"The longest migration of any freshwater fish species is the dorado catfish, which makes a migration of 7,000 miles from spawning in the foothills of the Andes to feeding in the Amazon estuary and back again."
"Freshwater species are especially vulnerable to harm caused by humans because pollution often drains into rivers and lakes, dams block vital waterways and overfishing decimates populations."
"Animal migration is one of nature's great wonders. Their journeys, which can cross multiple national borders and even continents, are extraordinary feats of timing and endurance."
"Migratory freshwater fish also underpin some of the world's largest inland fisheries and sustain hundreds of millions of people but are among the most imperilled wildlife on the planet."
Freshwater fish migrations are among the largest animal migrations on Earth, with species like the dorado catfish migrating 7,000 miles. However, freshwater fish populations have declined by 81% since 1970 due to pollution, dams, overfishing, and climate change. These species are crucial for sustaining inland fisheries and the livelihoods of millions. International cooperation is necessary to protect migratory fish and ensure their survival amid increasing pressures throughout their life cycles.
