Sturgeon's General Warning

Sounds as though salmon aren't the only Columbia River fish in trouble:

A team of researchers that examined 174 sturgeon caught by commercial and tribal fishermen found male and immature females tricked by chemicals into thinking they are full of estrogen, a female hormone with feminizing effects. Male fish tainted with a cocktail of compounds including mercury and a byproduct of the banned pesticide DDT showed depressed testosterone levels, which could keep them from maturing enough to spawn.

A few sturgeon even had bizarre combinations of male and female sexual organs. [Emphasis added.]

All I have to say to that is:  eewww.  If that doesn't serve as a wakeup call about gender-bending pollutants, I'm not sure what will.
