Scottish salmon is facing a challenge to its reputation as one of Britain’s best loved everyday luxuries, with scares over diseases and sea lice, heavy use of pesticides and seal killing raising fears about its environmental impact.

A new fish-farming company called Fishfrom believes it can help solve the industry’s problem, and even partly solve future crises over food shortages. Its answer: take salmon farming entirely out of the sea.

It is planning to build a vast new warehouse on the west coast of Scotland where it hopes to farm salmon on dry land, cultivating thousands of tonnes of fresh salmon untainted by chemicals, sea lice and seal-control, in a self-contained facility run on renewable electricity.

That factory, at Tayinloan, just opposite the Hebridean island of Gigha, will be powered largely by solar panels and a small hydro scheme nearby, feed its salmon on its own supply of a specially farmed marine animal called ragworm, and will recycle nearly all the water it needs onsite.
