Fresh fish is not a staple for the country as a whole but is much prized in Freetown and other parts of the Peninsula. The fishing industry, which once was confined to inshore waters, has spread into the middle waters and includes canoe, industrial, freshwater, and shellfish fisheries. Total fish and shellfish production in 2000 was 74,730 tons, with bonga shad accounting for 21,621 tons. Shrimp is the main export; fisheries exports were valued at $14.6 million in 2000. The government has a joint venture agreement with Maritime Protection Services Sierra Leone Ltd., the purpose of which is to prevent poaching, protect artisanal fishing, increase revenue, and conserve maritime resources.
