Total production in aquaculture in Iceland has fluctuated somewhat between years. During the period between 1985 and 1990 production went from a few hundred tonnes to over 3,000 tonnes. From 1991 to 2002 production remained at approximately 3,000-4,000 tonnes, and then increased substantially with increased salmon farming in 2003-2006, when the sector shrank again and the total production went down to 4,000-5,000 tonnes. In 2009, the production was approximately 5,000 tonnes and the total value approximately ISK 3bn. In 2010, production increased again and was just under 6,000 tonnes with a value of ISK 5bn. It is believed that around 230-250 people were employed in aquaculture in just under 30 companies.
