Summary
The populations of migratory fish, which travel long distances for breeding, are declining due to threats like pollution, overfishing, and habitat loss. A new report by the UN highlights the need to protect these fish species, which are important for both biodiversity and human livelihoods. Scientists have identified 325 migratory fish that need protection, emphasizing 30 key species.
