AbstractGynogenesis is a common method to manipulate chromosomes of aquaculture animals with sex dimorphism. The adverse effects on gonad development can be identified through morphology and histology. The goal of this study was to examine the gonadal development of twenty-three meiogynogenetic olive flounder Paralichthys olivaceus samples of two-years age using histological and immunohistochemical methods. We found that ovaries of nine individuals developed normally, while those of fourteen fish exhibited some distinct malformation, including a pair of asymmetrically developed lobes (divided into only one lobe and one slowly developed lobe) and a pair of slowly developed lobes. The remaining two had unidentified gonads filled with connective tissue, indicating that gynogenesis induced by cold shock exerts adverse effect on this species. However, all meiogynogenetic ovaries developed to phase II, similar to the corresponding control. Furthermore, compared to the female references, the same level of P450arom positive responses was received in the aforementioned ovaries, and they were localized in the follicles and oocyte cytoplasms. The above-described results elucidated that meiogynogenetic P. olivaceus diploids are equipped with reproductive potential to undergo normal ovarian development and ovulation, suggesting they could be cultivated as broodstock to produce inbred lines for increase in flounder yields and enhancement of farmers' interests.
