  1. Critically Endangered Species in North America: North America exhibits the highest freshwater fish extinction rate globally, with almost 39% of its species endangered, including the Devils Hole pupfish, Atlantic sturgeon, and various salmon and trout populations.
  2. Global Hotspots for Freshwater Fish Endangerment: Major hotspots for threatened freshwater species include Lake Victoria, Lake Titicaca, Sri Lanka's Wet Zone, India's Western Ghats, and river basins such as the Amazon, Danube, Nile, Ganges, and Mekong.
  3. Primary Threats Driving Freshwater Fish Decline: The main threats to freshwater fish include habitat loss and degradation from dams and agriculture, pollution, overexploitation, invasive species, and climate change, which often act synergistically.
