Japanese flounder (Paralichthys olivaceus) is a teleost fish which has a XX (female)/XY (male) sex determination mechanism. Genetic females can be experimentally sex-reversed to phenotypic males when the larvae are reared at high water temperature or treated with androgens, providing an excellent model to study mechanisms of gonadal sex differentiation in teleost fishes.
In the present paper, I review recent findings on gonadal sex differentiation in Japanese flounder, and then discuss mainly about roles of sex steroid hormones on the sex differentiation.
