Scanning Electron Microscopy of the scale morphology in Cyprinid fish, Rutilus frisii kutum Kamenskii, 1901 (Actinopterygii: Cyprinidae)
The normal and lateral line cycloid scales of a cyprinid fish Rutilus frisii kutum Kamenskii, 1901 have been subjected to scanning electron microscopy technique to study their detailed structure. The scales have the general morphological characteristics of the cycloid scales. In the normal scale located below the dorsal fin, the focus lies on the anterior region with few mucous pores. There is ...

متن کاملLabeo rosae (Cypriniformes: Cyprinidae) in the Congo basin: a relict distribution or a historical introduction?
Labeo rosae, a species with a native range in Southern Africa, was discovered in the Congo basin by re-identification of two museum specimens previously identified as Labeo mesops. The occurrence of this species in the upper Congo implies a range extension of the species of more than 1000 km. Although the species' distribution is mirrored by that of some other Cypriniformes, its occurrence in t...
متن کاملpreliminary study of in vivo formed dental plaque using confocal microscopy and scanning electron microscopy
objective: confocal laser scanning microscopy (clsm) is relatively a new light microscopical imaging technique with a wide range of applications in biological sciences. primary value of clsm for the biologist is its ability to provide optical sections from three-dimensional specimen. the present study was designed to assess the thickness content of in vivo accumulated dental plaque using clsm a...
متن کاملultrastructural changes in the gills of a cyprinid fish, labeo rohita (hamilton, 1822) through scanning electron microscopy after exposure to lead nitrate (teleostei: cyprinidae)
labeo rohita fingerlings were reared in freshwater and exposed to different concentrations of lead nitrate. after the exposure, one fish was sacrificed from each dose and the gill arches were removed. the ultrastructural changes on the gills of this cyprinid fish were investigated through scanning electron microscope (sem). lead treated gill tissues showed certain marked changes such as uplifti...
