Expansion of cod farming worries green groups

According to the newspaper, the expansion of the cod industry in Norway has prompted fears from green groups that it will lead to more escapes and contamination.Norway, which accounts for around 80 per cent of world farmed cod production, increased its production by 59 per cent from 10,375 tonnes in 2007 to 16,523 tonnes in 2008. "We are very concerned at the current levels of cod farming," said Nina Jensen, of WWF Norway. More than 200,000 cod escaped from Norwegian farms last year, the Guardian wrote.
