All‐male populations of channel catfish, Ictalurus punelatus, were produced by feeding a
diet containing trenbolone acetate to swim‐up fry for 60 d. This hormone was effective in …

Annual sex hormonal profiles, gonad development and age determination of 18 (13–14 kg
body weight) and three (145–226 kg body weight) Mekong giant catfish (MGC) …

Gynogenesis was induced in silver carp, Hypophthalmichthys molitrix, to test female
homogamety for sex determination and subsequently, to produce genetic females for …

Induction of sex reversal of XY fish has been restricted to the sex undifferentiated period. In
the present study, differentiated XY tilapia were treated with trilostane (TR), metopirone (MN) …

Diploid gynogenesis was induced experimentally in the silver barb (Puntius gonionotus) as
the first step in a programme aimed at monosex female production. Sperm was exposed to …

In teleost fish, sex can be determined by genetic factors, environmental factors, or both.
Unlike in gonochoristic fish, in which sex is fixed in adults, sex can change in adults of …

Channel catfish have an XX female‐XY male sex determination system. Although genetic
males of this species are readily feminized with exogenous steroid, the pattern of gonadal …

The common carp, a gonochoristic teleost fish with an XX/XY sex-determining system,
provides an excellent model for studying cyprinidae gonadal sex differentiation. The present …

Atlantic halibut (Hippoglossus hippoglossus L.) females grow larger and mature later than
males, making monosex (all-female) culture economically advantageous. The objective of …

The objective of this study was to contribute to our understanding of the role of sex steroids
in fish sex differentiation and male maturation. Sexually undifferentiated sea bass were …
