Economic losses are driven by high mortality rates and the cost of sea lice control, while environmental costs include carbon emissions, local pollution, and the depletion of wild fish stocks. Social costs are primarily linked to poor fish welfare and the diversion of forage fish from human consumption in developing regions like West Africa. The authors argue that current intensive farming practices are a 'false economy' and recommend a transition to alternative feeds and improved husbandry standards.","ai_generated":true,"unit":"chanmar-000112#summary","date_modified":"2026-10-23"},"key_insights":[{"text":"The total private and external costs of salmon aquaculture across Norway, Scotland, Canada, and Chile from 2013 to 2019 are estimated at USD$47.3 billion, with approximately 60% (USD$28 billion) borne by producers and 40% (USD$19 billion) by wider society.","ai_generated":true,"unit":"chanmar-000112#insight-1","date_modified":"2026-10-23"},{"text":"High mortality rates represent a significant opportunity cost for farmers, totaling USD$15.5 billion across the four main producing countries since 2013.
