Mowi Scotland is implementing an innovative approach at its Loch Etive salmon farming sites by synchronizing fallow periods across all locations within the loch.
This new strategy, which involves six-month growth cycles, aims to enhance the sustainability and efficiency of Mowi’s operations. By coordinating these fallow (empty) periods, the company expects to significantly improve the control of sea lice populations, which are less likely to thrive in the loch’s naturally brackish waters.
The synchronized fallowing is part of a broader production plan that Mowi Scotland has introduced following the acquisition of several farming sites in Loch Etive from Dawnfresh Farming in 2023.
The first fish were introduced to the loch under this new system in February 2024. These post-smolt salmon will be used to stock Mowi’s larger sites in the Small Isles, Loch Linnhe, and Loch Seaforth.
Mowi is confident that this synchronized approach will not only enhance the control of sea lice but also reduce the environmental impact of its farming activities. With less standing biomass on-site during fallow periods, there will be a reduction in feed usage and organic waste, which in turn will lessen the benthic footprint on the seabed.
This initiative marks a shift from traditional land-based post-smolt production, which is often associated with high construction costs and energy consumption. Mowi sees the Loch Etive strategy as a sustainable alternative that aligns with its commitment to environmentally responsible aquaculture practices, according to a release from the company on Friday.
