Shrewsbury Rocks is a premier saltwater fishing destination located off Monmouth Beach, New Jersey. This expansive natural rock formation is the largest of its kind in the mid-Atlantic region, creating a vital oasis of structure in the otherwise featureless stretch of ocean between Sandy Hook and Shark River Inlet. The area is composed of greensand sandstone, with some formations rising 20 feet or more off the bottom. Depths range from approximately 14 to 55 feet, with some outer edges reaching nearly 60 feet where it leads to the Rattlesnake grounds. The location is marked by two distinct green navigation buoys, known locally as the "Can" and the "Gas Can." This complex underwater terrain attracts a tremendous diversity of marine life year-round, supporting fisheries for striped bass, bluefish, fluke, black sea bass, and tautog. Its proximity to several inlets makes it a popular and accessible destination for both private and charter boats.
