Same white flesh. Same protein. Often the same river. So why does tilapia feel normal on your plate while carp feels like garbage? The answer has almost nothing to do with taste — and everything to do with an emperor's surname, a religious calendar, a train, and a marketing meeting.

KEY PEOPLE & FACTS

Fan Li (c. 475 BC) — earliest known treatise on fish farming, written about common carp
Tang dynasty (618–907 AD) — carp banned because it sounded like the emperor's name Li; farmers switched species and accidentally invented polyculture
Spencer F. Baird & Rudolph Hessel, US Fish Commission — 345 carp imported from Germany in 1877; in 1882, 260,000 carp went by rail to 298 of 301 congressional districts
Geosmin — the earthy compound humans detect at roughly 5–15 parts per trillion; fish farms purge it in clean water before harvest
Lee Lantz (1977) — renamed Patagonian toothfish "Chilean sea bass"; the FDA accepted it in 1994
Illinois DNR (2022) — rebranded invasive carp as "Copi"
Prof. Paul Rozin, UPenn — disgust is largely learned, appearing roughly between ages 4 and 8
