Fish stocks continuing to fall as oceans warm, study finds

Losses in North Sea are among the world's biggest, according to US analysis

Fish catches have declined markedly and are likely to fall further, a study has found, with warming oceans to blame.

Around the world, fish populations have fallen over the past 80 years, although some species have shown greater resilience than others. Overall, catches of commercially important fish have fallen by just over 4%, but in some regions catches have plunged by about a third since early in the last century.
