Production of EPA and DHA in aquatic ecosystems and their transfer to the land / M. I. Gladyshev, N. N. Sushchik, O. N. Makhutova // Prostaglandins and Other Lipid Mediators. - 2013, DOI 10.1016/j.prostaglandins.2013.03.002 . - ISSN 1098-8823

Aquatic ecosystems -- Docosahexaenoic acid -- Eicosapentaenoic acid -- Trophic transfer efficiency
Аннотация: Most omnivorous animals, including humans, have to some degree relied on physiologically important polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from food. Only some taxa of microalgae, rather than higher plants can synthesize de novo high amounts of EPA and DHA. Once synthesized by microalgae, PUFA are transferred through trophic chain to organisms of higher levels. Thus, aquatic ecosystems play the unique role in the Biosphere as the principal source of EPA and DHA for most omnivorous animals, including inhabitants of terrestrial ecosystems. PUFA are transferred from aquatic to terrestrial ecosystems through riparian predators, drift of carrion and seaweeds, emergence of amphibiotic insects, and water birds. The essential PUFA are transferred through trophic chains with about twice higher efficiency than bulk carbon. Thereby, PUFA are accumulated, rather than diluted in biomass of organisms of higher trophic levels, e.g., in fish. Mankind is faced with a severe deficiency of EPA and DHA in diet. Although additional sources of PUFA supply for humans, such as aquaculture, biotechnology of microorganisms and transgenic terrestrial oil-seed producing plants are developed, natural fish production of aquatic ecosystems will remain one of the main sources of EPA and DHA for humans. Aquatic ecosystems have to be protected from anthropogenic impacts, such as eutrophication, pollution and warming, which reduce PUFA production. В© 2013 Elsevier Inc. All rights reserved.

Аннотация: Abstract: Fatty acid composition and content of 2 forms of sockeye salmon Oncorhynchus nerka from lakes in Kamchatka Peninsula (Russia) were compared. One form of sockeye salmon was anadromous ("marine"), that is, adult fish migrated in ocean to feed and grow and than return in the lake to breed. Fish of another form, kokanee, never migrate in the ocean. Per cent levels of the main indicators of nutritive value, eicosapentaenoic acid (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3), were significantly higher in the landlocked O. nerka. However, concentrations of EPA and DHA per wet weight of filets were higher in the marine form, because of the relatively higher content of sum of fatty acids in their muscle tissue. As concluded, fish fed in marine environment had higher contents of long-chain n-3 fatty acids per wet weight than fish of the same species, fed in fresh waters. In general, both the anadromous sockeye salmon and the landlocked kokanee salmon can be recommended for human diet as a valuable product concerning contents of EPA and DHA.

Аннотация: In the course of monthly sampling in 2008-2010, two regions of the littoral of the Yenisei river were compared. One of these regions (conventionally pure) was situated upstream of Krasnoyarsk, while the other (conventionally polluted) was downstream of Krasnoyarsk. The concentrations of heavy metals, oil products, phenols, biogenic elements and essential polyunsaturated fatty acids (PUFAs) in various components of the river ecosystem were determined. It was discovered that the anthropogenic pollution causes a decrease in the resources of essential PUFA in the biomass of the upper links of the food chain of the river ecosystem.

Effect of temperature on contents of essential highly unsaturated fatty acids in freshwater zooplankton / M. I. Gladyshev [et al.] // Limnologica. - 2011. - Vol. 41, Is. 4. - P339-347, DOI 10.1016/j.limno.2011.03.001 . - ISSN 0075-9511

Аннотация: In 11 lakes from cold and warm regions we studied the content of highly unsaturated fatty acids (HUFA) in seston (<130?m) and crustacean zooplankton using gas chromatography-mass spectrometry. An increase of temperature correlated with a decrease of HUFA content in zooplankton. A multivariate canonical correlation analyses revealed, that the decrease of HUFA content was related with a decrease of per cent of copepods in zooplankton communities, which are known to have higher HUFA levels in their biomass, than cladocerans. This means that temperature primarily affected the HUFA levels indirectly, via changing of taxonomic structure of zooplankton community, while the homeoviscous adaptation of zooplankton individuals had comparatively lower importance. As found, water temperature was better predictor of HUFA contents of zooplankton, than the fatty acid composition of seston. Thus, it can be predicted, that a probable climate warming will decrease the content of the essential HUFA in freshwater zooplankton with possible negative consequences for animals of higher trophic levels.

