Rhode Island's traditional manufacturing economy has diversified and is now also based on services, trade (retail and wholesale), and finance. In spite of this, many of the products for which Rhode Island is famous are still being manufactured. These include jewelry, silverware, textiles, primary and fabricated metals, machinery, electrical equipment, and rubber and plastic items. Tourism and gambling are also important. Agriculture is relatively unimportant to the economy. Most of the farmland is used for dairying and poultry raising, and the state is known for its Rhode Island Red chickens. Principal crops are nursery and greenhouse items. Commercial fishing is an important but declining industry. Narragansett Bay abounds in shellfish; flounder and porgy are also caught. Naval facilities at Newport contribute to the state's income.
