PARIS (AFP) — Populations of migratory river fish collapsed by 76% on average in the last 50 years, according to a report by conservation groups Tuesday, warning the “catastrophic” declines could impact people and ecosystems around the world.
“Catastrophic losses in migratory fish populations show we cannot continue destroying our rivers,” said Arjan Berkhuysen, managing director of the World Fish Migration Foundation.
“This will have immense consequences for people and nature across the globe. We can and need to act now before these keystone species are lost for good.”
Migratory fish such as salmon, trout and Amazonian catfish support the livelihoods of millions of people around the world, researchers said.
