Abstract Black porgy, Acanthopagrus schlegeli Bleeker, is a marine protandrous
hermaphrodite fish. A Dmrt1 cDNA was cloned and characterized and in order to study the …

Protandrous black porgy fish, Acanthopagrus schlegeli, have a striking life cycle, with a
mono-male sex differentiation at the juvenile stage and male-to-female sex change at 3 yr of …

1. Changes in the time course of blood hemoglobin, hematocrit, leucocrit, chloride,
osmolarity, lactate, glucose and cortisol concentrations were monitored in salt-acclimated …

Human activities increase the occurrence of aquatic hypoxia (low dissolved oxygen)
globally. In fishes, short term hypoxia impairs multiple stages of reproduction (eg, behavior …

Unlike gonochoristic fishes, sex is fixed after gonadal differentiation (primary sex
determination), and sex can be altered in adults (secondary sex determination) of …

The objectives of the present study were to investigate the effects of oral administration of
estradiol-17β (E2) on luteinizing hormone (LH) in plasma, aromatase activity in gonad, and …

Controlling the development of the sexes is critically important for the broodstock
management in aquaculture. Sex steroids are widely used for sex control of fish. However …
