ABSTRACT
Embryos of the fish Oryzias latipes were irradiated with 1000 R of X-rays 1 day before hatching,and the post-irradiation change in the female germ-cell population was observed. Scarcely any reduction in the number of oogonia was observed, but their proliferation was inhibited. Repopulation occurred between 12 and 20 days after hatching. These responses were quite different from those of germ cells in the irradiated fry (Hamaguchi and Egami 1975). Embryos and/or fry were also exposed to 1000 R of X-rays 1 day before hatching and 0, 1, 2, and 3 days after hatching. A comparison of their responses suggested that the change in the radiation responses of oogonia is correlated with the initiation of meiosis.
