The purpose of this study is to estimate some population parameters such as length-length and length-weight relationships condition factor Squalius cephalus individuals living in Tabakane Stream (Ordu-Turkey). A total 326 S. were sampled from Stream, located Ünye district the Ordu province, by using an electroshocker. It was determined that mean total, fork standard lengths fish samples 7.58±0....

Squalius alburnoides is a widely distributed intergeneric hybrid complex with fish of both sexes, varying ploidy levels and proportions of the parental genomes. Its dispersal routes were here delineated and framed by the reconstruction of the phylogeny and phylogeography of other Squalius with which it hybridizes, based on the available data on the paleohydrographical history of the Iberian Pen...

Aim In this study, fish species living in the Elekçi Stream, which poured from borders of Fatsa District Ordu Province to Black Sea, were determine as taxonomical. Material and Methods samples taken Bolaman Rivers using an electroshock device six pre-determined stations between January 2017 October 2018. Specimens brought laboratory. The then stored formaldehyde solution (4%) for further examin...

This study assessed the distribution of heavy metals in gills, kidney, and liver, correlated with severity histopathological changes, three fish species different feeding habitats (Barbus barbus, Squalius cephalus, Chondrostoma nasus) from Cri?ul Negru river, Romania. The levels copper (Cu), chromium (Cr), cadmium (Cd), lead (Pb), zinc (Zn) tissues were measured by atomic absorption spectrophot...

Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%. Unaffected were only Barbus barbus (L.), Chondrostoma nasus Cyprinu...

The accumulation of iron, zinc, copper and cobalt in the muscles of three freshwater fish (Cyprinus carpio, Squalius cephalus and Capoeta umbla) from Keban Dam Lake (Turkey) were investigated between September 2009 and April 2010. The concentration of heavy metals were found as Zn>Fe>Cu>Cd respectively. A positive relationship was found between heavy metal levels and fish size. The levels of al...

Some Cyprinid fish species: Cyprinion macrostomum (Heckel, 1843), Capoeta umbla Chondrostoma regium and Squalius cephalus (Linnaeus, 1758) living naturally in the Murat River, were investigated for Protozoan Crustacean parasite fauna their distribution. Fish samples collected from different stations between July 2017 - June 2019, examined Bingöl University Zoology Research Laboratory, data expl...
