Freshwater Fish Conservation Issues

The video discusses the challenges facing freshwater fish in North America, highlighting pollution, habitat loss, invasive species, and climate change as major threats. Research shows a significant number of species are endangered, impacting the fishing industry. The study suggests these issues are part of a global trend, though it does not propose solutions, leaving action to policymakers. Scientists are urged to contribute to conservation efforts.
