Climate Change Could Cause Fish to Shrink in Size

In the coming decades, warming ocean temperatures could stunt the growth of fish by as much as 30 percent, according to a new study in the journal Global Change Biology.The main driver behind this decline in size is that warmer water contains less oxygen.

So as oceans heat up, a fish’s metabolism accelerates to cope with the rising temperatures and they
