Del Brown's Permit Crab

Del Brown’s Merkin Crab is one of the most iconic and influential saltwater fly patterns ever tied. Originally designed by the late permit pioneer Del Brown, this fly helped define modern permit fishing and has inspired countless variations since. The Merkin’s body—constructed from layered yarn trimmed into a crab shape—creates a realistic profile and sink rate that perfectly mimics a fleeing crab on the flats. Subtle rubber legs add lifelike motion, while the weight of lead eyes ensures the fly rides hook point up to reduce snagging. Effective throughout the Caribbean, Central America, and the Pacific, the Merkin remains a go-to choice for permit and other crustacean-feeding species.
