Peculiarities of Roach Population Structure in Lake Baikal
The variability dynamics of roach populations in Lake Baikal was studied in terms of ichthyomass culmination correlation with mass fertility age according to the results of long-term observation. Data on age structure of roach based on fishing catches in the Selenga and Barguzin regions of Lake Baikal in terms of its relative number and ichthyomass are presented.
