Fish species that undertake mammoth migrations through rivers, lakes, and ponds are facing a combined threat from dams, pollution, and overfishing preventing them from reaching their breeding grounds.
The golden mahseer and goonch catfish are among thirty fish species prioritized for global conservation by the UN in a new report, which assessed over 15,000 freshwater migratory fish species. The findings revealed an estimated 81% drop in their populations over the last half-century.
These fish are essential to the livelihoods of millions worldwide, with Dr. Zeb Hogan, a co-author of the report, indicating their vital role in supporting food security for over 200 million individuals. The report highlights the urgent need to address overfishing and habitat loss affecting these species.
Furthermore, the UN proposes adding 30 migratory fish species to a global treaty to improve monitoring and protection during the annual meeting in three years' time. International cooperation is pivotal to curtail the threats faced by migratory fish and ensure their recovery.
