Abstract

In October 2018, after the change in the temperature profile and chlorophyll concentration, we recorded the changes in the distribution parameters of mesozooplankton in the surface 100 m layer at the station located in the pelagic zone of Lake Baikal. The study was carried out on horizons of 0-50
and 50-100 m. Measurements were performed using an AAQ-Rinko water quality probe (JFE, Japan), a SBE-25 CTD probe (SeaBirdElectronics, USA) and a Furuno FCV-1100 sonar (Furuno, Japan). We found a deepening of zooplankton after the immersion of the chlorophyll and temperature maximum.
