Sardines move north due to ocean warming

Sardines, anchovies and mackerels play a crucial role in marine ecosystems, as well as having a high commercial value. However, the warming of waters makes them vanish from their usual seas and migrate north, as confirmed by a pioneering study analysing 57,000 fish censuses from 40 years. The researchers warn that coastal towns dependent on these fishery resources must adapt their economies.
