The number of farms increased in the 1990s thanks, in part, to a government backed breeding programme initiated in 1992. However, the operation was not profitable and several of the country’s 40 farms went out of business. The country produced 500 tonnes of Arctic char in 1995 which had risen to 3,000 tonnes in 2009. Production decreased between 2004-2006 due to bacterial kidney disease and the prohibition of distribution of eggs and juveniles from some hatcheries. In 2008, the country exported 700 tonnes of whole fresh Arctic char, 20 tonnes of frozen char, approx. 600 tonnes of fresh fillets and about 500 tonnes of frozen fillets. The export value amounted to ISK 1,200 million in 2008. The export value of the species amounted to ISL 1,100 million in 2008. Most January-February 2013 | InternatIonal AquAFeed | 51
