Ключевые слова (''Своб.индексиров.''): fatty acid composition--freshwater reservoir--gammarus lacustris--gut content--saline lake--sediments--seston
Аннотация: We studied fatty acid (FA) composition in samples from bodies and intestinal contents of the littoral amphipod Gammarus lacustris Sars, from the Bugach freshwater reservoir. Simultaneously, samples of seston and bottom sediments were also collected from the reservoir during early August. There were no differences in FA composition of gut contents, seston and sediments of pebbly bottom. Seston was the main food source of Gammarus but some FAs Gammarus got from sediments. The FA composition of G. lacustris and seston from the Bugach freshwater reservoir were compared with those of the animals from the saltwater Lake Shira (Siberia). While FA composition of the two Gammarus populations differed significantly, those of seston were practically similar: the composition of long-chain unsaturated fatty acids, 20:5omega3, 22:6omega3 and 20:4omega6, were significantly higher in animals from saline Shira Lake, whereas 16:1 and 16:0 were higher in the freshwater populations of amphipods from the Bugach freshwater reservoir. Taking into account the relevant literature data, we hypothesise that this difference in C16 acid might be a distinguishing characteristic of FA composition of freshwater and saltwater crustaceans.

METABARCODING APPROACH
RAPID ASSESSMENT
Аннотация: Conservation and sustainable management of aquatic ecosystems is a priority in environmental programs worldwide. However, these aims are highly dependent on the efficiency, accuracy and cost of existent methods for the detection of keystone species and monitoring of biological communities. Rapid advances in eDNA, barcoding and metabarcoding promoted by high-throughput sequencing technologies are generating millions of sequences in a fast way, with a promising cost reduction, and overcoming some difficulties of the traditional taxonomic approaches. This paper provides an updated broad perspective of the current developments in this dynamic field presented in the special session (SS) "The use of molecular tools in ecological and biodiversity assessment of aquatic ecosystems" of the XIX Congress of the Iberian Association of Limnology (AIL2018), held in Coimbra, Portugal. Developments presented are mainly focused on the Iberian Peninsula (Portugal and Spain, including Atlantic Macaronesian islands) but include studies in France, Germany, Finland, Russia (Siberia) and South America. The networks within which these researchers are involved are yet even broader, profiting from existing molecular facilities, and traditional taxonomic expertise, which can be viewed as a characteristic of this new research area. It was evident in the SS that the use of molecular tools is widespread, being used to study a diversity of aquatic systems, from rivers' headwaters to estuaries and coastal lagoons, and volcanic, mountain and frozen lakes to hot springs. The organisms targeted are likewise varied and include fish, macroinvertebrates, meiofauna, microalgae such as diatoms and dinoflagellates, other protists, fungi, and bacteria (cyanobacteria and other). Some studies address the whole biodiversity (i.e., all species present independently of the taxonomic group) from environmental samples of water, biofilms and preservative solution from field samples (e.g., ethanol from macroinvertebrate samples). Great advances were acknowledged in the special session, namely in the use of metabarcoding for detecting hidden biodiversity, juvenile stages, low-abundance species, non-indigenous species and toxicity potential, and ultimately for ecological monitoring of diatoms and invertebrates. Yet, several drawbacks were highlighted and need further work, which include: taxonomic gaps in the reference databases (including gaps at species level and on intraspecific variability) or absence of public databases (e.g. for meiofauna), still high sequencing costs, the need of a substantial bioinformatics effort, difficulties in establishing the amount of environmental sample necessary for a good DNA extraction and the need for testing different genetic markers to obtain accurate results.

Заглавие : Amino acid composition of epilithic biofilm and benthic animals in a large Siberian river
Место публикации : Freshwater Biology. - 2013. - Vol. 58, Is. 10. - С. 2180-2195. - ISSN 00465070 (ISSN) , DOI 10.1111/fwb.12200
Ключевые слова (''Своб.индексиров.''): amino acids--epilithic microalgae and cyanobacteria--nutritive quality--river ecosystem--zoobenthos
Аннотация: We studied amino acid (AA) composition of epilithic biofilms and zoobenthos near the shore at a middle section of the Yenisei River (Siberia, Russia). We hypothesised that there was an imbalance between the composition and content of amino acids in the biofilm and its consumers, the zoobenthos, as well as between those in the zoobenthos and fish. Based on monthly sampling from 2007 to 2010, there was seasonal variation in AA profiles in the epilithic biofilms, probably caused by the succession of microalgal and cyanobacterial species. Overall, there was an imbalance in the percentage of the essential amino acids (lysine and histidine) between benthic animals and their food (the epilithic biofilm), which suggests that benthic animals may be limited by food quality. Moreover, the zoobenthos had a significantly higher content of AA, relative to carbon, than the biofilm. Based on sampling in 2012, there was an imbalance between the AA profiles of zoobenthos and that of their main consumer, the Siberian grayling (Thymallus arcticus), particularly in the percentages of two essential amino acids, lysine and leucine. In terms of overall content of essential amino acids, the nutritional value to fish of gammarids, which have recently invaded the river, was significantly lower than that of indigenous taxa, trichopteran and chironomid larvae.

