The relative importance of Chesapeake Bay and Atlantic fisheries to Virginia's economy has lessened considerably in recent decades, although the state continues to place high in national rankings. In 1998, Virginia's commercial fish landings totaled 591.9 million lb (3rd in the US), worth $112.7 million (7th). Landings at the Reedville port in 1998 totaled 509 million lb, valued at $42.6 million. The bulk of the catch consists of shellfish such as crabs, scallops, and clams, and finfish such as flounder and menhaden. The blue crab catch totaled 33 million tons in 1998, or 15% of the US total. Both saltwater and freshwater fish are avidly sought by sport fishermen. A threat to Virginia fisheries has been the chemical and oil pollution of the Chesapeake Bay and its tributaries. In 1998, the state issued 632,179 fishing licenses.
