An advertisement for Freedom Foods' salmon with the catchline "How many animals do you know with their own Olympic-sized swimming pool?", has been the subject of a complaint from a protest group.

The Salmon Farm Protest Group accused the RSPCA'a Freedom Foods scheme of misleading the public over the stocking density at accredited salmon farms, and complained to the Advertising Standards Authority.

At 15kg of fish per cubic metre, FF salmon are less intensively farmed than some, but protest group chairman Brian Sandison said that this still meant up to ten fish per cubic metre of seawater.
