Stop Salmon Farming, For Good (Ullapool Community Event, March 2024)

Stop Salmon Farming for Good

What is wrong with open cage salmon farming in Scotland and what do we do about it? “Stop salmon farming, for good".  We want:

• Local communities having the final say on all salmon farm developments and the right to review and amend the planning permissions for all existing salmon farms • An end to the dumping of salmon farm sewage, chemicals, plastic, and parasites in our sea lochs • All government grant funding and subsidies being given to overseas salmon farming corporations to be diverted into our local community action and development groups • Vibrant and diverse local economies that don’t require us to destroy the places we live and in which we have more of a say and share in more of the benefits

Wild Atlantic salmon at risk of extinction amid ‘devastating’ decline

The Times

Climate change, pollution and parasites caused by farming are among the reasons for decline in wild salmon in Scotland. Figures show an alarming deterioration in Scottish rivers, leading to measures banning anglers from keeping their catches.

The reality gap: An examination of Scottish farmed salmon

WildFish

This report first gives an overview of the various marketing tools used by the Scottish salmon farming industry to represent farmed salmon as a sustainable, healthy and eco-friendly protein choice. It then examines the environmental and welfare performance of Scotland’s seven salmon farming companies, all widely used in the hospitality and retail sectors.

Follow-up inquiry into salmon farming in Scotland

Rural Affairs and Islands Committee

In 2023, the RAI Committee agreed to undertake a follow-up inquiry into salmon farming at the earliest opportunity and this inquiry commenced in April 2024. The RAI Committee's inquiry focused on the implementation of the main recommendations made by the REC Committee, spread across four key themes:

  • fish health and welfare;
  • environmental impacts;
  • interactions between wild and farmed salmon; and
  • salmon farm consents and planning.

Scottish salmon farms seek growth despite mounting fish deaths and environmental concerns

Mongabay

Scotland is the world’s third-largest producer of farmed Atlantic salmon (Salmo salar), after Norway and Chile. The industry is seeking to significantly increase production in Scotland, driven by growing export demand.However, it faces ethical concerns over mounting fish mortality, as well as environmental concerns about pollution, the proliferation of sea lice affecting wild salmon, and opposition from several local communities.Industry members acknowledge the challenge of growing salmon amid rising sea temperatures, but say Scottish salmon farms have made progress in managing sea lice and other health challenges.

Pathogens from salmon aquaculture in relation to conservation of wild Pacific salmon in Canada

Science Advances

The spread of pathogens from farmed salmon is a conservation concern for wild Pacific salmon in British Columbia (BC), Canada. Three pathogens are prevalent in farmed Atlantic salmon in BC, spill over to wild Pacific salmon, and are linked to negative impacts on wild salmon: Piscine orthoreovirus, Tenacibaculum spp., and sea lice (Lepeophtheirus salmonis). Molecular screening of infectious agents in farmed and wild salmon and environmental DNA highlights a further 4 agents that are likely elevated near salmon farms and 37 that co-occur in wild and farmed salmon. Pathogens likely affect wild salmon indirectly by mediating migration, competition, and predation. Current net-pen aquaculture practices pose these risks to numerous populations of all species of wild salmon in BC, most of which are not covered in Government of Canada science and advisory reports. Climate change, pathogen evolution, and changes to disease management and aquaculture regulations will influence future risks. By Martin Krkosek, Andrew W. Bateman, Arthur L. Bass, William S.

How mariculture expansion is dewilding the ocean and its inhabitants

Science Advances

The world’s oceans are largely free from intensive farming, but momentum to intensify and expand mariculture—the cultivation of aquatic organisms in the ocean—is growing. Despite optimism that mariculture will create economic and nutritional benefits for humans, it can also generate a host of risks, including environmental degradation, harms to wildlife integrity and welfare, captivity effects, and shifts in how humans view the nonhuman world. Collectively, we refer to these four types of risks as 'dewilding.' In this systematic review, we searched Scopus and Web of Science for recent literature documenting mariculture’s dewilding impacts to organize and collate this evidence under one unified framework. We find that mariculture’s dewilding impacts are consistently documented, though often in isolation, and that captivity and conceptual dewilding impacts are recognized as potential harms far less than impacts on the environment and wildlife. Future work examining mariculture’s dewilding impacts will be paramount to guiding human decision-making and activity going forward. By Becca Franks, Chiawen Chiang

What to Know About the Salmon on Your Plate

NPR

Norway is the largest exporter of salmon in the world. And while some of those fish are wild-caught, many are raised in 'fish farms'- large cylindrical pens made of nylon in the open water. Sometimes these farmed fish escape, mixing with the local population and causing ecological issues. We see farmed fish in a Norwegian fjord and hear about potential solutions to the problem.
