The Impact of climate change & fish farming on Atlantic salmon

The Conclusion of new research show that climate change and fish farming has had an impact on the Atlantic salmon in Northern Spain. The Combination of climate change and the introduction of farmed Atlantic salmon into wild populations is shaping regional genetic patterns of Atlantic salmon in Northern Spain.

The research was carried out over 20 years and the data was obtained from salmon DNA, stocking of fish for farming and climate change were analysed from five rivers, every 5 years. This was to determine the relative importance of climate and stocking practices on the population structure and the genetic patterns. The study was financially supported by the EU INTERREG project.
