The Angolare community of São Tomé supplies fish to the domestic market. In 2000, the catch was 3,500 tons. Between 1976 and 1983, substantial investments were made in fishing by the government, but the investment has not significantly contributed to GDP; rather, it has exacerbated a nearly unsustainable debt service burden. European Union (EU) vessels catch tuna in island waters under license. There are also fishing agreements with Angola and Portugal. Foreign assistance has focused more recently on artisanal fishing.
