the aim of this study was to provide necessary information on the age, growth and sex ratio of one of commercially important cyprinid species, alburnus chalcoides in the southern caspian sea (north iran) from 2010 through 2011. 53 specimens of both sexes (males and females) were collected monthly. the samples were transported tothe laboratory for further biological measurements and otolith extr...

Piscivory in cyprinids (Cyprinidae) is extremely rare. Specifically, common bream (Abramis brama) and common carp (Cyprinus carpio) are zooplanktivorous fish in deep lentic waters. Nevertheless, we observed predation by these two cyprinids under natural conditions in the Vír Reservoir, Czech Republic. We conducted diet analysis for cyprinids caught by trawling and gillnets and the large amount ...

The gills of fish have a great external contact surface and are particularly sensitive to chemical and physical changes in the aquatic environment. The aim of this study was to examine the histopathologic alterations in the gills of Astyanax fasciatus and Cyanocharax alburnus and to determine if there is a correlation between the severity of the alterations and environmental degradation and if ...

A total of 398 specimens of 14 cyprinid species were examined for the presence of renal sphaerospores and Sphaerospora blood stages (C blood protozoa). Sphaerospora infection of the kidney was demonstrated in 122 fish of 12 species, and blood stages were found in the blood of 30 fish of 6 species. Blood stages only occurred in f.ish infected by renal sphaerospores and were primarily demonstrabl...

Since 2007 about 200 to 300 fish per year--generally roach (Rutilus rutilus) also a few bleak (Alburnus alburnus) and eels (Anguilla anguilla)--have been collected from a number of English river sites and stored at -80°C to build up a Fish Tissue Archive as a resource for the monitoring of pollutants. Some of the fish from the Fish Tissue Archive from the years 2007-2011 were analyzed for subst...

This study was carried out to determine the fish fauna of Kuzgun Dam Lake dranaige. Eight (Barbus lacerta, Capoeta damascina, Alburnus sellal, Alburnoides velioglui, Squalius semae, Oxynoemacheilus araxensis, O. bergianus and Salmo euphrataeus) species belonging 4 families (Cyprinidae, Leuciscidae, Nemachelidae Salmonidae) were determined.

Fifteen new polymorphic microsatellite markers were developed for Culter alburnus. In 32 individuals representing a wild population of the Danjiangkou Reservoir, Hubei, China, the number of alleles at these loci varied between 2 and 10, with an average of 5.5. The average observed and expected heterozygosities were 0.664 and 0.681, respectively. The polymorphism information content of 11 loci w...
