Freshwater fish are dying dramatically, and the situation is worrying

A report on the “catastrophic” species extinction of freshwater fish has been reported, with 80 species of the world already extinct, 16 of them last year, in a single year.

Freshwater fish are a source of food for millions of people and a livelihood through fishing and ornamental fish trade, the BBC news portal wrote.

Pollution, overfishing, the construction of dams and the drying up of rivers, draining wetlands are dramatically reducing the number of fish. According to the report, the migratory fish population has shrunk by three-quarters in the last 50 years. During the same period, the population of larger-bodied fish species became 94 percent smaller.

The World’s Forgotten Fishes report was produced by 16 environmental organizations, including the World Wide Fund for Nature (WWF) and the London Zoological Society (ZSL).

According to the WWF, the main cause of fish deaths is the poor condition of rivers, which is mostly to blame for pollution, dams and canals.

WWF staff member Dave Tickner told the BBC that while freshwater is one of the most dynamic habitats on Earth, it shows a picture of catastrophic destruction around the world.
