60% of fish species could be unable to survive in current areas by 2100 – study

Warming water temperatures lower water oxygen levels, putting embryos and pregnant fish at risk, researchers say

Sixty per cent of studied fish species will be unable to survive in their current ranges by 2100 if climate warming reaches a worst-case scenario of 4-5C (7.2-9F) above pre-industrial temperatures, researchers have found.

In a study of nearly 700 fresh and saltwater fish species, researchers examined how warming water temperatures lower water oxygen levels, putting embryos and pregnant fish at risk.
