Climate change is making fish smaller and smaller
Fish in European waters have lost half their body mass in the space of a few decades due to climate change, according to a study by the French institute Cemagref published Monday in the United States.
Researchers from this public institute specializing in the sustainable management of water and land studied fish populations in European rivers, as well as in the North Sea and the Baltic Sea. Their conclusion, published in the journal "Proceedings of the National Academy of Sciences" is that different species of fish have lost an average of 50 pc of their body mass over the past 20 to 30 years and that the total mass of fish present in European waters fell by 60 pc. Smaller species tend to take a proportionately larger place in seas and rivers, explained the study's lead author, Martin Daufresne. (NLE)
