With Eritrea's independence from Ethiopia, access to about 1,011 km (628 mi) of Red Sea coastline was obtained, making Ethiopia a landlocked nation. Because Eritrea now controls the coastline, long-term prospects for development of offshore fishing and oil are good. The total catch rose from 475 tons in 1993 to 12,612 tons in 2000. The Eritrean navy patrols the coastal waters to limit poaching by unauthorized non-nationals. The development of local fishing will decrease the dependence on foreign food aid, even though fish has not been a major source of Eritreans' protein intake.
