The proximate compositions and fatty acid profiles of the freshwater mussels Unio terminalis and Potamida littoralis were compared. The crude protein (11.87-11.97%), lipid (2.55-1.05%), ash (1.68-1.61%) and moisture (80.36-81.69%) contents of U. terminalis and P. littoralis were observed. Lipid content of U. terminalis was found to be significantly (P<0.05) higher than in P. littoralis. The percentages of total saturated fatty acids (SFA) and total monounsaturated fatty acids (PUFA) were higher in U. terminalis than in P. littoralis, whereas the corresponding total polyunsaturated fatty acids (MUFA) content was lower. The n3/n6 ratio of U. terminalis and P. littoralis were 1.54-1.40, respectively. The data obtained indicate that the % composition of n3 PUFAs is greater for U. terminalis. Both of these species are good sources of EPA and DHA. Therefore, it was concluded that freshwater mussels U. terminalis and P. littoralis are suitable as healthy food choice. Keywords: Unio terminalis, Potamida littoralis, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA). İki Tatlı Su Midyesinin Yenilebilir Kısımlarının Besin Kompozisyonu ve Yağ Asidi Profilleri ÖzetTatlı su midyesi Unio terminalis ve Potamida littoralis'in besin kompozisyonu ve yağ asidi profilleri karşılaştırılmıştır. U. terminalis ve P. littoralis'in ham protein (%11,87-11,97), lipit (%2,55-1,05), kül (%1,68-1,61) ve nem (%80,36-81,69) içerikleri incelenmiştir. U. terminalis'in lipit içeriği P. littoralis'inkine göre önemli ölçüde (P<0,05) yüksek bulunmuştur. U. terminalis'in toplam çoklu doymamış yağ asitleri (MUFA) içeriği P. littoralis'inkine oranla daha düşük iken; toplam doymuş yağ asidi (SFA) ve toplam tekli doymamış yağ asidi (PUFA) yüzdeleri daha yüksek bulunmuştur. U. terminalis ve P. littoralis'in n3/n6 oranları sırasıyla 1,54-1,40 olarak tespit edilmiştir. Bulgular, n3 PUFA yüzde kompozisyonunun U. terminalis için daha yüksek olduğunu göstermiştir. Her iki türün EPA ve DHA'nın iyi birer kaynağı olduğu tespit edilmiştir. Sonuçta, tatlı su midyeleri U. terminalis ve P. littoralis sağlıklı gıda seçenekleri olarak uygun bulunmuştur.Anahtar Kelimeler: Unio terminalis, Potamida littoralis, doymamış yağ asidi, EPA, DHA.

Postlarval recruits of mussels Mytilus galloprovincialis were sampled in February 2003 at 7 localities along the Galicia coast (NW Spain) exhibiting different levels of impact from the 'Prestige' oil spill. These localities are important grounds for seed collection used in raft culture. The concentrations of polycyclic aromatic hydrocarbons (PAHs) as well as different biochemical and ecophysiological variables were determined in mussel tissues, as indicators of the toxic impact of the spilled oil. The following parameters were measured: size frequency distributions and size-weight relationships, survival in air, biochemical composition (proteins, carbohydrates, glycogen and lipids), lipid classes (phospholipids, sterol esters and waxes, triacylglycerols, free fatty acids and sterols), and fatty acid composition. The study determined sub-lethal effects in wild mussel seed populations sampled 3 mo after the oil spill. These effects are shown in the form of survival indices and alterations of lipid metabolism, especially in trygliceride and sterol fractions, as well as in saturated/monounsaturated fatty acid ratios. Monitoring these effects in wild mussel recruits is important for analysing growth, production and biochemical reserve cycle throughout the raft cultivation period and evaluating the capacity of the individuals to repair alterations detected in the juvenile stage.

“…They are related to the life cycle and external factors, such as temperature, salinity, and nutrition [15][16][17]. The geographical origin of the organisms is an additional factor that affects the lipid content and fatty acid composition of sea organisms [18]. To the best of our knowledge, in uence of season on the lipid and fatty acid compositions of A. amurensis have not been investigated to date.…”

The total lipid content, lipid classes and fatty acid composition in the internal organs of star sh (Asterias amurensis) were analyzed to determine the effects of seasons (winter and spring). The non-polar and polar lipid fractions obtained from star sh internal organs were analyzed through two seasons using thin layer chromatography (TLC) and gas liquid chromatography. Total lipid content of internal organs was 10.18% in spring and 8.21% in winter as wet weight basis. The predominant lipid class in spring was triglyceride whereas free fatty acids were the main lipid class in winter. The most abundant fatty acid of non-polar lipid fraction was eicosamonoenoic acid (C20:1) in spring having the highest proportion (29.2% of total fatty acid) as compared to the winter. Eicosapentaenoic acid (EPA) was also found signi cantly (P < 0.05) higher in spring compared to winter in the non-polar lipid fraction. On the other hand, comparatively lower amount of EPA was observed in spring than winter in the polar lipid fraction. Proportions of other fatty acids in non-polar and polar lipid fractions were also varied seasonally. This result might be useful for commercial production of lipid from internal organ of star sh with a view to potential use in food, pharmaceutical, cosmetics and other non-food industries.
