The first record of the rotifer Ascomorpha ovalis (Bergendal, 1892) in Lake Glubokoe (Moscow Region) in June 2010 is described. Long-term observations of zooplankton dated back to 1897, including our own studies started in 2004 and carried out on a yearly basis, have never recorded this species before 2010.The density of the population was 25 ind./L in the water column of 0–10 m. The studies of 2011–2012 demonstrated that the species did not disappeared from plankton but naturalized in the lake. The species A. ovalis is indicative of oligotrophic conditions. Along with the oligotrophic rotifer Gastropus hyptopus (Ehrenberg, 1838) which was earlier detected in the lake, the penetration and naturalization of Ascomorpha ovalis in the pelagial in the recent years indicates continuous the tendency for increasing oligotrophication of the pelagial in Lake Glubokoe.

Keywords: rotifers, bioindication, Glubokoe Lake, oligotrophication.

Fauna of parasites of burbot from Baikal rift zone (lake Baikal, lake Khuvsgul, Tsipo-Tsipikan and Kuanda-Chara lakes) includes 46 species of 11 classes. The species composition of fauna of parasites of burbot decreases in the following sequence: Lake Baikal (37 species) > lakes Tsipo-Tsipikan (18 species) > Lake Khuvsgul (15 species) > lakes Kuanda-Chara (11 species). The burbot populations of the studied lakes form two large groups according to the results of cluster analysis of species composition of the parasite fauna. The first group includes the host populations of Tsipo-Tsipikan and Kuanda-Chara lakes, the second one combines the burbot populations of the bays and estuaries of tributaries of the Lake Baikal and Lake Khuvsgul. The use of parasitological data in addition to molecular genetic and paleontological information brings new arguments to the discussion about the evolutionary history of burbot.

Keywords: fauna of parasites, burbot, Lake Baikal, Baikal rift zone, Lake Khuvsgul, Tsipo-Tsipikan lakes, Kuanda-Chara lakes.

The Distribution of Viruses in a Water Column of the Rybinsk Reservoir During the Ice-cover period and Their Role in Mortality of Heterotrophic Bacteria.

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: kopylov@ibiw.yaroslavl.ru

The abundance of virio- and bacterioplankton was determined in the pelagic and littoral zones of the Rybinsk reservoir during an ice-cover period, as well as the importance of viruses in the infection and mortality of heterotrophic bacterioplankton was evaluated. At the water temperature of 0.3–0.9° C the number of planktonic bacteria and viruses varied within (37.1–84.1) × 10⁶ (on average (57.3 ± 2.1) × 10⁶) particles/ml and (2.50–6.11) × 10⁶ (on average (3.66 ± 0.16) × 10⁶) cells/ml respectively. The ratio of viruses to bacteria numbers varied from 8.8 to 27.9 (on average 16.5 ± 0.7). Visible infected cells constituted 0.3–5.0% (on average 1.5 ± 0.2%) of the bacterioplankton abundance. The number of mature viral particles inside the infected bacterial cells ranged from 5 to 107 (on average 17 ± 4) particles/cell. Virus-induced mortality of bacteria averaged 13.0 ± 1.9% (within the range 2.0–55.0%) of their daily bacterial production. The data indicate the importance of viruses in the control of the bacterial abundance and production in the reservoir during the ice-cover period.

Keywords: planktonic viruses, heterotrophic bacteria, virus-induced mortality of bacteria, ice-cover period, Rybinsk reservoir.

The first data on the hepato- and neurotoxigenic cyanobacteria in phytoplankton of the Rybinsk Reservoir were obtained. Different methods of detection of toxigenic cyanobacteria (light microscopy, PCR analysis, enzyme-linked immunosorbent assay) showed similar results. Hepatotoxins microcystins and neurotoxins saxitoxins were detected in the reservoir, the presence of cylindrospermopsin and anatoxin-a was not identified. mcyE and stxA, genes which are responsible for the biosynthesis of microcystins and saxitoxins respectively, were found in the total phytoplankton DNA. The presence of mcyE gene-containing cyanobacteria of three genera: Microcystis (M. aeruginosa, M. viridis), Planktothrix (P. agardhii) and Dolichospermum (Anabaena), were identified. The hypothesis about the presence of saxitoxin-producing Dolichospermum (Anabaena) in the Rybinsk Reservoir was proposed.

