The fish stock of the Orlik reservoir, Czech Republic was surveyed by shore seining and scientific echosounder (Simrad EY 500). Reservoir was dominated by cyprinids (roach, bream) with considerable share of predatory fish and perch. Inshore biomass an abundance was 302 kg/ha and 3920 inds/ha respectively. Populations show sustainable recruitment without variation of year class strength. The open water biomass estimated by hydroacoustics was 145.5 kg/ha. Assuming hydrological conditions of light flood in June 2004 it was not possible to trace any changes of the fish stock of the reservoir connected with the operation of the Temelin nuclear power station.
