Any of you fish nerds know anything about hormonal control of vitellogenesis in the Poecilia?? If not first hand do you know any papers or articles?? I have to write a paper on this and all my research has been dead-end...I know the hypothalamic-Pituitary-Gonadal (HPG) Axis of marine finfish like the back of my hand, but there seems to be nothing out there on the live bearers, any help??
