Let me explain: When we began working on our story about Whole Foods' new farmed seafood standards, one bullet point caught our eye: No Methyl testosterone for sex reversal.

Any fish that were on the path to a womanly fishhood change course to become strapping male tilapia instead, turning the pond into one big fishy frat party.
