Chiton lamyi species collected from the intertidal zone of Chabahar bay analyzed seasonally for its fatty acid compositions in foot. Thirteen fatty acids identified in both sections by gas chromatography/mass spectroscopy. Major unsaturated fatty acids were palmitoleic acid, oleic acid and 11-eicosenoic acid and PUFAs included linoleic acid, eicosapentaenoic acid and arachidonic acid. Effects of monthly temperature and nutrients (silicate, phosphate and nitrate) investigated to detect seasonal variations of fatty acids. Pearson analysis results showed correlation among palmitic and oleic acids with silicate and phosphate linoleic and arachidonic acids with nitrate in Chiton lamyi internal tissues, but no correlation observed in foot. Heptadecanoic and methyl- heptadecanoic acids contents and temperature correlated strongly in Chiton lamyi foot. |
