Ismailov Kh., Yuldashov M.A., Kamilov B.G.

Abstract: Hydrochemical, hydrobiological and fish species composition in Talimardjan reservoir (Uzbekistan) was studied under conditions of newly created culture based fisheries. Water quality characteristics are suitable for freshwater aquaculture. Macrophytes developed poorly. Totally 131 species of phytoplankton were determined in samples including Cyanophyta (42), Bacillariophyta (54), Chlorophyta (22), Dinophyta (7), Cryptohyta (3), Euglenophyta (3). Quantity of algae was 150.20*103 -46620 *103 cells/l; biomass 55.8 - 355, 9 mg/l. Zooplankton was represented by 40 species; quantity varied 290.1 410.1 thousands specimen /m3, biomass 0.6 1.1 g/m3. Zoobenthos was represented with 5 species of chironomids; quantity varied 406 601 speciemens/m3, biomass 3.9 5.1 g/m3. Totally 35 fish species were determined in reservoir including 11 native and 14 invasive species.
