The reported study has been undertaken to check if the shape of vendace scales can be a parameter permitting reliable differentiation between the populations of fish from three lakes. The measurements were made on 354 scales of 144 vendace individuals (Coregonus albula) from lakes Drawsko, Pe?cz and Morzyckoin West Pomerania area, NW Poland. The scales were subjected to 12 morphometric procedures defined in the program called Digishape for automatic morphometry. Step discriminant analysis confirmed statistically significant (P<0.001) differences in the shape of scales between three fish populations, with the mean accuracy of classification matrix at a level of 73.45%. According to the results; it is possible to distinguish the fish from the three populations studied, from three lakes in West Pomerania, on the basis of the shape of scales. This finding can be an interest for fish farming and protection of biodiversity
