ABSTRACT
The mating systems of the teleosts range from promiscuity to polygamy and to monogamy. Available information on this theme has been reviewed from time to time; however, they are limited to monogamy (Barlow, 1984, 1986, 1988) or to one group of fi shes (e.g. coral-inhabiting hermaphrodites, Moyer et al., 1983; Colin and Bell, 1991; cichlids, Kuwamura, 1986). A comprehensive account for the group teleosts is still wanting.