Is the fatty acid composition of freshwater zoobenthic invertebrates controlled by phylogenetic or trophic factors? / O. N. Makhutova [et al.] // Lipids. - 2011. - Vol. 46, Is. 8. - P709-721, DOI 10.1007/s11745-011-3566-9 . - ISSN 0024-4201

Аннотация: We studied the fatty acid (FA) content and composition of ten zoobenthic species of several taxonomic groups from different freshwater bodies. Special attention was paid to essential polyunsaturated fatty acids, eicosapentaenoic acid (EPA, 20:5n-3), docosahexaenoic acid (DHA, 22:6n-3), and arachidonic acid (ARA, 20:4n-6); and the n-3/n-6 and DHA/ARA ratios, which are important for consumers of higher trophic levels, i.e., fish. The content and ratios of these FA varied significantly in the studied zoobenthic species, consequently, the invertebrates were of different nutritional quality for fish. Eulimnogammarus viridis (Crustacea) and Dendrocoelopsis sp. (Turbellaria) had the highest nutrition value for fish concerning the content of EPA and DHA and n-3/n-6 and DHA/ARA ratios. Using canonical correspondence analysis we compared the FA profiles of species of the studied taxa taking into account their feeding strategies and habitats. We gained evidence that feeding strategy is of importance to determine fatty acid profiles of zoobenthic species. However, the phylogenetic position of the zoobenthic species is also responsible and may result in a similar fatty acid composition even if species or populations inhabit different water bodies or have different feeding strategies.

Small lake plankton and its essential polyunsaturated fatty acids content as affected by a colony of the common heron (Ardea cinerea L.) / A. V. Krylov [et al.] // Contemporary Problems of Ecology. - 2011. - Vol. 4, Is. 1. - P42-49, DOI 10.1134/S1995425511010073 . - ISSN 1995-4255

Аннотация: It is shown that in the area inhabited by a colony of the common heron in a high-trophic shallow lake a number of structure parameters of plankton undergoes changes similar to those observed at anthropogenic eutrophication and indicating an increase in biogenic and organic load. At the same time a number of changes is revealed that are usually not registered when human influence increases. The composition and content of polyunsaturated fatty acids in seston and zooplankton show that diatoms and detritus of land genesis play relatively smaller role in the zooplankton nutrition in the lake area influenced by the birds. The zooplankton developing in this zone is a better food rich in essential docosahexaenoic acid necessary for the growth and development of the fish. В© 2011 Pleiades Publishing, Ltd.

Efficiency of transfer of essential polyunsaturated fatty acids versus organic carbon from producers to consumers in a eutrophic reservoir / M. I. Gladyshev [et al.] // Oecologia. - 2011. - Vol. 165, Is. 2. - P521-531, DOI 10.1007/s00442-010-1843-6 . - ISSN 0029-8549

Аннотация: One of the central paradigms of ecology is that only about 10% of organic carbon production of one trophic level is incorporated into new biomass of organisms of the next trophic level. Many of energy-yielding compounds of carbon are designated as 'essential', because they cannot be synthesized de novo by consumers and must be obtained with food, while they play important structural and regulatory functions. The question arises: are the essential compounds transferred through trophic chains with the same efficiency as bulk carbon? To answer this question, we measured gross primary production of phytoplankton and secondary production of zooplankton and content of organic carbon and essential polyunsaturated fatty acids of ?-3 family with 18-22 carbon atoms (PUFA) in the biomass of phytoplankton and zooplankton in a small eutrophic reservoir during two summers. Transfer efficiency between the two trophic levels, phytoplankton (producers) and zooplankton (consumers), was calculated as ratio of the primary production versus the secondary (zooplankton) production for both carbon and PUFA. We found that the essential PUFA were transferred from the producers to the primary consumers with about twice higher efficiency than bulk carbon. In contrast, polyunsaturated fatty acids with 16 carbon atoms, which are synthesized exclusively by phytoplankton, but are not essential for animals, had significantly lower transfer efficiency than both bulk carbon, and essential PUFA. Thus, the trophic pyramid concept, which implicitly implies that all the energy-yielding compounds of carbon are transferred from one trophic level to the next with the same efficiency of about on average 10%, should be specified for different carbon compounds.

