“…The results obtained in the present work reveal that these major and minor fatty acids coincided with other studies, and the fatty acid profile conformed to the common pattern of bivalves in general [7][8][9][10][11]. The quantity of C16:0, which is key component in biosynthesis of fatty acids, varies over a wide range in marine and freshwater molluscs [12].…”

“…C16:1ω7 is believed to be a diatom marker, whereas C18:1ω9 is not restricted to a single phytoplankton group. C18:4ω3 and C16:4ω3 (not detected in the current study) were determined as minor components in phytoplankton samples [11]. It is wise to express that the diet of A. piscinalis and C. fluminalis mostly contained diatoms and some flagellates.…”

“…In contrast with most of detailed studies on biochemical and physiological composition of marine bivalves [4][5][6][7][8][9][10][11][12][13][14], there are a few studies on freshwater species. Diplodom patagonicus [15], Diplodon delodontus [16], Carunculina texasensis [17], Dreissena polymorpha [18], Dreissena siouffi [19] and Unio elongatulus [20] are some of the studied freshwater mussels.…”

Purpose: The aim of this work was to investigate quantitative and qualitative fatty acid composition of phospholipid, monoacylglycerol, diacylglycerol, triacylglycerol and total body lipid of two adult freshwater mussels, Anodonta piscinalis (Nilsson, 1822) and Corbicula fluminalis (Müller, 1774). Methods: Mussels' body lipids were fractionated by thin layer chromatography. Gas chromatography and gas chromatography-mass spectrometry instruments were used to detect the fatty acids. Results: C16:0, C18:0, C16:1ω7, C18:1ω9, C18:2ω6 and C20:4ω6 were the dominant fatty acids. Their total percentages are between 70.37% and 82.11% in A. piscinalis and between 66.70% and 75.53% in C. fluminalis. As characteristic to freshwater mussels, Σω6 / Σω3 ratio was defined high in all lipid fractions. In both of the mussels, the maximum level of total polyunsaturated fatty acids was found in the phospholipids, and the maximum level of the total saturated fatty acids was found in the monoacylglycerol fractions. However, the level total monounsaturated fatty acids showed differentiations among fractions. In comparison to other fractions, the phospholipid contained high amount of C20:4ω6 and C20:5ω3, involved in eicosanoids formation. Conclusion:The study provided insight into the biochemistry and nutritional value of the widely distributed freshwater mussels from Tigris River. Key words: fatty acids, Anodonta piscinalis, Corbicula fluminalis, freshwater mussel, Tigris River Conflict of interest: Authors have no conflict of interest. ÖZETAmaç: Bu çalışmanın amacı, tatlısu midyesi Anodonta piscinalis (Nilsson, 1822) ve Corbicula fluminalis (Müller, 1774)'in fosfolipit, monoaçilgliserol, diaçilgliserol, triaçilgliserol ve total vücut lipidinin yağ asidi içeriğini kalitatif ve kantitatif olarak araştırmaktır. Metotlar: Midyelerin total vücut lipitleri, ince tabaka kromatografi ile fraksiyonlandı. Yağ asidi içeriği, gaz kromatografi ve gaz kromatografi-kütle spektrometre cihazları kullanılarak tespit edildi. Bulgular: C16:0, C18:0, C16:1ω7, C18:1ω9, C18:2ω6 ve C20:4ω6 asitler çoğunlukta bulunan bileşenlerdi. Toplam oranları A. piscinalis'te %70.37 ve %82.11 arasında; C. fluminalis'te ise %66.70 ve %75.53 arasında değişti. Tatlısu midyelerine özgü olduğu gibi, Σω6 / Σω3 değeri tüm fraksiyonlarda yüksek miktarda bulundu. Her iki midye türünde de en yüksek total çoklu doymamış yağ asidi oranı, fosfolipitte; en yüksek total doymuş yağ asidi oranı ise monoaçilgliserolda saptandı. Total tekli doymamış yağ asidi oranı ise fraksiyonlar arasında farklılık gösterdi. Diğer fraksiyonlar ile kıyaslanınca, fosfolipit fraksiyonunda eikosanoidlerin yapımında görev alan C20:4ω6 ve C20:5ω3 asitler daha yüksek oranda bulundu. Sonuç: Çalışma, Dicle Nehri'nde geniş dağılış gösteren tatlısu midyelerinin besinsel ve biyokimyasal özelliklerine ait bilgiler sağlamıştır. Anahtar kelimeler: yağ asitleri, Anodonta piscinalis, Corbicula fluminalis, tatlısu midyesi, Dicle Nehri Çıkar çatışması: Yazarların çıkar çatışması yoktur.

“…Кроме того, в триацил-глицеринах корма «Coraliquid», в отличие от сестона, отмечалось повышенное содержа-ние МНЖК -20:1n-11 и 20:1n-9. Вместе с тем в жирнокислотном спектре сестона Белого моря отмечалось преобладание полиненасы-щенных жирных кислот (ПНЖК) n-3 семейства (18:4, 20:4, 20:5, 22:5 и 22:6) и n-6 семейства (20:2, 20:3, 22:3, 22:4 и 22:5), которые, как из-вестно, поступают моллюскам в составе фито-планктона Alkanani et al, 2007].…”

“…Как известно, у Bivalvia синтез поли-ненасыщенных жирных кислот (ПНЖК) ограни-чен или невозможен Zhukova et al, 1998], они получают эти кислоты с пищей (т. е. в составе сестона). Более того, жирно-кислотный спектр двустворчатых фильтрующих моллюсков, как и всех консументов, служит трофическим маркером, отражающим состав их пищи, и включает в себя биохимические мар-керы всех компонентов сестона, в частности фитопланктона, зоопланктона и бактерий (де-трита) Alkanani et al, 2007].…”

Food availability is a key regulator of the distribution, metabolism, and success of benthic populations. In deep sea ecosystems, hydrodynamics and depth play fundamental roles in determining benthic food resources. Recent studies suggest that the Southern Ocean sub‐Antarctic front is shifting southward, with implications for primary production and food availability around the sub‐Antarctic Islands embedded in the Antarctic Circumpolar Current. We used fatty acid (FA) and stable isotope (SI) analyses to investigate the trophic pattern of benthic invertebrates and suspended particulate matter (SPM) at three Depths (shallow: 100 m, middle: 300 m, and deep: 600 m) in three hydrographic regions with different flow and productivity regimes around the Prince Edward Islands. Both region and depth affected the SI values of SPM, while feeding guild was the key factor influencing consumer trophic values. Depth affected the δ15N of all trophic groups and the FA compositions of suspension feeders. Deeper samples had a higher δ15N and showed a greater proportion of mono‐ and saturated fatty acids, reflecting greater remineralization of SPM and of food reaching the seafloor. Region affected the δ13C and FA values of SPM, suspension feeders and deposit feeder/scavengers, with differences between the interisland and open ocean regions. This was probably linked to the retention of nutrients and phytoplankton between the islands. Critically, the effects of depth and hydrographic region were taxon specific, indicating that long‐term responses to environmental change may have complex consequences for the feeding ecology and viability of benthic populations, with implications for the higher trophic levels that these populations support.
