The reproductive biology of golden barb (Barbus luteus Heckel, 1843) in Maroon River, Iran

Golden barb (Barbus luteus) is one of the species in south and southwest of Iran which is greatly favorable to residents of the region. Unfavorable ecological conditions in habitat of this species and overfishing have led to reduction of the population of golden barb. Therefore, to restore the natural stock of this species, identifying its reproductive cycle associated with its habitat is of a ...

Reproductive biology of lotak, Cyprinion macrostomum Heckel, 1843 (Pisces: Cyprinidae), from the Tigris River drainage

Some reproduction aspects of the "doctor fish", Cyprinion macrostomum, were examined for the first time from the Tigris River drainage. A total of 316 specimens were caught from Gamasiab River in western Iran, at monthly intervals throughout the year from January to December 2013. Age, sex ratio, fecundity, oocytes diameter, gonado‑somatic (GSI), modified gonado‑somatic (MGSI) and Dobriyal (DI)...

Macroscopic and microscopic studies of annual ovarian maturation cycle of Shirbot Barbus grypus in Karoon river of Iran

The aim of this investigation was to study macroscopic and microscopic structures of ovaries in Barbus grypus of Karoon river and their changes during annual maturation cycle. For this purpose, 120 adult  B.grypus with a mean weight of 835.0 to 1012.0 g, were caught from Karoon river and transferred alive to the laboratory. After biometrical studies, the weights and morphological appearances of...
