Outlooks of using small lakes of Novosibirsk region

The paper explores 11 lakelets in order to design the recommendations on stocking them with certain types of fish. Zooplanktone is represented by 32 species from three systematic groups. Zooplankton species diversity varies from 5 to 16. The dominant complex of species is very different.. In some lakes, the leading role belongs to the cladocerans. In other lakes, different species of copepods play a dominant role. The rotifiers dominate in two lakes. The quantitative indicators of zooplankton in the lakes differ significantly from each other. The highest number of zooplanktone is 1312,7, the minimum-26,7 thousands units / m3. The maximum zooplankton biomass was observed in the most saline lake where its value reached 70,7 g/m3. The least biomass was 0.1 g / m3. The zoobenthos contained 29 species from 11 large taxonomic groups. The most numerous group (19 species, 65.5% of the total number of taxonomic composition of benthic animals) consisted of chironomids, oligochaetes (3) and biting midges (2). Other groups consisted of one specie. The number of species in the lakes varied from 2 to 15. The highest parameters of the number was 973 samples/m2, biomass - 7.33 g/m2; the lowest parameters for the number and biomass were 26 samples/m2 and 0.16 g/m2 . According to zooplankton biomass and capacities for breeding fish lake planktophagous, 2 lakes out of 11 refer to those which have insufficient nutrients; other lakes refer to average lakes with sufficient nutrients to extremely nutrient lakes. Taking into account regional standards, equal to 50 kg/ha when breeding Peled, the authors recommend the Ploskoe lake, the Bogatikha, the Gorbunechnoe and the Sladkoe for commercial fish breeding. Considering development of zoobenthos, 7 lakes out of 11 belong to those which have insufficient nutrients. The Ploskoe lake, the Kamennoe, the Kalach and the Sladkoe are average lakes with sufficient nutrients and extremely nutrient ones. The authors recommend them for breeding carp and common carp.
