Migratory Fish in Crisis: UN Report Highlights 30 Species

0:00On March 24th, migratory freshwater fish that travel huge distances through rivers and lakes are in serious trouble from dams, pollution, and overfishing, which block their paths to breeding spots. A new United Nations report highlights 30 key species, like the Golden Masier and Goonch Catfish, as top priorities for worldwide protection. Scientists studied over 15,000 species and found their populations have plunged by about 81% over the last 50 years. These fish make up half of all fish kinds and come in wild varieties, from giant catfish weighing over 650 pounds to Golden Dorado, swimming thousands of miles in South America. The report builds on earlier work from 2011 when only 3,000 species got checked, but now data from the International Union for the Conservation of Nature covers far more ground. They feed around 200 million people globally and support countless livelihoods, plus hold deep cultural value in places like the Himalayas.

1:01Experts stressed that dams fragment rivers every kilometer in Europe alone, wearing out the fish and leaving them weak against predators and disease. The United Nations once these 30 species added to its 1979 treaty on migratory animals, which has already saved things like the. Saiga antelope from the brink. That means countries teaming up across borders to fight over fishing and fix habitats. With better coordination, these vital swimmers could bounce back, securing food and traditions for millions around the world.
