In fishes reproduction is normally sexual by fertilization of male and female
reproductive elements borne by individuals of the two separate sexes. However,
certain reproductive specializations, viz. gynogenesis, parthenogenesis and hermaphroditism
are at times met with. Gynogenesis is observed in Mollienesia formosa
(Hubbs and Hubbs, 1932, 1946) which exclusively occurs as females, wherein during
reproduction the sperms of a related species only stimulate the eggs but do not contribute
to any genetic material and the resulting offspring are all females. Gynogenesis
has also been observed in a cyprinid fish Carassius auratus gibelio (Lieder,
1955). Parthenogenesis or development of eggs without fertilization is very rare.
