It was demonstrated that males of rose bitterling Rhodeus ocellatus ocellatus were able to discriminate post-ovulatory females from pre-ovulatory ones on the basis of a chemical cue. And also males of slender biterling Acheilognathus lanceolatus were able to discriminate between post-ovulatory females and pre-ovulatory ones on the basis of a chemical cue. Some important aspects derived from the experiments are listed as follows; 1. Post-ovulatory females of each species released a female sex pheromone respectively, which males detect by olfaction. 2. The pheromone of each species was present in the genital cavity fluid and in the ovaries of post-ovulatory females. 3. Males of each species discriminated post-ovulatory females of their own kind from those of other species by olfaction. And difference of female sex pheromone was observed between the two bitterlings.
