Assessment of the bioresource potential of Kazan city’s lake ecosystems by phytoplankton indicators

Abstract

Nowadays protection and sustainable management of biological resources is of particular importance. The most important area of hydrobiological research is the assessment of the bioresource potential of aquatic ecosystems (Alimov et al., 2005). Phytoplankton is the basis of life and the most important component of the bioresource base in the aquatic ecosystem. Phytoplankton indicators (primarily abundance and biomass) are widely used to assess the bioresource potential of lakes due to its position as an autotrophic producer at the base of the ecological pyramid of the lake ecosystem (Bulion, 2005, 2019; Alimov, 1989, 2000; Alimov et al., 2005). Our study is aimed to research phytoplankton indicators to assess the bioresource potential of Kazan city’s lake ecosystems (Volga region, Russia).
