Aquaculture for all

Mowi's smolt sites set ASC precedent

Atlantic Salmon Certification +3 more

Mowi Scotland has become the first aquaculture company in the world to achieve Aquaculture Stewardship Council (ASC) certification for its freshwater loch smolt production.

The company's smolt production sites on Loch Lochy and at Glenfinnan have achieved certification against the Aquaculture Stewardship Council's revised trout standard.

Rory Campbell, Mowi's technical manager, explains: “This is a significant milestone for our business. Loch Lochy and Glenfinnan are both freshwater loch farms that, along with our recirculating aquaculture facilities, provide for a vital part of our salmon’s lifecycle before entering the sea. Both sites are the first freshwater farms in the world to be audited against a revised ASC Trout Standard that now recognises the production of salmon smolts in freshwater lochs. By achieving ASC certification at these freshwater loch sites it now allows us to have a pipeline of ASC certified smolts for our seawater sites and enables us now to push on with our plan to achieve ASC certification across our business.”

Samuel Clegg, certification manager, describes the process: “The audits were carried out in February. Two auditors spent two days auditing each farm. One auditor was really focused on technical information and the other auditor looked into personnel issues such as health and safety, human resources and payroll. As part of the audit process, many of our farm technicians at site were interviewed, along with our fish health professionals who care for the fish at these sites. The whole process is deeply involving for all those involved with the standard covering a multitude of different technical, social and environmental areas.

“There are hundreds of criteria within the Trout Standard and you have to pass every single one in order to get accreditation. It really does take the whole team to achieve this standard, the auditors look at every aspect of our business including our relationships with stakeholders local to the farms.”

Both sites will need to be audited annually. The rest of the year will see many more audits by the ASC as Mowi strives to achieve 100 percent accreditation for all its farms by 2025.
