ARGUIN ISLAND

island off the coast of Mauritania; it lies about 50 miles (80 km) southeast of Cape Blanc, in a sheltered Atlantic inlet (Arguin Bay). The island (4 by 2.5 miles [6 by 4 km]) was incorporated into the newly independent Mauritania in 1960. Aridity and poor anchorage have prevented the establishment of permanent settlements on it, but the coastal reefs, known as the Arguin Banks, are major fishing grounds. The island is also an important site for turtle fishing and produces gum arabic.
