Recently established models for genomic studies (the Japanese and freshwater pufferfish, Fugu rubripes and Tetraodon nigroviridis, respectively) and for develop- mental biology (the zebrafish, Danio rerio) are now the focus of interest of many biologists, although ‘old’ models are still useful for the study of tumorigenesis (platyfish, Xiphophorus) and evolution, radiation and speciation (African cichlids), as well as for the evolu- tion of sex determination and developmental genetics (the medaka, Oryzias latipes). Although the zebrafish and its features as an experimental system are well known among scientists within and outside the field, knowledge of the medaka has so far been restricted (with a few exceptions) to its home range, Japan, and some other countries in the Far East. In Japan, the breeding of medaka colour variants for ornamental purposes is a tradition that goes back several centuries. In the early twentieth century, the medaka was recruited as a model species for biological and genetic research. In fact, it was the study of the inheri- tance of body colour in the medaka by Toyama in 1916 that proved that Mendelian laws also apply to fish (Toyama, 1916). Another milestone achievement was the discovery of Y-chromosome-linked inheritance by Aida in 1921 (Aida, 1921). Within the past s
