The determination of sex is an important hallmark in the life cycle of organisms, in which the
fate of gonads and then the individual sex are defined. In gonochoristic teleost fish, this …

The exposure of adult fish to warm or high temperatures is known to impair reproduction, yet
the long-term reproductive impacts for treatments at early life are not well clarified. This study …

The growth rate of allotetraploid common carp (Cyprinus carpio) is sex dimorphic. Thus,

side adaptative responses to environmental changes and potential life threats, and 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 …

Sex-determining genes have been successively isolated in several teleosts. In Odontesthes
