Deep Sea Fish Growing Slower Due To Global Warming

Changes in ocean temperature have altered the growth rates of commercially harvested fish over the past century, according to a new study published in this week's early online edition of the Proceedings of the National Academy of Sciences (PNAS). Analyzing the ear bones of 555 commercially caught fish to determine age, the researchers, led by Ronald E. Thresher of CSIRO-Australia, report that warmer temperatures in the southwest Pacific Ocean have enabled shallow-water fish to grow faster, perhaps making them more resilient to commercial exploitation...
