We tested different hypotheses related to the origin and evolution of the endemic Iberian fishes Chondrostoma arcasii and Chondrostoma macrolepidotus from northern and central regions of the Iberian Peninsula. We evaluated the monophyly of the populations within each species and sought to determine if diversification of the populations coincided in time with the formation of the Iberian drainag...

Previous molecular phylogenetic studies of the genus Chondrostoma (Cyprinidae: Leuciscinae) were unable to resolve the relationship among its major species groups. In this paper we present a phylogeny for this genus, based on five mitochondrial genes and the nuclear gene beta-actin, comprising a total of 4068 bp. Bayesian inference using all gene fragments yielded a fully resolved phylogeny, co...

the length-weight relationships for three fish species from beheshtabad river, karun river drainage (western chaharmahal and bakhtiari provinces, iran) were investigated. the values of the slope parameter ( b ) in the length-weight relationship equations were determined as 2.79 for capoeta damascina , 3.10 for chondrostoma regium and 3.09 for oncorhynchus mykiss , all of which were significantl...

The Chondrostoma genus is widespread in Europe, with numerous endemic species in northern Mediterranean rivers. We reconstructed the phylogenetic relationships of this genus, using the whole cytochrome b sequence and compared the two freshwater fish dispersion hypotheses: (1) dispersion around the Mediterranean Sea during the Lago Mare phase of the Messinian salinity crisis (Bianco's hypothesis...

occurrence of lernaea parasite in a narrow distributed endemic fish, chondrostoma orientale (oriental nase) restricted to the kor river basin, southwestern iran is reported. based on the obtained results, all three collected specimens (tl= 174-192mm, sl= 148-169mm) were infested with lernaea parasites which were attached to the base of dorsal, pectoral, caudal and pelvic fins and also body musc...

İron Sazlığı Bitlis İli’nde yer alan Türkiye’nin önemli sulak alanlarından biridir. Alanda yaşayan karaburun balığı (Chondrostoma regium Heckel, 1843) bölge halkı tarafından yoğun bir şekilde tüketilmektedir. Bu çalışmada, balıkçılar Kasım (2019) tarihinde yakalanan balıkların besin kompozisyonunun belirlenerek yöre için besinsel değerinin incelenmesini amaçlanmıştır. kapsamda; balıkçıdan temin...
