A Change of Fish

Cod, herring and haddock could migrate away from Scotland's west coast waters because of warming sea temperatures, according to researchers at the Scottish Association for Marine Science. Scientists predict the cold water species will vanish from the west coast by the year 2100. The researchers suggest the fish are already nearing "edge of their temperature tolerance range". However, they add that global warming will see other species replace them such as saithe, hake and whiting.

The paper's lead author, marine ecologist Dr Natalia Serpetti, said: "Even under the best case climate change scenario, cod and herring stocks were predicted to collapse off Scotland's west coast."
