The present review focuses on the roles of estrogens and aromatase (Cyp19a1a), the
enzyme needed for their synthesis, in fish gonadal sex differentiation. Based on the recent …

Hormones are used in fish farming to increase fish production when one sex of a species
has the capacity to grow bigger and faster than the other sex. The technique to increase fish …

Yellow catfish has become one of the most important freshwater aquaculture species in
China. The mono-sex male yellow catfish has important application value in aquaculture …

Sex controls have been performed in some farmed fish species because of significant
growth differences between females and males. In yellow catfish (Pelteobagrus fulvidraco) …

The sex-determining genes are found to be variable among different fish species. Yellow
catfish (Pelteobagrus fulvidraco) is an important aquaculture fish species in China with …

The involvement of sex steroids in sex determination and differentiation is relatively
conserved among non-mammalian vertebrates, especially in fish. Thanks to the advances in …

We systematically investigated the feminization of bluegill Lepomis macrochirus by oral
administration of various doses of estradiol-17β (E2) and evaluated their effects on the …

Gonadal sex differentiation in teleost fish shows greater plasticity as compared to other
vertebrates, as it can be influenced by a variety of factors such as exogenous sex steroids …

Monosex populations are in demand in many fish species with sexual dimorphism, eg, better
growth performance, higher gonad value, superior ornamental value. From the point of view …

Many environmental stressors, including stress temperature, high density, hypoxia, low food
availability, high social pressure, and bright background colour, have been found to cause …
