FEARS have arisen over the future of fish suppers after a study found cod and haddock are under threat.
The British Antarctic Survey looked into antarctic species and how they are fighting for survival in changing oceans.
The team discovered larger marine species face extinction as water temperatures rise and oxygen levels drop.

Professor Spicer from University of Plymouth, who has spent more than 30 years examining the effect of climate change on marine organisms, said: “Over the last 50 years, the oxygen in our oceans has decreased by around 2-5% and this is already having an effect on species’ ability to function. Unless they adapt, many larger marine invertebrates will either shrink in size or face extinction.

Dr Simon Morley, a marine ecologist at BAS, added: “Marine animals thrive in the Southern Ocean but life in these freezing waters has led to the evolution of many distinct characteristics. These ‘strategies’, which allow animals to survive in the cold, are expected to make many Antarctic marine invertebrates and fish vulnerable to the impact of climate change.”