Seasonal distribution and fatty acid composition of littoral microalgae in the Yenisei River / N. N. Sushchik [et al.] // Journal of Applied Phycology. - 2010. - Vol. 22, Is. 1. - P11-24, DOI 10.1007/s10811-009-9418-9 . - ISSN 0921-8971

Аннотация: We studied fatty acid (FA) composition of littoral microalgae in the fast-flowing oligotrophic river, the Yenisei, Siberia, monthly for 3 years. Seasonal dynamics of species composition had similar patterns in all the studied years. In springs, a pronounced dominance of filamentous green algae occurred, in summer and autumn diatoms were abundant, and in late autumn and winter epilithic biofilms consisted primarily of cyanobacteria and detritus. In general, FA composition of the algal periphytic community was dominated by 16:0, 16:1?7, 20:5?3, 14:0, and 18:3?3 throughout the studied period. Several groups of FAs, which had peculiar seasonal dynamics, were differentiated by statistical analysis based on a method of correlation graphs. The seasonal changes in FA composition could be partly explained by the seasonal succession of species composition of the community. Besides, we found that populations of both diatom and green algae grown in summer at a higher water temperature were lower in polyunsaturated fatty acids than those in spring, at a lower temperature. Hence, we suppose that the regular seasonal dynamics of FA composition of the studied littoral microalgae was driven both by changes in species composition and by temperature adaptations of the algal populations. The highest content of essential polyunsaturated FAs, eicosapentaenoic and docosahexaenoic acids, in the spring "psychrophilic" populations of diatoms could make them of the higher nutritive value for zoobenthic primary consumers.

Seasonal dynamics of fatty acids in the lipids of water moss Fontinalis antipyretica from the Yenisei River / G. S. Kalacheva [et al.] // Russian Journal of Plant Physiology. - 2009. - Vol. 56, Is. 6. - P795-807, DOI 10.1134/S1021443709060090 . - ISSN 1021-4437

Аннотация: Identification of lipid fatty acids (FA) and studying of their seasonal dynamics in water moss Fontinalis antipyretica from the Yenisei River were carried out by means of gas chromatography-mass spectrometry. FA composition of water moss was notable for a relatively low level of saturated acids and predominance of polyunsaturated acids (PUFA) with double bonds (accounting for more than 30% of total FA) and polyunsaturated acids with double and triple bonds (acetylenic acids, accounting for more than 40% of total FA). Among PUFA, ?- and ?-linolenic (18:3?3 and 18:3?6), arachidonic (20:4?6), and eicosapentaenoic (20:5?3) acids prevailed. Relative content of PUFA from ?3-family was the greatest in spring, and the level of PUFA from ?6-group was essentially the same throughout all the seasons. In the biomass of water moss, we identified seven acetylenic acids; among them octadeca-9,12-dien-6-ynoic (6a,9,12-18:3), octadeca-9,12,15-trien-6-ynoic (6a,9,12,15-18:4), and eicosa-11,14-dien-8-ynoic (8a,11,14-20:3) acids were predominant. For the first time, in the lipids of water moss we identified an acetylenic eicosa-11,14,17-trien-8-ynoic acid (8a,11,14,15-20:4). Relative content of acetylenic acids in the total FA was great throughout the entire period of investigation with the peak accumulation in summer. Owing to a steadily high level in the biomass of water moss and the lack of other producers of these acids in the ecosystem, acetylenic FA are highly specific biochemical markers useful for the investigation of trophic interactions between higher aquatic plants and zoobenthos.

Аннотация: Three canned fish species - Pacific saury (Cololabis saira), Pacific herring (Clupea harengus) and Baltic sprat (Sprattus sprattus) - most common and popular in Russia, were analyzed for fatty acids. Special attention was paid to long-chain essential polyunsaturated fatty acids: eicosapentaenoic acid (20:5?3) and docosahexaenoic acid (22:6?3). Sums of eicosapentaenoic acid and docosahexaenoic acid in saury, herring and sprat were, on average, 2.42, 1.80 and 1.43 g/100 g product, respectively. Contents of these essential acids in all the canned fish species were found to be very high compared with many other fish reported in the available literature. All the canned fish appeared to be highly valuable products for human nutrition concerning the content of eicosapentaenoic and docosahexaenoic acids.

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: Frozen samples of common fish species, sea trout (Salmo trutta), from Norway and Siberia, herring (Clupea harengus pallasi), rock sole (Lepidopsetta bilineata) and cod (Gadus morhua maris-albi), collected from a wholesale market in Krasnoyarsk city (Siberia, Russia) were analyzed. Special attention was paid to long-chain essential polyunsaturated fatty acids: eicosapentaenoic, 20:5?3 (EPA) and docosahexaenoic, 22:6?3 (DHA). Heat-treatment (cooking and frying) did not in general significantly decrease the contents of EPA and DHA compared to raw fish species, except for a modest reduction in Norwegian trout during frying. Boiled trout appeared to be a more valuable fish dish for obtaining the officially recommended appropriate daily intake of EPA + DHA for humans. Herring and sole had intermediate values, while boiled cod had a comparatively low value. В© 2006 Elsevier Ltd. All rights reserved.

