some 190 specimens of sefidrud loach, oxynoemacheilus bergianus , were collected from aras river (northwestern iran) and age, size, and some biological characteristics of the samples were investigated from march to july 2013. the maximum age was 3 + years. the specimens ranged in size from 42 to 64mm for males and 45 to 61mm for females in total length, weighing from 0.62 to 2.03g for males and...

The Picobirnaviruses (PBVs) have been detected in several species of animals from different countries worldwide, including in South America. The host range of these viruses has increased in recent years; thus, in order to contribute to the knowledge in this topic we analyzed samples from captivity animals from Uruguay. We found the presence of PBVs in four species of animals, Panthera leo, Pant...

The chromosomal banding properties of Oxynoemacheilus simavicus (Balık & Bănărescu, 1978) were revealed out by C-banding and silver staining. Constitutive heterochromatin regions determined on the pericentromeres most chromosomes C-banding. Otherwise, nucleolus organizer (NORs) observed short (p) arms one middle-sized submetacentric (sm) chromosome pair Also, Ag-NOR size number polymorphism...

length-weight relationship and condition factor were investigated in seven fish species, including barbus cyri , capoeta gracilis , alburnoides eichwaldi , acanthalbarnus microlepis , ponticola cyrius , cobitis keyvani and oxynemacheilus bergianus from totkabon river. a total of 570 specimens ranging from 25.90 to 146.97 mm in total length and 0.1 to 260.3 g in total weight were collected. base...

this study was carried out to investigate the genetic diversity and population structure of 90 specimens of oxynoemacheilus argyrogramma collected from sepidbarg, gamasiab and ghaleji rivers, in the west of iran. analyses using three microsatellite loci indicated that the average number of alleles in the population was 12, which was well above the reported values for freshwater fishes. the expe...
