Surge in ‘unsatisfactory’ salmon farm environmental monitoring

The report was co-published this week by the Salmon and Trout Conservation and animal campaign charity OneKind.

Over the course of 12 months Tescos and Sainsburys supermarkets, stocked with Scottish farmed salmon, were monitored against publicly available data about their origins by the two charities.

They found that much of the stocked salmon comes from open cage farms, which have reported raised levels of sea lice parasites and disease, significant premature mortalities and “unsatisfactory” levels of marine pollution, all of which are putting Scotland’s wild fish and local ecosystems at risk.
