The Aquatic Fauna of Water Bodies in the Maly Patok River Basin (the Subpolar Urals). 1. Fishes

aInstitute of Biology of Komi Scientific Centre of the Ural Branch of the Russian Academy of Sciences, Syktyvkar, 28, Kommunisticheskaya str., Syktyvkar, Russia, 167982


The materials of long-term studies (1996–2017) on the fish fauna in the basin of the Maly Patok River, which is the key river in the watershed of European and Siberian rivers and the boundary between the Subpolar and Northern Urals areas, have been generalized. The local ichthyofauna consists of 11 species, including anadromous (Atlantic salmon or summer salmon), semidiadromous (Siberian whitefish) and nonmigratory species. Сиг образует здесь полупроходную озерно-речную форму. The Siberian whitefish, an invader, forms a semidiadromous lake and river form here. A trend towards an increasing role of Siberian whitefish in formation of the fish part of the aquatic community in a wide range of the lakes located in the mountainous belt area has been identified along with a decreasing share of the previously dominating perch.

Keywords: Subpolar Urals, western slopes, mountain rivers and lakes, the Maly Patok River basin, ichthyofauna.

Taxonomic Structure and Ecology of Phytoplankton of Small Forest Lakes in the Zone of Technogenesis of Sulfide Deposit (South Urals)

aIlmen State Reserve, Chelyabinsk Region, Miass, 456317, Russia


Taxonomic diversity of phytoplankton in the small forest lakes of the South Ural on the area of sulphide copper-zinc pyrite deposits and in the zone of influence of the impact of cooper smelting factory is reduced in a gradient of increasing fluctuations in acidic, the concentrations of heavy metals Cu, Zn, Pb, Cd, Fe, Mn and exceeded the content of sulfate on the hydrogen-carbonate. In acidic conditions pH 5.1–7.2 of forest lakes of buffer zone of influence of technogenesis increase of species diversity Chrysophyta and abundance of some species of Golden algae, green algae of orders Sphaerophorales, Chlorellales was revealed. Periodic acidification, the relatively low excess concentrations of metals and mixotrophic conditions provide competitive advantages for the development of some species Chrysophyta in some lakes of impact and buffer zone of influence of technogenesis.

Keywords: phytoplankton, taxonomic structure, species diversity, dominant species, impact, technogenesis, acidification, small forest lakes, South Urals.

bPapanin Institute for Biology of Inland Waters, Russian Academy of Sciences, Borok,
Nekouzskii raion, Yaroslavl oblast, 152742 Russia


The ecology and seasonal development of Ranunculus nipponicus in nonfreezing watercourses on the northern coast of the Sea of Okhotsk (59° N) were studied. For the first time on the territory of Russia the year-round vegetation and flowering without the formation of a resting stage of the water crowfoot were marked. During all months of the year, growth of shoots, the formation of young roots, buds and cleistogamous flowers are observed at an average monthly water temperature of +0.1 °C to +5.8 °C. The most intensive formation of young roots in February–March and the most appearance of underwater flowers in late March – early April is not associated with increase of water temperature. Cleistogamous flowering rarely leads to the formation and maturation of the fruit, perhaps because of too low a water temperature.

Keywords: aquatic vascular plants, Ranunculus nipponicus, ecology, seasonal development habitat conditions, Magadan Region, Russia.

Interannual Changes in the Invertebrates in the Littoral and Pelagic Zones of Lake Sevan (Armenia) with Fluctuations in Meteorological Conditionsand Fish Biomass. II. Autumn Zooplankton

1 Papanin Institute for Biology of Inland Waters, Russian Academy of Sciences, Borok, Russia
2 Institute of Hydroecology and Ichthyology, Scientific Centre of Zoology and Hydroecology, National Academy of Sciences of the Republic of Armenia, Yerevan, Armenia


Annual changes in the quantitative characteristics and structure of zooplankton in the pelagic and littoral zones of Lake Sevan in October were determined by a number of factors among which the biomass of the main planktophage, whitefish (Coregonus lavaretus Linnaeus, 1758) had the greatest effect. The richest communities were formed due Cladocera at decreased biomass of whitefish, minimum increase in the water level, and high average monthly temperatures for the period of April-October. In the littoral zone, the zooplankton is affected by a number of unaccounted factors, and the influence of planktophagous fish, mainly inhabiting found in deep-water areas, is less pronounced. A significant increase in biomass of planktophagous fish in 2016–2017 led to the reduction of quantitative characteristics of zooplankton, resulting in decreased water clarity.

Keywords: : Lake Sevan, zooplankton, autumn, interannual variability, abundance, biomass, cladocerans, precipitation, air temperature, water level, ichthyomass.

Invertebrate Drift in Two Streams of the Kunashir Island (Kuril Archipelago)

aFederal Scientific Center of the East Asia Terrestrial Biodiversity,
Far Eastern Branch, Russian Academy of Sciences,
690022 Vladivostok, 100-letiya Vladivostoka Avenue, 159, Russia


The parameters of the drift and quantitative indicators of zoobenthos in streams of the island, which is a part of the Kuril Archipelago, have been estimated for the first time. Hydrobionts drifting during the daylight are smaller than those drifting in the dark, that can be the consequence of food selectivity of the visually oriented drift-feeding fishes. Since the upstream movement of zoobenthos contributes to obtaining of overestimated coefficients of the specific drift rate, it is proposed to use a value of drift rate during one exposure of driftnet for their calculation.

