As climate change continues to warm the world's oceans, a new study suggests the fish that inhabit them may, in response, shrink in size as much as 30 per cent in the next 30 years. The study, published in Global Change Biology, found that fish size drops about 30 per cent for every degree of ocean temperature increase. They can't regulate their own body temperature, which means their body temperature increases along with the water they live in. As body temperature increases, metabolic processes speed up, which increases oxygen requirements. These are the species Pauly says will be most likely to shrink in size as oceans warm.