Аннотация: We studied composition and concentrations of fatty acids (FAs) in benthos from pebbly littoral region of the Yenisei River in a sampling site near Krasnoyarsk city (Siberia, Russia) for 1 year from March 2003 to February 2004. Special attention was paid to major long-chain polyunsaturated fatty acids (PUFAs) of the ?3 family: eicosapentaenoic acid (EPA, 20:5?3) and docosahexaenoic acids (DHA, 22:6?3). In phytobenthos, which was dominated by diatoms, the annual maxima of EPA and DHA pool occurred in spring and early summer. In zoobenthos, EPA and DHA pool peaked in autumn, due mainly to an increase of the biomass of dominant taxa (gammarids) and to a moderate increase of the PUFA content per body weight. Seasonal peaks of EPA in overwintering insect larvae (chironomids and caddisflies) generally coincided with those of biomass of these larvae, while there was no such trend for amphipods and oligochaetes. In spring and early summer, the main part of ?3 PUFA, 40-97% of total amount, in the littoral region was contained in biomass of producers, i.e., benthic microalgae, and in autumn it was transferred to primary consumers-benthic invertebrates, which contained ?76-93% of total ?3 PUFAs.

Аннотация: Seasonal variations of fatty acid contents in muscle tissue of one of the main food fish species in Siberian rivers, grayling, Thymallus arcticus, were studied over 3 years. Under a comparatively low range of water temperature variations, spawning appeared to be the main cause of seasonal changes in contents of quantitatively prominent and essential fatty acids in fish filets. In general, fish accumulated essential polyunsaturated fatty acids (PUFA), such as eicosapentaenoic (EPA) and docosahexaenoic (DHA), in their muscle tissue before reproductive seasons and then the PUFA seemed to be transferred into gonads during their formation. Hard roe of Siberian grayling had 3-4 times higher PUFA contents, than had that of the muscle tissue. The fish species, T. arcticus, was found to be a valuable source of the essential PUFA, including EPA and DHA, for human diet. В© 2007 Elsevier Ltd. All rights reserved.

Seasonal correlations of elemental and ?3 PUFA composition of seston and dominant phytoplankton species in a eutrophic Siberian Reservoir / M. I. Gladyshev [et al.] // Aquatic Ecology. - 2007. - Vol. 41, Is. 1. - P9-23, DOI 10.1007/s10452-006-9040-8 . - ISSN 1386-2588

Аннотация: The elemental and fatty acid composition of seston was studied for 3 years, from May to October, in a small Reservoir. Under comparatively low C:P ratio, multivariate canonical analysis revealed no straightforward simple correlations between phosphorus and single ?3 PUFA species, but complex significant interaction between elemental composition (stoichiometry) of seston and total sestonic ?3 PUFA as a whole. Since sestonic C, P and N were found to originate mostly from phytoplankton, the contents of particulate elements and PUFA were attributed to single species in periods of their pronounced dominance. Phytoplankton species of genera of Stephanodiscus, Peridinium, Gomphosphaeria, Planktothrix and Anabaena in periods of their pronounced dominance had relatively constant species-specific elemental and PUFA composition. Phytoplankton species significantly differed in their elemental and PUFA composition, as well as in ratios of C:N, N:P, PUFA:P and partly C:P that indicate food quality for zooplankton. Hence, there were no phytoplankton species of clearly high or low nutritional value. All of phytoplankters, or at least detritus, that originated from them, may meet specific elemental and biochemical requirements of specific groups of zooplankton. Dividing phytoplankton on basis of their elemental and biochemical composition, i.e., nutrition quality, into large taxa (cyanobacteria, diatoms, etc.) appeared to be too coarse for assessing nutritional value for zooplankton.

Аннотация: Seasonal dynamics of contents of essential polyunsaturated fatty acids (PUFA) in dominant groups of benthic invertebrates: gammarids (Gammaridae, Amphipoda), oligochaetes (Oligochaeta), chironomid larvae (Chironomidae, Diptera) and caddisfly larvae (Trichoptera), and dominant benthivorous fish, Siberian grayling Thymallus arcticus, have been studied in ecosystem of the large Siberian river. During the year of the study most benthic invertebrate taxa showed significant variations in the contents of both C-18 and long chain C-20-22 PUFAs. In contrast, the fish, which consumed the zoobenthos, had no significant seasonal variations in long chain PUFAs' contents. Thereby, the fish, as organisms of relatively higher evolution level than invertebrates, was supposed to have more strict metabolic control of long chain PUFAs' contents. Evidence was obtained that the studied fish species, grayling, may be capable to convert dietary EPA into DHA. В© 2006 Elsevier Inc. All rights reserved.
