In Ireland, the consumption of salmon has led to a dominant market share being held by farmed salmon, with a growing segment being organically farmed. These fish are reared in cages in shallow seawater, with practices aimed at reducing fish density, limiting antibiotic use, and employing natural methods to combat sea lice. However, concerns have been raised about the potential environmental risks, such as escapes leading to interbreeding with wild salmon and the use of toxic pesticides and feeds, which could negatively affect wild fish and shellfish. Despite these concerns, salmon farming remains a significant contributor to Ireland's economy, with 38,000 tonnes produced in 2021, generating €175 million in revenue and supporting 2,000 direct jobs. The industry is largely dominated by the Norwegian multinational MOWI, with a 80-85% market share. Critics argue that salmon farming may not be environmentally suitable for Ireland due to high mortality rates.
