Abstract
Production of all-female progeny in Nigorobuna, Carassius carassius grandoculis was attempted with sex-reversed males. Gynogenetic diploids of nigorobuna were produced by the cold-shock treatment of the eggs for preventing the extrusion of the second polar body. Administration of 17-methyltestosterone for the sex reversal from female to male was performed by dissolution in the rearing water at 1.0μg/l (8h per day) for 60 days from 25 days after hatching. Proportion of males in the hormone-treated fish increased significantly. Since these males produced almost all female offspring, they were regarded as sex-reversed males. Sex-reversed males used at a commercial level allowed the production of all-female progeny. From these results, the sex determining system of Nigorobuna was presumed to be female homogamety.
