Local fish species in U.K. waters predicted to decline by 2050

The transcript discusses the impact of rising sea temperatures on fish species in British waters. Cold water fish like cod may decline, replaced by warm water species such as the European anchovy. The number of Atlantic bluefin tuna is increasing, possibly due to warming waters, which have also made mackerel dominant off Scotland's West Coast. The Northern Hague has repopulated the North Sea. Fish may evolve to have smaller bodies as oxygen levels decrease and they need to swim further for food.
