Abstract
In this research, which was conducted with the aim of identifying and survey of oogenesis and spermatogenesis of the dominant bivalves of the Karun River seasonally, bivalves after catching were transferred to the histology laboratory. The samples were then biometrically identified using valid identification books and keys. Gonads were examined histologically after dissection and isolation and tissue passage. The results showed the presence of the invasive alien species Sinanodonta woodiana (a bivalve clam from the Unionidae family) that for the first time was isolated and identified from the muddy sediments of the Karun River only in spring. The results of the histological studies of the gonads showed that the individuals of this species were heterosexual. Ovary was asynchronous type because at any time all types of female sex cells (oogonia, pre vitellogenic oocytes, vitellogenic oocytes) were visible in the ovaries. Also, due to the presence of a large number of sperm in the lumen of the testicular follicles, intense spermatogenesis and the male gonad seemed developed and mature in this season.
