Large numbers of taste buds are distributed over the body surface of the channel catfish Zctalurus punctatus, with the barbels having an especially high density. L-Alanine, as well as certain other amino acids, are taste stimuli in this animal. Epithelial tissue obtained by gentle scraping of the barbel surface was fractionated by differential centrifugation. A sedimentable fraction (P2) was pr...

Infection of the barbel Barbus barbus (L. 1758) with endohelminths was observed in fish collected from eight localities in the Serbian part of the Danube River between September 2004 2009. Temporal variations in the number of parasites per fish sample were noted. A total of 194 fish specimens of different age, mostly males, were examined. The most prevalent parasitic species was the acanthoceph...

This study was carried out to determine population structure, growth and reproduction properties of barbel. A total of 198 individuals were sampled. Ages of samples were found between I and VI years, fork lengths between 4.3 and 16.6 cm and total weights between 1.2 and 65.8 g. Length-weight relationship was calculated as W=0.0146×L2.934. Munro’s phi prime index was estimated as 1.95, L∞ ...

One new species is added to the genus Sinocyclocheilus, the largest cyprinid genus in China and the largest cavefish genus in the world. Sinocyclocheilus gracilicaudatus sp. nov. is similar to S. donglanensis but differs to other congeners in having normal eyes and scaled body, curved lateral line with 59-64 lateral-line scale rows, half-hard dorsal fin spine, 8 gill rakers and 8 predorsal vert...

This study was conducted to determine ichthyofauna of the Büyük Karaçay stream of the River Orontes drainage in Turkey (eastern Mediterranaen basin). As the result of examination of the 911 individuals collected between June 2012 and May 2013, eight fish species belonging to five families have been recorded. Of these, African catfish Clarias gariepinus (Burchell, 1822), yellow barbel Carasobarb...

Accurate data on the distribution and population status of threatened fish species are fundamental for effective conservation planning management. In this work, in order to reassess globally Evia barbel, Barbus euboicus, we undertook an environmental DNA (eDNA) survey coupled with conventional electrofishing, focusing major river basins Island proximity its known occurrence a single Evian basin...