Заглавие : Amino acids in prospective feeds for fish aquaculture: A review of experimental data
Место публикации : J. Sib. Fed. Univ. - Biol.: Siberian Federal University, 2020. - Vol. 13, Is. 4. - С. 424-442. - ISSN 19971389 (ISSN), DOI 10.17516/1997-1389-0332
Аннотация: Total dependence of aquaculture on imports of feeds can significantly compromise Russia's food supply security; hence the task of designing new domestic feeds is of primary importance. A major challenge of world aquaculture is providing fish with a balanced diet, in particular, with a well-balanced composition of amino acids. In this review, we analyze international publications on the composition of amino acids in fish feed over the last two years. We summarize the data on the amino acid composition of prospective food sources for fish aquaculture: agricultural crops, insects, annelids, higher crustaceans, animal waste, phytoplankton, zooplankton, macrophytes, and microorganisms. We performed a comparative analysis of the composition of amino acids in promising aquafeed sources and fish flour traditionally used for fish feeding. Based on the results, we conclude that each of the examined food sources can be used as a component of fish nutrition and offers realistic prospects for production of alternative feeds. To ensure high quality of fish aquaculture products, the priority should be given to development of technologies which allow to control amino acid feed composition during the production process with respect to fish species-specific needs. It is hoped that this review will be useful to researchers and practitioners involved in designing and producing new domestic aquafeed for fish. © Siberian Federal University. All rights reserved.

Ключевые слова (''Своб.индексиров.''): anoxic hypolimnion--solar radiation--stratified lake--vertical migration--zooplankton
Аннотация: Two-section enclosures were designed for the investigation of the effect of various physicochemical and biological factors on vertical distribution of zooplankton in situ. The framework of the enclosure was a cylindrical polyethylene column without any partitions inside, in which the isolation of animals in different sections after in situ exposure was achieved by pinching the flexible central part of the column. Enclosures were tested at the brackish stratified meromictic Lake Shira (Russia, Khakasia). The absence of fish and carnivorous zooplankton in the lake suggests that the vertical distribution of zooplankton is mainly determined by physicochemical gradients in the water column. Experiments and field observations demonstrated that all age and size groups of Arctodiaptomus salinus and Brachionus plicatilis strongly avoided surface layers during the daylight. The escape of zooplankton from the anoxic hypolimnion was less active. Statistically significant avoidance was observed only for copepodites C4-C5 and females of A. salinus. The relatively simple construction of the columns and easy handling during the experiment were the factors that favoured the use of this device to perform in situ basic tests of the effect of different factors on the vertical distribution of zooplankton.

Заглавие : Artificial radionuclides in fish fauna of the Yenisei River in the vicinity of the Mining-and-Chemical Combine (Siberia, Russia)
Место публикации : Radioprotection. - 2011. - Vol. 46, Is. 6 SUPPL. - С. S75-S78. - ISSN 00338451 (ISSN) , DOI 10.1051/radiopro/20116649s
Аннотация: Activities of radionuclides were measured in five species of fish (grayling, dace, crucian carp, pike, cod) sampled in the Yenisei River (Siberia, Russia) in the vicinity of the Mining-and-Chemical Combine (ROSATOM) from 2007 to 2010, with a gamma-spectrometer (Canberra, USA). The analyses of samples of organs and tissues of fish species revealed artificial (46Sc, 51Cr, 54Mn, 58,60Co, 59Fe, 65Zn, 85Sr, 99Mo, 103,106Ru, 137Cs, 141,144Ce) and natural (7Be, 40K) radionuclides in fish organs and tissues, including edible ones. The major percent (up to 80%) of 137Cs and 40K activity occurred in muscles of fish species, which also contained considerable percentages of 60Co (up to 70%) and 65Zn (up to 20%). Seasonal changes in the intake of artificial radionuclides by zoobenthos-feeding fish species (grayling and dace) were recorded and they were followed by an activity concentration increase in internal organs. The dramatic increase in radionuclide intake by grayling coincided with the change of diet source. Hence, the feeding behavior of fish can change the fluxes of artificial radionuclides in the Yenisei River. The most effective diet transfer of a radionuclide from gammarus to grayling (muscles and total body) was recorded for 40K (1.3) and much less effective for artificial nuclides. В© 2011 EDP Sciences.

