What Is The ‘Hidden Truth’ About UK Salmon Farming?
Plant Based News • Oct 23, 2026
The short documentary Gaslit: The Hidden Truth About Salmon Farming in the UK sheds light on the environmental, ethical, and health issues plaguing the industry that are often hidden from the public. The film reveals that 100 percent of Scottish salmon sold in UK supermarkets is factory farmed, resulting in diseases, parasites, and large areas of flesh eaten away by sea lice. To treat these infestations, workers use toxic chemicals that pollute waterways and harm wildlife.
As part of Project Slingshot's "End Salmon Farming" campaign, the organization aims to educate the public about the cramped conditions, sea lice infestations, and environmental pollution associated with factory farming fish. Despite industry marketing portraying Scottish salmon as premium and responsibly farmed, the reality is far from it, with issues of welfare, environmental impact, and lack of oversight being major concerns. A complete overhaul of the regulatory system is deemed essential to address these issues and protect animal welfare.
