Oceana, an international marine conservation organisation, presented a report drafted by the Ministry of the Economy that indicates the national salmon farming industry used 325.6 tonnes of antibiotics over the past year, and 385.6 tonnes in 2007.
According to the official report, florfenicol (used in 56.7 per cent of the total, or 184 tonnes) and flumequine (in 9.9 per cent, or 32.2 tonnes) were the antimicrobials most used in 2008, among others.
Two years ago, florfenicol had been used in 37 per cent (143 tonnes) of the stock; and oxytetracycline in 23.1 per cent (89.3 tonnes), among other antimicrobials.
