Rising sea temperatures will threaten fish in equatorial areas in the future, jeopardising food supply for those regions.
Researchers have found that equatorial fish are not used to fluctuating sea temperatures, so will be greatly impacted by rises of 2-3C.
At warmer temperatures fish lose scope for performance. In the wild, this would limit activities crucial to survival, such as evading predators, finding food, and generating enough energy to breed.
This will have great implications for the large number of developing countries that lie in the equatorial zone, where fish are crucial to the livelihoods and survival of millions of people.Read more at James Cook University
