Small fish species may eventually face extinction as warming oceans increase pressure on their survival and hamper their ability to adapt
Herrings are among the species of fish studied by researchers, who found climate change is impacting their size. Pic APPopular dinner-table fish including anchovies, herrings and pilchards could shrink because of climate change, new research suggests.
. Professor Chris Venditti, an evolutionary biologist at the University of Reading, and co-author of the study said:"Warming waters are a double whammy for fish, as they not only cause them to evolve to a smaller size, but also reduce their ability to move to more suitable environments. "Our research supports the theory that fish will get smaller as oceans warm under climate change but reveals the worrying news that they will also not be able to evolve to cope as efficiently as first thought.
"With sea temperatures rising faster than ever, fish will very quickly get left behind in evolutionary terms and struggle to survive."This has serious implications for all fish and our food security, as many of the species we eat could become increasingly scarce or even non-existent in decades to come."
