Modern features of the morphology and growth of scales in sparsely rakered whitefish Coregonus lavaretus lavaretus (Coregonidae) in lake Imandra under intensive industrial pollution // Transactions of Karelian Research Centre of Russian Academy of Science.

Keywords: whitefish Coregonus lavaretus, Lake Imandra, scale morphology, back calculations.
The morphology and size-age features of scales in sparsely rakered whitefish Coregonus lavaretus lavaretus from three localities in Lake Imandra differing in human pressure have been studied. The growth rate of anterior, lateral and posterior parts of scales during the life of the fish was uneven, whereas the scale shape was constant. It is recommended to use the anterior diagonal radius of a scale using R. Lee formula for back calculations of fish body length.
