Oxygen levels in fish & global warming

A study which aims to predict which species of fish are most at risk from global warming and pollution has been conducted by researchers.

The team from the EARA member Radboud University, Nijmegen, Netherlands, and the University of Montpellier, France, compiled data to see whether water temperature influences oxygen levels in 195 different species of fish.

They reported that larger fish and fish with larger cells are more sensitive to a lack of oxygen, but only in warm water. They also found differences between freshwater fish and saltwater fish.

"Once we have identified these rules for fish, we can ultimately predict which fish species are most at risk from environmental change." says researcher Wilco Verberk.
