The Labour MP toured Bakkafrost Scotland’s Loch Roag salmon farm on Lewis, which provides well-paid, year-round jobs across the island.
Mr Murray praised the sector’s “immense contribution” to the economy and its “crucial” support for livelihoods.
He was joined by Western Isles Labour candidate Torcuil Crichton and welcomed to Loch Roag by Tavish Scott, chief executive of Salmon Scotland, and Iain MacIntyre, director of marine operations at Bakkafrost Scotland.
Scottish salmon is the UK’s largest food export, with recent HMRC figures showing that exports jumped by nine per cent to £306 million, driven by significant growth in the Asian and American markets.
Scotland's farm-raised salmon sector directly employs more than 2,500 people in Scotland and supports over 3,600 suppliers and an additional 10,000 indirect jobs.
In the Western Isles alone, the sector employs more than 400 people and contributes in excess of £150 million annually to the local economy.
Trade body Salmon Scotland is calling for an overhaul of the complex regulatory and planning system for aquaculture.
Through streamlined reforms, achieving additional sustainable growth for Scotland’s rural and coastal communities becomes possible, leading to the creation of more high-paid, high-skilled local jobs.
