Because bass and other game fish feed heavily on crawfish, using crawfish lures only makes good sense. So how do top anglers determine the best lure to use?
Fish love crawfish.
That is the simple reason why so many lures are shaped like crawfish, imitate the crustaceans' movements or come in crawfish color patterns. For anglers, the lure choices can seem overwhelming. The best lure for the job depends on the kind of fish an angler plans to target, the character of the places he plans to fish and the techniques he likes to use.
Probably no crawfish-imitating lure is more widely loved than a Rebel Crawfish, and few lures of any sort have been used to catch more different kinds of fish. Five models cover the gamut of sizes and run to a broad range of depths, but all work best when anglers simply cast them out and reel them back.
Rebel Deep Teeny Wee-Crawfish wobbled along gravel bottoms in tumbling streams are fabulous trout catchers. Big Craws, nearly twice the size of their smallest cousins, work better as bass baits and are widely used in waters ranging from tidal rivers to mountain lakes. In-between, the original 2-inch-long Rebel Wee-Crawfish is the ideal size for casting in smallmouth streams or walleye rivers.
For bass specialists who want to dig deeper than Rebel Craws dive or who desire a specific type of action, many classic crankbaits come in awesome crawfish color patterns. A red crawfish Bomber Fat Free Shad will let an angler crank a hump that’s more than 15 feet deep, while a crawfish Cotton Cordell 
Grappler Shad will provide an ultra-tight wiggle that remains true no matter how fast he cranks the handle.
For fishing under grass mats, where crawfish often congregate, or in thick woody cover, many anglers opt for jigs, which they flip or pitch into any little gap in the cover. A BOOYAH Boo Jig dressed with a YUM Chunk is ideal for wrestling big crawfish-eating largemouths out of the thick stuff. A Boo Jig dressed with a Baby CrawBug is a better pick for pulling smallmouths or spots from among boulders.
Because so many types of fish dine on crawfish, numerous YUM soft-plastic offerings have been designed to look like crawfish, and they can be fished by using a host of different techniques. Beginning small and looking at just a few, 2-inch Wooly Beavertails fished on 1/16-ounce leadheads will catch everything from rock bass to crappie to trout. A little larger, 3-inch Wooly Hawgtails work great on 1/8-ounce leadheads and drop-shot rigs for smallmouths. On big northern lakes, smallmouth anglers will contend that no crawfish imitation is more important than a YUM Mega Tube dragged slowly across the bottom.
Not to be forgotten, of course, are YUM CrawBugs and Big Claws, realistic craw-shaped tubes and craw-worms, respectively. These offerings, which are most commonly fished on Texas rigs and often flipped or pitched into cover, look just like the real meal in the water.