Ключевые слова (''Своб.индексиров.''): polyunsaturated fatty acids (pufa)--benefit-risk ratio--heavy metals--canned fish
Аннотация: Fatty acid (FA) and element contents were studied in 14 brands of canned (in its own juice and with sunflower oil) saury (Cololabis saira), a popular product of Russian market. Canned saury is a valuable source of essential polyunsaturated FA - eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3). To obtain personal daily dose of EPA + DHA of 1 g for prevention of cardiovascular diseases, neural and inflammatory disorders one needs to intake from 26 to 76 g of canned saury, as was calculated for studied brands. ICP-OES analysis of 24 elements showed that Pb concentration in one brand and Cd content in most of studied saury samples exceeded standards for fish meat established by the European Commission. However, values of hazard quotient, HQEFA, which estimate benefit -risk ratio of fish intake, indicate that canned saury is safe product for human nutrition. (C) 2016 Elsevier Ltd.

Заглавие : Benefit-risk ratio of food fish intake as the source of essential fatty acids vs. heavy metals: A case study of Siberian grayling from the Yenisei River
Место публикации : Food Chemistry. - 2009. - Vol. 115, Is. 2. - С. 545-550. - ISSN 03088146 (ISSN) , DOI 10.1016/j.foodchem.2008.12.062
Ключевые слова (''Своб.индексиров.''): benefit-risk ratio--essential fatty acids--grayling--hazard quotient--heavy metals
Аннотация: A formula was derived for quantification of benefit-risk ratio (hazard quotient) for the intake of a product containing essential polyunsaturated fatty acids vs. heavy metals. The quotient was used in a three year case study of the contents of essential fatty acids and heavy metals in Siberian grayling, the main food fish from the middle section of the Yenisei River. As found, in general the fish intake was potentially very beneficial for human health, except on a few occasions, when the risk overweighed the benefit because of high contents of chromium in the fish muscle tissue. The data demonstrated the necessity for regular monitoring of the hazard quotients for food fish in wild conditions, based at least on monthly sampling frequency. В© 2008 Elsevier Ltd.

Аннотация: The bioaccumulation of actinide Am-241 from food and water in bodies of freshwater fish (Carassius auratus gibelio, silver crucian carp) has been investigated in laboratory experiments. Homogenized biomass of submerged macrophytes labeled with Am-241 was injected into the fish gullet. Internal organs and tissues of crucian carp could be ranked according to activity concentration of dietary Am-241 after depuration of the digestive tract as follows: liver gonads bones muscles. Accumulation of waterborne Am-241 in internal organs and tissues of crucian carp mainly occurred via the digestive tract. While the concentration of Am-241 in liver of crucian carps decreased during depuration time, its concentration in bones increased indicating slower transfer of Am-241 to skeleton compared to muscles and liver. The retention of dietary Am-241 in the bodies of crucian carp reached 35%-46% of ingested Am-241: 20%-31% was retained in liver, 0.6%-0.8% in skeleton, and 1.4%-2.0% in muscles. The concentration factor of Am-241 from water was 0.4 for the whole body, 0.3 for liver, 0.01 for muscles, and 0.01 for skeleton. Trace amounts of Am-241 were recorded in viscera and muscles of a wild population of silver crucian carp inhabiting a radioactively contaminated part of the Yenisei River.

