摘要
This work describes the dynamics of the vendace population in Syamozero and provides an evaluation of its current state based on data collected for more than 75 years. The main biological parameters of the fish (body length and mass, gender, maturity stage, and fecundity) are analyzed. The causes of variations in the vendace number from year to year are considered.
