neutral protease (0.01-0.4% from skins mass) at temperature 20-25 C and pH 6-10.5. Method allows to produce leather half-finished product with specific drawing of right side and high degree of defatting. EFFECT: higher efficiency. 2 tbl, 3 ex
