The Scottish Information Commissioner has ordered the release of “confidential” information over salmon farming, reports The National.

The data watchdog ruled Scottish ministers “failed to comply” with regulations when they “wrongly withheld” facts about the import of fish eggs for the aquaculture sector.

Last year the annual economic value of Scottish salmon broke the £1 billion barrier and the sector’s 200-plus active farms support around 10,000 jobs.

But plans for further expansion have proven controversial, with critics citing large-scale mortalities of farmed salmon at some sites due to infestations of killer sea-lice, or efforts to eradicate it.
