| The development of a new sex determination test of Siberian sturgeon based on vitellogenin (VTG) detection in plasma led to identify this complex factor in plasma from male, female and immature fish of this species. The hypothesis of an estrogenic contamination from an environmental origin was confirmed by a test based on the feeding of fish on different diets. In control fish fed with a casein-based diet free of any estrogenic compound, VTG disappeared from the plasma within 15 weeks. With a fish meal-based diet as well as with a soy-based diet, the plasma VTG levels raised significantly. Later, an estrogenic effect of soy orally administrated was demonstrated in vivo in the rainbow trout although it is lower than that observed in sturgeon. Soya is known... |
