Poison pill could eradicate Asian carp, but at what cost?

 


Biologist Jon Amberg has spent the past two years obsessed with fish guts, laboring over a singular challenge: Develop a poison pill that will kill Asian carp and leave other fish unscathed.
Voracious and freakishly resilient, the fish has left a trail of destruction on its decades-long migration up the Mississippi River and into Illinois, seemingly undeterred by the ordinary ammo of invasive-species warfare.
Now, designer drugs and engineered poisons, often called "bio-bullets," have become increasingly popular among scientists trying to create sniper-shot solutions to unyielding problems, from malignant pests in rivers and fields to tumors in human bodies.
