Although the more than 300 species of fish found in Bahraini waters constitute an important food source for much of the population, local fishing and pearl diving have declined because of industrial pollution. The catch totaled 11,718 tons in 2000. The government operates a fleet of seven trawlers. By encouraging traditional angling, giving incentives to fishermen, improving fishing and freezing equipment, and establishing cooperatives, the government is attempting to increase the annual catch. There is a modern fishing harbor at Al-Muharraq which provides docking and landing facilities, storage areas, an ice plant, and a water supply.
