Also note a similar finding, also for medaka, by a different group:

fish (and chondrichthyes?). It has already been noted that fishes display
many different types of sex determination systems, from hermaphroditism to
gonochorism, and from environmental sex determination to genetic sex
determination including male and female heterogamety, polyfactorial systems
and autosomal influences. Seems to me as if our imagination is limiting the
number of reproduction systems. For  those interested but not familiar with
this topic, here a link to a very nice site;
