Weakfish, also known as sea trout, is a type of fish found in North American waters. The term "weakfish" derives from the fish's fragile mouth architecture and weak jaws, which make it easy to catch with a hook and line. Some synonyms for weakfish include sea trout, spotted weakfish, spotted sea trout, and gray trout. The spotted weakfish has a distinctive pattern of dark spots along its sides, while the gray trout has a more uniform coloration. Other common names for this fish include speckled trout, yellowmouth, and trout-perch. Weakfish are popular among recreational anglers and are also commercially harvested for food.
