Farmed shrimp are kept in pools on the coast, where the tide can refresh the water and carry waste out to sea. Ponds are prepared with heavy doses of chemicals such as urea, superphosphate, and diesel. Then the shrimp receive pesticides, antibiotics (some that are banned in the U.S., but used overseas), piscicides (fish-killing chemicals like chlorine), sodium tripolyphosphate, borax, and caustic soda.
Shrimp farmers have destroyed an estimated
38 percent of the world’s mangroves to create shrimp ponds, and the damage is
permanent. Not only do the mangroves not return long after production has ended, but the surrounding areas become wastelands. According to a Yale University research paper, shrimp farming has made certain areas of Bangladesh completely unlivable for people: “The introduction of brackish-water shrimp aquaculture… has, in turn, caused massive depeasantization and ecological crisis throughout the region.”