Keywords: Kuril Islands, stream ecosystem, drift-feeding fishes, upstream movement of zoobenthos.

cSurgut State University, Lenina av., 1, Surgut, 628403 Russia


The qualitative and quantitative characteristics of zoobenthos and zooperiphyton of two model oxbow lakes from the Middle Ob basin are presented. Three sites in the each oxbow lake are examined: in the apex or “pond” site, least connected with the river, in the middle part and near the channel, flowing into the river. The specific longitudinal structure of the taxonomic composition and the abundance of zoobenthos and zooperiphyton are revealed. The most favorable conditions for zoobenthos are in the “pond” site, for zooperiphyton ‒ in the middle of oxbow lake and near the channel. In order to identify and understand the general patterns of aquatic ecosystems functioning, the obtained results are discussed in the light of the well-known theoretical concepts – the ecotone, the edge effect, and the lake continuum.

Keywords: zoobenthos, zooperiphyton, oxbow lakes, density, biomass, taxonomic composition, distribution inhomogeneity, Western Siberia.

Amino Acids Composition of Green Microalgae and Diatoms, Cyanobacteria and Zooplankton (Review)

aInstitute of Biophysics, Siberian Branch, Russian Academy of Sciences, Akademgorodok, 50/50, Krasnoyarsk, 660036, Russia
bSiberian Federal University, Svobodny Av., 79, Krasnoyarsk, 660041, Russia


We reviewed foreign and domestic literature devoted to the study of amino acid composition of aquatic organisms, representing major groups of producers (green microalgae and diatoms, cyanobacteria) and primary consumers (zooplankton). Based on published data we estimated the composition of essential and nonessential amino acids of microalgae, cyanobacteria, zooplankton, and determined their differences. It is concluded that the amino acid composition of major groups of plankton is heterogenous. The role of amino acids as a limiting factor for the development of herbivorous zooplankton is discussed. We demonstrated the prospects and the need for further study of amino acid composition in order to develop a complete theory of functioning of aquatic ecosystems.

Keywords: amino acids, microalgae, Cyanobacteria, zooplankton, aquatic ecosystem.

Effects of Roundup Herbicide at Low Concentration and of Thermal Stress on Physiological and Biochemical Parameters in Amur Sleeper Perccottus glenii Dybowski Juveniles

1Papanin Institute for Biology of Inland Waters, Russian Academy of Sciences,
Borok, Nekouzskii raion, Yaroslavl oblast, 152742 Russia
2Yaroslavl State University of Medicine, ul. Revolyutsionnaya, 5, Yaroslavl, 150000 Russia


The effects of 30-day exposure to Roundup at concentration of 2 μg/L and of thermal stress on the intestinal glycosidase activities (maltase and amylolytic activities (AA)), brain acetylcholinesterase (AChE) activity and water-soluble protein (WSP) content in juvenile specimens of Amur sleeper Perccottus glenii Dybowski have been studied. Additionally, critical thermal maximum (CTM) and final selected temperature (FST) are determined in fish of control (exposure to 0 μg/L Roundup) and Roundup-exposed groups. After Roundup exposure AA and WSP content were 27% and 31% lower respectively, maltase and AChE activities did not change. An increase in water temperature at a rate of 8 °C/h decreased AA by 60%, maltase activity by 18% and WSP content by 28% in fish of the control group; but decreased AA by 76%, AChE activity by 29%, WSP content by 40%, and increased maltase activity by 11% in fish of the Roundup-exposed group. The recovery treatment during 12 days in a thermal gradient with herbicide-free water (temperature range between 14 and 31 °C) reduced the inhibitory effect of heating on AA, but increased it the on AChE and WSP content in fish from both control and Roundup-exposed groups (on maltase activity only in the fish of exposed group). No significant differences were noticed in CTM and FST values in fish of control and Roundup-exposed groups.

Keywords: Amur sleeper, maltase, amylolytic activity, AChE, water-soluble protein, upper sublethal temperature, final selected temperature, Roundup, thermal stress.

аPapanin Institute for Biology of Inland Waters, Russian Academy of Sciences, Borok, Nekouzskii raion, Yaroslavl oblast, 152742 Russia
bRussian-Vietnamese Joint Tropical Research and Technology Center, Nha Trang,
Khanh Hoa, Vietnam


At present, invasive fish species dominate in terms of abundance and compete for environmental resources and ecological niches with native species in some freshwater waterbodies and watercourses of Central Vietnam, which can ultimately lead to decrease in the diversity and to the transformation of fish communities. Data on the distribution and biology of the mass alien species, posing the most serious threat to tropical freshwater ecosystems, including Vietnam: pterygoiplicht Pterygoplichthys spp. (Loricariidae) and Nile tilapia Oreochromis niloticus (L.) (Cichlidae) are considered. These invasive species are shown to possess high adaptive potential. It is noted that invasions, as well as deliberate and accidental introduction of alien fish species, can have negative consequences for the biodiversity of Vietnam's aquatic ecosystems.

Keywords: alien species, Nile tilapia Oreochromis niloticus (L.) (Cichlidae), armoured catfishes (Loricariidae), Pterygoplichthys spp., biodiversity, aquatic ecosystems, Vietnam.
