California Freshwater Fish Face Extinction: In a concerning update to the International Union for Conservation of Nature’s (IUCN) Red List of Threatened Species, 25% of the world’s freshwater fish population is now in danger of extinction. This revelation is part of the first comprehensive assessment of global freshwater fish. However, local experts, particularly in California, believe the findings may be underestimated.
UC Davis Professor in Fish Ecology, Andrew Rypel, and Director at the Center for Watershed Sciences, expressed that approximately 83% of California’s fish face vulnerability to extinction. The IUCN’s global statistic is alarming, but when applied to California, the threat becomes even more significant.
This issue not only poses an environmental risk but also affects the economy. Scott Artis, Executive Director of the Golden State Salmon Association, highlighted the economic impact, stating that salmon alone contributes $1.4 billion to California’s economy. While some areas show positive signs for salmon, others face high risks, creating a complex scenario.
The factors contributing to the heightened risk of extinction are interconnected with global concerns. Climate change-induced warming of waters, alterations to river flows, invasive species, and overfishing are among the shared challenges identified by both the IUCN and Professor Rypel.
Artis emphasizes the importance of public awareness and active engagement. Salmon’s significance extends beyond the ecological realm, impacting communities, culture, jobs, and businesses. Collaborative efforts from various organizations are underway locally, but Artis stresses the need for stronger actions from state water policymakers.
Professor Rypel underscores the role of science in addressing this crisis and advocates for responsible stewardship of land and waterways. As the alarming statistics call for urgent action, the rallying cry is for collective efforts to protect the diverse fish species, uphold jobs, and preserve the delicate balance of California’s aquatic ecosystems.

Why are freshwater fish going extinct?
Freshwater species face a multitude of threats, including pollution, overfishing, invasive species, disease, dams, and water extraction. Shockingly, 57% of freshwater fish species at risk of extinction are impacted by pollution alone. It’s clear that urgent action is needed to protect these vulnerable creatures and their habitats.
What are the threats to native fish in California?
Estuary alteration, major dams, and agriculture pose the biggest threats to anadromous species, while inland species are threatened by alien species, fire, and hatcheries. These challenges must be addressed to ensure the survival of these species.
What are the two largest freshwater fish extinct?
The International Union for Conservation of Nature (IUCN) has declared the Chinese paddlefish and wild Yangtze sturgeon as extinct, marking the end of a long-standing campaign to preserve these river fish species. This news is a significant blow to conservation efforts, as both species were once abundant in the Yangtze River. However, due to overfishing and habitat destruction, their populations have dwindled to the point of no return. It is a stark reminder of the urgent need to protect our planet’s biodiversity and the delicate ecosystems that support it.
What giant freshwater fish are extinct?
Two of the most notorious river monsters, the Yangtze sturgeon and the Chinese paddlefish, have been declared extinct by scientists. These fish, known as the last giants of the Yangtze, are no longer found in the wild.
