Résumé

Plasma levels of estradiol (E2) testosterone (T), 11-ketotestosterone, 17,20bP and vitellogenin (VTG ) are reported for the first time in mature male and female sturgeon, Acipenser sturio. T (40 ng/ml) correlates each year with spermiation. High E2 (33 ng/ml) correlates with VTG (90 mg/ml) and maturation.
