    An Electrophoretic Taxonomic Study on Serum Proteins of Acanthobrama marmid, Leuciscus cephalus, and Chondrostoma regium
    (EurAsian Journal of BioSciences, 2007) Yılmaz, Muhittin; Yılmaz, H. Ramazan; Alas, Ali
    In this study, native polyacrylamide gel electrophoresis (Native-PAGE) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) were applied to the serum proteins of Leuciscus cephalus, Acanthobrama marmid and Chondrostoma regium (Cyprinidae) fish taken from) the Karakaya Dam (Malatya, Turkey). The electrophoregrams showed that there were similarities and differences in the molecular weight (MW) of the serum proteins among the three species. In the Native-PAGE, the total number of serum protein bands of L. cephalus, A. marmid and C. regium were 5, 8, 7, respectively. In the SDS-PAGE, 13 protein bands were obtained in L. cephalus, 11 in A. marmid and 11 in C. regium. In the electrophoregrams obtained from native-PAGE, the MW of the protein bands were found to be different in the fish species except the 80.3 kD protein band which was detected in the three fish species. In the SDS-PAGE, the protein band of 21.7 kD was observed in the three fish species. Protein bands of 63.4, 52.3 and 49.5 kD were present only in L. cephalus and C. regium. On the other hand, it was seen that other protein bands had similar molecular weights.

    Biometry of the Fishes Barbus plebejus and Barbus capito from Çoruh Basin, Turkey
    (International Journal of Tropical Biology and Conservation / Revista de Biologia Tropical, 2009) Solak, Kemal; Alas, Ali; Yılmaz, Muhittin; Öktener, Ahmet
    Metric and meristic characters are important to identify fish species and their habitat peculiarities. There are many species that belong to the fish genus Barbus, which is found in tropical and extratropical regions, but there are few studies covering the Coruh basin. Two subspecies of Barbus were found in the Coruh River system of Eastern Anatolia, Turkey: Barbus plebejus escherichi and Barbus capito capito. We collected specimens in seven localities for measurement. The number of vertebra were determined radiographically. Some specimens of B. capito capito have a sharper snout in the segments of Coruh where the water flows faster, suggesting a modification related to current. The biometric measurements vary geographically and could be related to abiotic and biotic factors in the habitat.
