In part because Somalia has 3,025 kilometers of coastline, fishing was a sector with excellent economic potential. Considerable attention had been paid to this sector, especially since the 1974 drought, when 15,000 nomads were resettled in fishing cooperatives. Data in the latter half of the 1980s showed improvement in the fishing industry. Food and Agriculture Organization estimates of total tons of fish caught and processed rose from 16,900 in 1986 to 18,200 in 1988, an increase that resulted from the development of a national fishing fleet. Yet fishing remained a largely unexploited sector, contributing less than 1 percent of GDP in 1990.
