Abstract Precise identifying of a Barbus fish species and the hybrids is very important because these fishes are large freshwaters fishes of Iran and the stock of them are going to vanished. In 2000 the Barbus species of Iran was revised at CMN and from that time all document of these species were reviewed, this is a part of this studies. In 1842 Heckel described Lebeobarbus kotschyi and named it in respect to Theodor Kotschyi. During the time this name has changed to Barbus kotschyi. Barbus kotschyi (Heckle, 1843) was synonymized with Barbus grypus Heckle, 1843 by several authors. The samples was examined In my projects the morphological differences between these two related species is enough to separate them, but for conceding them as two identical species more recherché has to be done and more samples must be collected. In this paper the more outstanding features and differences between these two species are outlined. The difference between this species and Barbus grypus, to which it is deceptively similar, lies mainly in the relative head length, the mouth, and the fleshy lobe below the symphysis of the lower jaw. In querying among 2000 professional angler, they states that have caught this fish and named it as a night touring fish.

In this study, in addition to the LC50 and the maximum allowable concentration, effects of silver nanoparticles on several of immune and blood serum enzymes parameters of Barbus grypus were determined For this purpose, 240 shirbut, to investigate the effects of sub lethal toxicity were divided as follows-control treatment (G1), the concentration LC50 1% (0.012 mg/L AgNP) (G2), concentration LC50 2% (0.025 mg/L AgNP) (G3) and concentration LC50 4% (0.05 MG/L AgNP) (G4) and concentration LC50 8% (0.1 Mg/ L AgNP) (G5). Then on days zero, 7, 14 and 21 immune responses and serum enzymes (ALT, LDH, SGOP, SGPT) in Barbus grypus were measured. In the study, WBC counts increased significantly (P<0.05) in G2, G3, G4 and G5 treatments compared to control (G1). Serum anti-bacterial activity was enhanced in G3 in twenty first day and G4 and G5 in 14th and 21s days in compared to control. Serum lysozyme activity enhanced significantly (P<0.05) in (G4) in 14th and (G5) 14th and 21s in days compared to control. ALT and LDH Level decreased significantly in (G2), (G3), (G4) and (G5) treatments in 21s day compared to control. SGPT level decreased significantly in (G2), (G3), (G4) and (G5) in 21s day compared to control. SGOT level decreased significantly in (G3), (G4) and (G5) treatments in 21s day compared to control. According to the results of this study concentrations toxicity of nano silver increased immune responses and serum enzymes.
