Abstract
In the present study, we investigated the histology and oocyte size va riations in ovaries from barbel reared in captivity. We demonstrated t hat the size distribution of intraovarian oocytes is quadrimodal (incl uding primary oocytes, oocytes with vacuoles, vitellogenetic oocytes a nd ova), Indicating that oocyte development can be found in the ovarie s (some oocytes are in late vitellogenesis). The ovarian structure is discussed in realation to the repeated spawnings observed in captivity .
