Origins and biogeography of the chub, genus Squalius (formerly within the genus Leuciscus), in the Iberian Peninsula were inferred from comparison between patterns of geographic distribution and phylogenetic relationships among populations belonging to 14 European Squalius species. The phylogeny recovered was based on the complete sequence of the mitochondrial cytochrome b gene. Squalius specie...

pomphorhynchus laevis is a common fish parasite in europe which   has been reported from acipenser stellatus, barbus capito, barbus lacerta, barbus mursa and onchorhynchus mykiss in iran. in a survey on the aquaculture potential of gamasiab river in hamedan province, endemic fish parasites were investigated in summer and autumn 2008. after recording biometric characteristics, common necropsy an...

the aim of this study was to determine and compare the concentration of copper (cu) in liver and muscle of two fish species squalius cephalus and capoeta capoeta gracilis. the fish were caught in four sampling sites along tajan river, mazandaran province, northern iran. the concentration of cu was determined using flame atomic absorption spectrometry. there were significant differences (p

Fatty acid composition of fish is one of the key factors for the evaluation of fish nutritional value and it could be different based on fish species, habitat, nutrition and etc. The aim of the present study was to evaluate the fatty acid composition of five commercially important freshwater fish from the fish market. Studied fish were as follows: Barbell, Luciobarbus pectoralis (Heckel, 1843),...

The chub is an opportunistic, rheophilic cyprinid species and popular gamefish distributed throughout almost all of Europe, South Caucasus and part of Anatolia. It is most abundant in small rivers and large streams. The process of anatomical and cytological differentiation was analyzed in chub gonads. Material used in the study was derived from artificial spawning of adult individuals caught in...

The chub is a freshwater fish of the family Cyprinidae, which is widely distributed throughout Europe. Prior to 2001 there were no reports of chub being present in Ireland. In 2001 and again in 2004 it was reported that an angler had caught chub in a section of the River Inny. On neither occasion were live specimens retained for authentication. In 2005 a number of live, angler-caught chub from ...

In this study, seasonal variations in the fatty acid profiles of the liver and muscle of Squalius cephalus from Tödürge Lake were determined by Gas Chromatography (GC). C22:6 n-3, C20:5 n-3, C20:4 n-6, C18:1 n-9, C18:1 n-7, C16:1 n-7, C18:0 and C16:0 were the principal fatty acids showing the highest levels in the muscle and liver of Squalius cephalus in all seasons. Although C22:6 n-3, which i...
