"F" is for Fishing, commercial. With extensive estuaries and barrier islands, the coastal areas of South Carolina are important regional nurseries for fisheries. The state's commercial fisheries are characterized by small-scale, individual operators harvesting primarily shrimp, offshore finfish, blue crabs, and oysters. Shrimping is the state's largest fishery. The two major shrimp crops are brown shrimp, caught in early summer, and white shrimp, harvested in late summer and throughout the fall.
