Jill at La Vida Locavore exerpts from a book Bottomfeeder: How to Eat Ethically in a World of Vanishing Seafood by Taras Grescoe:
Here are some shrimp facts from the book:
- In 2006, Americans ate 1.3 billion lbs of shrimp, or 4.4 lbs per person.
- As bad as shrimp farming is, wild-caught shrimp are pretty awful too: for every one pound of shrimp caught by trawler, they kill and throw away 10 pounds of "bycatch" (other species they weren't fishing for).
- Chain restaurants favor the uniformity of farmed shrimp over wild-caught shrimp, which can be more varied.
- 85% of shrimp sold in the U.S. is imported.
- 3/4 of the world's shrimp production comes from developing nations like Vietnam, India, Indonesia, Thailand, Sri Lanka, and China.
- China's the top producer of shrimp, followed by Thailand.
- China supplies 70% of the planet's farmed fish.
- In the U.S. one in every five fish is from China.
- For each pound of farmed shrimp, it takes two pounds of wild-caught fish flesh. These are ground up and turned into pellets.
- Shrimp have been turned into cannibals. A major ingredient in the pellets they eat is ground-up shrimp heads.
- Individual shrimp farmers rarely do well financially, facing low prices for shrimp, high feed costs, and high risk of being wiped out by disease.
- Shrimp farms do not effectively create jobs. In India an acre of rice paddy can employ 14 people but an acre of shrimp ponds employs 1.
- Plants that process farmed shrimp hire many workers to behead and devein shrimp. In India, these workers make (on average) $35/month.
- "In Louisiana, which does rigorous testing of its own, the antibiotic chloramphenicol, known to cause leukemia and aplastic anemia, was found in nine percent of all samples." - p. 159
- Mangroves, which are being destroyed by shrimp farming, form a natural barrier against hurricanes and tsunamis. They "are among the most productive ecosystems on earth, as well as the most efficient carbon sinks we know of." - p. 160
- "38% of mangrove loss worldwide can be attributed to shrimp farming." - p. 160
- "In Ecuador, a major supplier of farmed shrimp to American chain restaurants, almost 70 percent of mangroves have been razed since the coming of shrimp farms." - p. 160
- In 1990, a flesh-eating virus spread from Mexican shrimp farms to wild blue shrimp, wiping out the blue shrimp in the upper Gulf of California.
- "An epidemic of antibiotic-resistant cholera has been documented among Ecuadorean shrimp farm workers." - p. 164
