Such a great fish - "Issyk-Kul dace (chebachok)" (Leuciscus bergi close-up). Until the early 1970s, L. bergi was the dominant fish in the lake. It was found down to depths >100 m, and reached a maximum body-length of 16.5 cm and weight of 60 g. During recent years, however, the number and distribution of this species have sharply declined. Of the three types, i.e. the inshore, the semi-migratory and the fast-growing, the first two declined the most. Leuciscus schmidti has a biology similar to that of L. bergi, but the former species seeks food in deeper water and prefers feeding on plankton.
