    A Comparative Study on Proximate, Mineral and Fatty Acid Compositons of Deep Seawater Rose Shrimp (Parapenaeus longirostris, Lucas 1846) and golden Shrimp (Plesionika martia, A. Milne-Edwards, 1883)
    (Medwell Online, 2009) Oksuz, Abdullah; Ozyilmaz, Ayse; Aktas, Mevlut; Gercek, Gozde; Motte, Jelena
    Proximate, Fatty Acids (FA) and element compositions of two shrimp species, deep seawater rose-shrimp (Parapenaeus longirostris) and golden shrimp (Plesionika martia), were determined. Amount of lipid in P. longirostris and P. martia was found as 1.1 and 2.61%. Proportion of lipid in both shrimps was lower than that of marine fish. Surprisingly, FA profile of these 2 shrimp species can be comparable with that of marine fish. The amounts of PUFA's in both shrimp species were found higher than those of SFA and MUFA. Level of DHA in P. longirostris was significantly (p<0.05) higher than that of P. martia. In addition, major macro elements found in both of the shrimp species were Ca, K, Na, P and Mg. Zinc and iron were the major micro elements followed by Cu and Mn. Heavy metals such as, Cd and Cr, were in below the safe limits.

    Fatty Acid Composition and Mineral Content of Upeneus moluccensis and Mullus surmeletus
    (Central Fisheries Research Inst, 2011) Oksuz, Abdullah; Ozyilmaz, Ayse; Kuver, Senol
    Lipid, moisture, fatty acid, and mineral contents of gold band goatfish (Upeneus moluccensis) (Blecker, 1855) and striped red mullet (Mullus surmuletus) (Linnaeus, 1758) were investigated. The lipid and moisture contents in the two species were found to be significantly different from each other (P<0.05). Lipids of striped red mullet include significantly (P<0.05) higher levels of C14:0, C15:0, C16:1, C17:1, C18:1n9, C18:2n6, C20:3n6, DHA (Docosahexaenoic Acid, C22:6n3) and EPA (Eicasapentaenoic Acid, C20:5n3) fatty acids than those of gold band goatfish. Proportions (%) of SFA (Saturated Fatty Acid), MUFA (Monounsaturated Fatty Acid), and PUFA (Polyunsaturated Fatty Acid), DHA/EPA, and n3/n6 were found to be 39.30, 26.81, 32.18, 3.26, and 5.35 for gold band goatfish and 36.72, 41.83, 18.92, 0.89, and 3.31 for striped red mullet, respectively. K and P were found to be predominant among the 11 measured minerals in the two species. Only the K, Ca, and Na content of the two fish species were found to be significantly different (P<0.05).

    Proximate Composition, Fatty Acid Profile and Mineral Content of Wild Brown Trout (Salmo trutta sp.) From Munzur River in Tunceli, Turkey
    (Asian Journal Of Chemistry, 2011) Kayim, Murathan; Oksuz, Abdullah; Ozyilmaz, Ayse; Kocabas, Mehmet; Can, Erkan; Kizak, Volkan; Ates, Mehmet
    In present study, the proximate composition, fatty acid profile and mineral content of wild brown trout living in Munzur river (Tunceli/Turkey) were investigated. The average level of protein, lipid, moisture and ash content of muscle of the wild brown trout was calculated to be 17.48, 2.3, 77.8 and 1.5 %, respectively. Thirty fatty acids were identified in this study. Identification of the fatty acid was carried out with gas chromatography-mass spectrometry (GC-MS). The total polyunsaturated fatty acids (PUPA) were found the highest fatty acid followed by that of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). Docosahexaenoic acid (DHA, C22:6n3) and eicosapentaenoic acid (EPA, C20:5n3), linolenic acid (LNA, C18:3n3) and linoleic acid (LA, C18:2n6) were found to be predominant fatty acids in PUFAs with the percentages of 11.25, 6.82, 6.30 and 4.88, respectively. The ratio of n3/n6 and DHA /EPA was calculated to be 4.55 and 1.65, respectively. Twelve elements were determined in this study. Determination of elements was performed with ICP-AES. P and K were the predominant element among the minerals analyzed and calculated to be 1305.56-2967.06 and 1908.68-1220.10 mg kg(-1) in muscle-skin of the wild brown trout, respectively.
