"Ten years have gone by since one of the weirdest discoveries in the Chesapeake Bay region, on the south branch of the Potomac River — male smallmouth bass with lady parts, eggs in places where they absolutely should not be."
"Over that decade, wildlife biologists have probed the bay’s tributaries, slicing open fish for more necropsies than anyone can count. And one thing is clear: They still aren’t sure why between 50 and 100 percent of bass in various locations are gender-bending, switching from male to something called intersex.
Biologists say studies are falling short because of a lack of data on the type and quantity of pesticides that run into the bay from farms. This complaint, along with other factors, prompted Democrats in the Maryland House and Senate to sponsor two bills in the current legislative session that would for the first time require growers to record their use of insecticides and herbicides and submit it to the state."
