A jerkbait is a type of fishing lure designed to mimic the erratic movement of injured baitfish. Typically made of hard plastic, jerkbaits are often slender and have a lip that helps them dive to specific depths when retrieved. Anglers use a technique called "jerking" to create a stop-and-go action, which can attract predatory fish like bass and pike. These lures come in various sizes, colors, and styles, allowing anglers to match the local forage. Jerkbaits can be effective in both freshwater and saltwater environments, making them a versatile choice for many fishing situations.