Аннотация: To create a life support system based on biological and physical-chemical processes is the optimum solution providing full-valued condidtions for existence and efficient work of people at a lunar base. Long-standing experinece in experimental research or closed ecosystems and their components allows us to suggest a realistic functional structure of the lunar base and to estimate qualitatively its parameters. The original restrictions are as follows: 1) the basic source of energy to support the biological processes has to be the solar radiation; 2) the initial amount of basic biological elelments forming the turnover of substances (C, O, H, P, K, N) has to be delivered from Earth; 3). Moon materials are not to be used in the biological turnover inside the base; 4) the base is to supply the crew fully with atmosphere and water, and with 90% (A scenario) or 40% (B scenario) of food. Experimental data about the plant productivity under the "Moon" rhythm of light and darkness allow us to suggest that the A scenario requires per one human: plant area - 40 m2 irradiated during the lunar day by 250-300 W/m2 PAR producing 1250 g of dry biomass a terrestrial day; a heterotrophic component of "biological incineration" of inedible plant biomass (800 g/day) including the aquaculture of fish to produce animal products and contaminating the environment less than birds and mammals, and the culture of edible mushrooms; a component of physical-chemical correction for the LSS envi ronment including the subsystems of: deep oxidation of organic impurities in the atmosphere and of water, organic wastes of human activity and that biological components (420 g/day) Co2 concentration in "Moon" nights, damping O2 in "Moon" days, etc. The stock of presotred or delivered from Earth substances (food additions, seeds, etc.) to be involved in biological turnover is to be about 50 kg/year per man. Increase of the mass of prestored substances per man up to 220 kg/year would reduce twice the plant area and consumed amount of radiant energy to exclude the components of "biological incineration" and physical-chemical destruction of organic wastes.

Аннотация: New results obtained in the detection of rhythms in the low frequency range in the light signal of a small number of photo bacteria are reported. The luminescence of a small number of bacteria was recorded with an apparatus the sensitivity of which was 12 quanta/pulse. To check the possible rhythms in the luminescence of the bacteria, correlation analysis was made of the interpulse intervals of the detection of the signal with a computer. This revealed a definite rhythm in the bacterial luminescence the fundamental frequency of which lies in the region 8 c/s. Profound modulation of a bioluminescent signal at this and multiple frequencies was demonstrated. The harmonic components found in the spectrum of the signal refute the existing view of the continuous character of bacterial luminescence.

Аннотация: The effect of a biotic factor-the presence of predatory fish in water-on the composition and content of fatty acids in crustaceans was studied in the populations of the lake amphipod Gammarus lacustris from two lakes with fish and three lakes without fish. It was found that, at an overall increase in the quantity and quality of food resources (namely, increase in the content of eicosapentaenoic acid and docosahexaenoic acid (DHA) in the biomass), the relative rate of DHA accumulation in gammarids in the lakes without fish is higher than in the lake with fish.

Аннотация: Three levels of chemical communications involved plankton Crustacea are considered: 1) Influence of zooplankton excretion on phytoplankton; 2) Influence of zooplankton excretion on the individuals of the same or other species of the same trophic level; 3) Influence of chemical cues released by predatory zooplankton and fish on herbivorous zooplankton. The data on the influence of excreted cues on some physiological (growth, reproduction, feeding, etc.) and behavioural (vertical and horizontal migrations) characters of planktonic crustaceans are presented. Ecological role and chemistry cues responsible for the interactions of different trophic levels can be different. It is considered that chemical communications in aquatic ecosystems can be provided with: 1) Species-specific cues that strictly influence particular biological functions (communication system of feromone type); 2) Non-specific cues that strictly influence particular functions (system of regulator, that act at the whole ecosystem as the hormonal system of an organism). 3) Non-specific substances with broad (nonspecific) influence-toxic substances of "biocondition substances" according to classification of Novikov and Kharlamova (2000).

Аннотация: Bioluminescence is a widespread natural phenomenon. Luminous organisms are found among bacteria, fungi, protozoa, coelenterates, worms, molluscs, insects, and fish. Studies on bioluminescent systems of various organisms have revealed an interesting feature - the mechanisms underlying visible light emission are considerably different in representatives of different taxa despite the same final result of this biochemical process. Among the several substrates of bioluminescent reactions identified in marine luminous organisms, the most commonly used are imidazopyrazinone derivatives such as coelenterazine and Cypridina luciferin. Although the substrate used is the same, bioluminescent proteins that catalyze light emitting reactions in taxonomically remote luminous organisms do not show similarity either in amino acid sequences or in spatial structures. In this review, we consider luciferases of various luminous organisms that use coelenterazine or Cypridina luciferin as a substrate, as well as modifications of these proteins that improve their physicochemical and bioluminescent properties and therefore their applicability in bioluminescence imaging in vivo. © 2015 Pleiades Publishing, Ltd.
