Aquaculture in Morocco started in the 1950s and was largely based on the culture of oysters in one of the large lagoons along the Atlantic Ocean coast. The total production increased from 1 463 tonnes (1994) to 2 793 tonnes (1999), and then decreased to 1 538 tonnes in 2003 and 1 698 in 2004. This production represents only 0.19 percent of the total fisheries production.
