The scientific advice informing measures for 2026 is provided by the Technical Group on Salmon (TEGOS), in its Status of Irish Salmon Stocks in 2026 with Catch Advice for 2026, published at www.fisheriesireland.ie/publications. Appendix IV of that report provides a river-by-river assessment.
Stocks are assessed by TEGOS over the most recent five-year period, using an established, science-based methodology that is applied consistently across all salmon rivers. This methodology draws on best available information from a range of sources, including fish counter data, catch data and catchment wide electrofishing (CWEF) surveys.
The CWEF survey undertaken by Inland Fisheries Ireland in summer 2025 in the Boyne indicate that salmon fry levels are well under that considered to indicate a healthy stock. The TEGOS report indicates that the Boyne salmon stock is meeting only 10% of its conservation limit and scientific advice for 2026 is that the stock remain closed to fishing.
There are multiple actions underway by IFI to address pressures on the Boyne salmon stock. These include hydromorphological pressures associated with historic arterial drainage, water quality issues primarily associated with agriculture, and climate-related pressures affecting survival. IFI has a central role in researching and evaluating the impacts of such pressures as well monitoring and reporting on the status of our salmon stocks, including through the designation of the Boyne as a key index site under its Climate Change Mitigation Research Programme.
IFI has supported a number of habitat rehabilitation projects in the Boyne catchment. These include work on tributaries including the Enfield Blackwater, Garr, Knightsbrook, Mongadh, Skane and Stoneyford Rivers. Measures undertaken include habitat restoration, rehabilitation of spawning areas, fencing to exclude livestock, the introduction of solar drinkers and riparian tree-planting to improve shading and climate resilience. IFI has indicated that support for such remediation projects will continue in the Boyne in light of the concerning status of salmon stocks in the river.
IFI has also recently opened a new call under the National Barrier Mitigation Scheme to support projects that improve river connectivity by removing or reducing the impact of man-made barriers. This funding opportunity is open to stakeholders along the Boyne and IFI has advised that it is happy to engage with all interested parties. A number of project proposals are currently in development within the River Boyne Catchment, including at locations on the River Deel, Kells Blackwater, Knightsbrook and Skane Rivers.
Atlantic salmon are a qualifying interest of the Boyne and Blackwater Special Area of Conservation (SAC) under the EU Habitats Directive, however, the preparation and publication of management plans for Special Areas of Conservation (SAC) is a statutory process led by the National Parks and Wildlife Service and operates separately from fisheries management arrangements.
