Аннотация: At the beginning of August, 2 months after 20 000 t of diesel fuel spilled into the Bezymyanny Stream (which took it out to the Daldykan and Ambarnaya rivers), the large Norilsk expedition of the Siberian Branch, Russian Academy of Sciences, sampled net zooplankton at 13 stations located in both sections of these rivers and Lake Pyasino with the Pyasina River outflowing from it. A comparative analysis of the species composition, abundance, biomass, and saprobity index of zooplankton at these stations has been carried out. The productions of rotifer and crustacean zooplankton and potential production of planktivorous fish in Lake Pyasino have been calculated. Based on the state of zooplankton, a gradual improvement in water quality has been observed from river areas exposed to the oil products to the northern part of the lake and the River Pyasina outflow. The low abundance and biomass of zooplankton in the lake (43 800 +/- 17 550 ind./m(3), 112.8 +/- 26.2 mg/m(3), on average) due to the dominance of rotifers (Ploesoma truncatum (Levander), Bipalpus hudsoni (Imhof), and Conochilus unicornis Rousselet) resulted in low values of zooplankton production and the potential production of planktivorous fish (0.85 kg/ha per season).
