Climate change may be stunting fish growth, a new study said. Fish sizes in the North Sea have shrunk dramatically, and scientists believe warmer ocean temperatures and less oxygenated water could be the causes. The body sizes of several North Sea species have decreased by as much as 29 percent over a period of four decades, according to the report published in the April issue of Global Change Biology. The report presents evidence gathered as researchers followed six commercial fish species in the North Sea over 40 years. Their evidence showed that as water temperatures increased by 1 to 2 degrees Celsius, an accompanying reduction in fish size was observed. It is generally accepted among scientists that decreased body size is a universal response to increasing temperatures, known as the ‘temperature size rule,’ the report said. But before this report, led by scientists at Scotland’s University of Aberdeen, there […]
