The three year long investigation took place around the former Isle of Ewe fish farm on the north west coast.
The company has said in a new statement that throughout the operational life of fish farms, environmental effects are limited especially when managed by a robust regulatory framework underpinned by environmental standards that ensure the protection of the seabed and biodiversity.
However, until the study, limited information was available on how seabeds respond following the cessation of fish farming operations.
The aim of the probe, which was conducted alongside delivery partners Benthic Solutions and Applied Genomics, and supported by Salmon Scotland, was to assess the environmental condition and trajectory of seabed recovery following the closure of the Loch Ewe fish farm.
The project included monitoring seabed samples, habitat mapping, and an eDNA analysis covering a much bigger biodiversity profile.
Mowi said: “Over three years, the project concluded that the seabed can and will recover quickly. In 2020, 67% of the samples met the conditions for ‘Good Ecological’ status. In 2021, this percentage increased to 80%; in 2022, it increased to 93%; and in 2023, 100% of the samples met the conditions for ‘Good Ecological’ status.”
Reflecting on the results, Connie Fairburn, Senior Environmental Analyst at Mowi Scotland said: “There are many misconceptions about the environmental impact of the aquaculture industry.
However, this project provides solid evidence that sea beds can recover upon cessation of fish farming operations.”
