"Fish are the most diverse group of vertebrates, ranging from tiny gobies and
zebrafish to gigantic tunas and whale sharks. They provide vital sustenance to
billions of people worldwide via fisheries and aquaculture, and are critical
parts of aquatic ecosystems.
But fish around the world are getting smaller as their habitats get warmer. For
example, important commercial fish species in the North Sea have declined in
size by around 16% in the 40 years to 2008, while the water temperature
increased by 1–2℃. This “shrinking” trend is forecasted to significantly
exacerbate the impacts of global warming on marine ecosystems.
The link between warmer water and smaller size is well known, but poorly
understood. Our experiments keeping fish in warmer water offer some crucial
clues – and may help us learn how to prepare for a warmer future with smaller
fish."
