Ovarian growth and plasma sex steroid and vitellogenin profiles during vitellogenesis in Tasmanian female Atlantic salmon ( Salmo salar)
In order to provide detailed information on the reproductive development of female Atlantic salmon (Salmo salar) in Tasmania, Australia, fish were sampled from sea cages during the main period of vitellogenesis over the austral summer and autumn (October-March). Plasma levels of the gonadal steroids...
