Custom Saltwater Flies by Captain Charles Crue
As the name implies this is a fly that imitates a small crab.
Cast it out in shallow water and let it sink then slowly strip it to give the appearance of a crab moving on the bottom.
Captain Crue founded Channel Edge Charters in 1996. His guide specialty was fly fishing for striped bass and bluefish on the Merrimack River and Plum Island inshore waters. After providing purchased flies for a short time he began tying his own versions of the most successful flies for his clients to use during his charters. This evolved into creating many of his own fly patterns, some of which are included in fly tying books and published articles.
