                Abstract

 Some morphometric characteristics, condition factor, age groups of vendace (Coregonus albula L.) of Paravani Lake (South Georgia) have been given for the first time since 1970.  Growth rates in accordance with the age were compared using Fulton's condition factor. The study of annual growth was based on back-calculations of length. It was shown that nowadays in Paravani Lake quantity of vendace, as well as length and weight rate were diminished. The reasons of such changes are discussed.

   Key words: Vendace (Coregonus albula), Paravani, Georgia.
