Although most shrimp sold in the U.S. comes from farms overseas, you can buy fresh, wild American shrimp at some farmers' markets along the Gulf Coast from April through January. These shrimp tend to be especially firm and tasty, and, unlike farmed varieties, they're antibiotic-free. You can also buy frozen wild shrimp at supermarkets. Look for the new Wild American Shrimp certification label.
