Animal rights campaigners have turned their attentions to improving conditions on Scottish fish farms.

Pet Rescue presenter Wendy Turner – sister of nineties golden girl Anthea – sat in a bath of cold water outside the Scottish Parliament to protest at the cramped conditions farmed trout and salmon endure.

She was joined by Green MP Robin Harper, who is a member of a Scottish Parliament committee carrying out an investigation into Scotland’s fish farming industry.

Ms Turner told reporters: “I don’t eat animals and I don’t wear them, so I’m against farming of any type.

“I’m particularly against any form of intensive factory farming and fish farming is the forgotten factory under the sea in this country.

“The conditions the fish are kept in, the way they are bred, the way they have to exist and the way they are slaughtered, is something that we would never put up with in a million years if it was other animals.”

Scotland is Europe’s second biggest salmon producer after Norway, with 356 sea cage sites in operation.

Most fish are bred for the table.
