I was deeply disappointed by your article on salmon farming (News, October 28).

The outbreak of seasonal flu and a minor, resolved issue with the FDA happened 13 months apart. They are linked only by the views of one anti-fish-farming campaigner described by a judge in the Supreme Court of British Columbia as "akin to a zealot. Virtually anything that conflicts with his view and vision is wrong - Neutral facts will lead him to jump to irrational conclusions."