Keywords: phytoplankton, cyanobacteria, microcystins, saxitoxins, cylindrospermopsin, anatoxin-a, mcyE, stxA, аоаА, anaC genes.

Strontium (Sr) and calcium (Ca) contents and Sr/Ca ratios in otoliths of walleye, Sander lucioperca were studied. The sample of 95 specimens from Lower Volga region was studied, the fish were obtained in the section of the Akhtuba River at the distance of 250–279 km upstream from the Caspian Sea. A part of specimens in the sample had low strontium content throughout the otolith. The other fish had increased both Sr content and Sr/Ca ratios in core zones of otolith or near its outer edge: the Sr/Ca ratio was over 6.00 · 10⁻³ with the maximum at 10.02 · 10⁻³. The fish with low Sr/Ca ratio live in a freshwater and demonstrate a resident life history strategy. The walleyes that had increased ratios of Sr/Ca in outer zones of otolith demonstrate a migratory life history strategy. Those fish leave freshwater of Volga and use a brackish water of Northern Caspian Sea. Some of migratory fish make outmigration to the sea at age of young-of-the-year, stay in a brackish water for one year or less and then return back to fresh water the rest of its life. The other migrate walleyes migrating back and forth from freshwater to the sea several times during their life. Finally, some fish leave freshwater for 1–2 years, staying full this time in the Northern Caspian Sea. The conclusion is that the walleye stock in the Lower Volga have a complicated composition and consists of freshwater (residents and reodromic ones) and migratory (anadromous and semi-anadromous) fish.

pH-values in the intestines of nine fish species from Lake Chany (Western Siberia) were determined. Seasonal changes of pH values in the fish intestines were found. Intestinal pH-values decrease in summer as the temperature rises and increase during the cold season as the temperature drops. The hypothesis was advanced that temperature-dependent pH changes in the intestine may serve as a regulatory mechanism keeping the activity of hydrolytic enzymes at the level required for successful digestive processes due to some adaptive modifications of the medium where these enzymes operate.

Keywords: freshwater teleosts, pH, digestive tract, temperature.

The Blood Proteins Variability in Sturgeon Ontogenesis and Possible Aspects of Evolution in the Family Acipenseridae.

Institute for Biology of Inland Waters RAS, 152742 Borok, Russia

e-mail: smif@ibiw.yaroslavl.ru

The developmental changes in sturgeon blood proteins of three genera Acipenser, Huso and Pseudoscaphirhynchus belonging to the family Acipenseridae were studied by immunological methods. Heterochronicity and stages of development in proteins were determined. The proteins that define the specificity of immunoelectrophoregrams and change little with the fish growth are formed first. The formation of transferrins is completed in the latest turn. Patterns of development are independent on the ecology of the various forms of sturgeon that results in the same type of immunoelectrophoregrams of blood proteins in adult individuals of ten fish species. It is supposed that the blood proteins variability in ontogenesis of sturgeons reflects the evolution of this fish through consecutive adaptation to sea water of different salinity and transition of ancestors to anadromous life history in oceanic salinity. Probably, modern potamodromous sturgeons were formed as a result of the return of anadromous forms to life in fresh water.

Keywords: antigens, blood proteins, transferrins, immunoelectrophoresis, sturgeons, ontogeny, evolution.

The levels of metals and toxicity in sediments of aquatic systems of Central and South Vietnam were determined. It was defected that the concentration of metals (As, Cr, Cu, Hg, Ni, Pb, Zn) exceeded the Clarke number of the Earth's crust that may be associated with geochemical peculiarities of the province. Acute toxicity of sediments elutriate for Ceriodaphnia and whole sediments for larvae of chironomids was not registered at all investigated reservoirs. The increase in relative abundance of Ch. riparius larvae with deformation of mouthparts structures compared to control was observed for the most of aquatic ecosystems. This index reaches the maximum value in the Khe river (Kantho province). Antennas anomalies dominated in pathological disorders.

Keywords: sediments, toxicity, heavy metals, Vietnam.
