Öğe Age and growth of the Randall's threadfin bream Nemipterus randalli (Russell, 1986), a recent Lessepsian migrant in Iskenderun Bay, northeastern Mediterranean(Wiley, 2010) Erguden, D.; Turan, C.; Gurlek, M.; Yaglioglu, D.; Gungor, M.P>Randall's threadfin bream, Nemipterus randalli, first recorded in Iskenderun Bay in Turkey in 2008, seems to have increased in the region. The species, widespread in the western Indian Ocean and with a rapid expansion, appears to have migrated to the bay via the Red Sea. Although its presence in the region has been published, there has been little or no information as to age and growth parameters of this Lessepsian migrant in its new habitat. The present study aims to determine the basic age and growth parameters of the species colonized in the region. A total of 379 collected individuals were studied from November 2007 to October 2008. Total specimen lengths ranged from 4.80 to 21.50 cm, and weights from 1.10 to 138.36 g. Maximum age was 3 years for both sexes. The length-weight relationship was described as W = 0.0011 x L3.061 (r2 = 0.982). The von Bertalanffy growth parameters were: L-infinity = 34.96 cm; K = 0.214 year-1; t(0) = -1.244 year for the entire population. These data were compared with results from studies made in other geographic areas.Öğe First record of the blue-barred parrotfish, Scarus ghobban Forsskal, 1775 from Turkish coastal waters(Hindawi Ltd, 2014) Turan, C.; Erguden, D.; Gurlek, M.; Yaglioglu, D.; Uygur, N.[Abstract Not Available]Öğe First record of the broad-banded cardinal fish Apogon fasciatus (White, 1790) from Turkey(Natl Centre Marine Research, 2010) Turan, C.; Yaglioglu, D.; Erguden, D.; Gurlek, M.; Sonmez, B.Two specimens of the alien cardinal fish Apogon fasciatus (White, 1790) are recorded for the first time in Turkey and second time in the Mediterranean Sea. This is the fourth Indo-Pacific apogonid species documented in the Mediterranean Sea, and the introduction of this species to the eastern Mediterranean is due to migration from the Red Sea via the Suez Canal.Öğe First record of the Spiny blaasop Tylerius spinosissimus (Regan, 1908) (Tetraodontidae) from the Turkish coasts(Natl Centre Marine Research, 2011) Turan, C.; Yaglioglu, D.The non-indigenous tetraodontid of Indo-Pacific origin Tylerius spinosissimus is recorded for the first time in Turkish waters and for the third time in the Mediterranean Sea. This record increases to 53 the number of Indo-Pacific alien fish species present along the coasts of Turkey.Öğe Genetic differentiation of Mediterranean horse mackerel (Trachurus mediterraneus) populations as revealed by mtDNA PCR-RFLP analysis(Wiley, 2009) Turan, C.; Gurlek, M.; Yaglioglu, D.; Ozturk, B.The genetic population structure of Mediterranean horse mackerel, Trachurus mediterraneus, from seven locations throughout the Black, Marmara, Aegean and eastern Mediterranean seas was investigated using restriction fragment length polymorphism (RFLP) analysis of the mtDNA 16S rDNA region. An approximately 2000-bp segment was screened in 280 individuals using six restriction enzymes, resulting in 10 composite haplotypes. The most common haplotype was present in 56.42% individuals; the next most frequent haplotype was present in 22.85% individuals. Average haplotype diversity within samples was moderate (0.38), and nucleotide diversity was low (0.00435). Mean nucleotide divergence for the seven sampling sites was 0.0028. Nucleotide divergence among samples was moderate, with the highest value detected between the Aegean Sea (Izmir) and the eastern Black Sea (Trabzon) populations (0.007055), and the lowest (-0.000043) between the Marmara Sea (Adalar) and the western Black Sea (Sile) populations. In Monte Carlo pairwise comparisons of haplotype frequencies, the Sinop from the middle Black Sea, Trabzon from the eastern Black Sea, and Iskenderun Bay from the north-eastern Mediterranean Sea exhibited highly significant (P < 0.001) geographical differentiation from each other and from all other populations. Mantel's test indicated that the nucleotide divergence among populations of T. mediterraneus was not significantly associated with their geographical isolation (r = -0.2963; P > 0.05). Consequently, the mtDNA 16S rDNA region provided evidence for the existence of three distinct T. mediterraneus populations (Sinop, Trabzon and Iskenderun Bay) in the Black and north-eastern Mediterranean seas.Öğe Occurrence of Schedophilus ovalis (Cuvier, 1833) (Osteichthyes: Centrolophidae) in the North-Eastern Mediterranean, Turkey(Wiley, 2013) Erguden, D.; Yaglioglu, D.; Turan, C.[Abstract Not Available]Öğe On the occurrence of the giant devil ray Mobula mobular (Bonnaterre, 1788) from the Mediterranean coast of Turkey - a by-catch documentation(Wiley-Blackwell, 2013) Yaglioglu, D.; Turan, C.; Gurlek, M.[Abstract Not Available]
