History of the zoocenosis of Lake Glubokoe according to animal remains in the bottom sediments,. A 50 cm core from the lake bay has also been studied. Cladocera dominate at 50–40 cm and near the surface. Porifera spicules are abundant at 20–10 cm while Protozoa are numerous at 30 cm. Among the Cladocera, planktonic forms are less important than in the main lake basin.

Feeding of fish in Lake Glubokoe,ed a considerable decrease in the share of perch (from 31% to 2%) and ruff (from 18.5 to less than 0.1%) in 1984..The richest food resource in the lake is crustacean plankton. In summer, it is mostly consumed by roach. Estimation of the electivity shows that, unlike perch, roach selectively consumes
