The brackish waters of the Little Blackwater and Blackwater Rivers support a variety of fresh and saltwater fish species and crabs. Fishing and crabbing access is restricted to boats, the causeway across the Little Blackwater River, and the Rt. 335 Bridge. No fishing is allowed from the Wildlife Drive. All parking rules must be strictly followed when fishing in these areas. Boat launching is restricted to the public boat ramp at Shorters Wharf (with trailers), and the Rt. 335 Bridge canoe/kayak launch (no trailers — carry in only). Boats are allowed within refuge boundaries from April 1 – September 30. A valid State of Maryland fishing license is required, and all State of Maryland fishing and crabbing regulations apply. Fishing and crab lines must be attended at all times. Fishing on the refuge is fair for species such as striped bass, white and yellow perch, black crappie, and bullhead and channel catfish. Carp, bluegill, and pickerel are also found in the rivers. The Little Blackwater River is a very popular spot for the spring run of white perch, as well as late summer crabbing. Fishing for largemouth bass is generally poor.
