The Norwegian Institute of Public Health has published an overview of sales of various drugs used in fish breeding in Norway from 2001-2007.
The sales are shown in kilograms of active ingredient; antibacterials, anaesthetics, anthelmintics and treatments for sea lice and fungi. The figures are based on sales from wholesalers to pharmacies and from feed mills to breeders.
After an increase in sales of antibacterials from 2002-2006, sales in 2007 returned to levels seen in 2001. Prescription-based statistics from the Norwegian Food Safety Authority for the period 2000-2006 show that this increase can be blamed on new breeding species, especially cod. However, the increase in use for cod was positively correlated to the increase in biomass cod produced.-Norwegian Institute of Public Health
