Thousands of fish are facing a “catastrophic” decline, threatening the health, food security and livelihoods of millions of people around the world.The latest research shows that now one third of all freshwater fish.
According to reports issued by 16 global conservation organizations on Tuesday, there are 18,075 species of freshwater fish inhabiting our oceans, accounting for more than half of the world’s total fish species and a quarter of all vertebrates on the planet.ThisThis is not only vital to maintaining the health of the planet, but also vital to maintaining the economic prosperity of global communities.
The researchers said in the “World̵
Researchers say that despite their significance, freshwater fish have been “underestimated and ignored.” Today, freshwater biodiversity is declining twice as fast as oceans and forests.
80 freshwater species have been declared extinct-16 in 2020 alone.
“The natural crisis in the world is the most serious in our rivers, lakes and wetlands, and the most obvious indicator of damage to us is the rapid decline of freshwater fish populations. They are the aquatic version of canaries in coal mines, and we must pay attention to this. A warning.” said Stewart Orr of the World Wildlife Fund. “Although freshwater fish are important to local communities and indigenous peoples around the world, they are always forgotten and not included in development decisions regarding hydroelectric dams or water use or construction on floodplains.”
In the past 50 years, migratory species have fallen by more than three-quarters, while the number of larger species called “big fish” has fallen by 94%, which is “catastrophic.”
Freshwater ecosystems face a comprehensive and devastating threat, including habitat destruction, hydroelectric dams, excessive irrigation water, various pollution, overfishing, the introduction of invasive species, and ongoing climate change.
Organizations such as the World Wildlife Fund, Global Wildlife Conservation Organization and Nature Conservation Organization are now calling on governments to implement “emergency recovery plans” to preserve freshwater biodiversity. They recommend protecting and restoring rivers, water quality and important habitats-eliminating the damage caused by overfishing.
Orr said: “Freshwater fish are vital to human health and the freshwater ecosystems on which all people on land and all people depend.” “It’s time for us to remember.”
