Long-Term Efforts Eradicate Invasive Fish to Restore Freshwater Ecosystems in Tasmania and Utah
Two long-term efforts to restore freshwater ecosystems involved eradicating invasive fish species. In Tasmania, nearly 50,000 European carp were removed from Lake Crescent and Lake Sorell over 28 years, leading to their functional eradication by 2025. In Utah, officials used rotenone in 1990 to eliminate over 99% of fish biomass in Strawberry Reservoir, followed by trout restocking and barriers to prevent reinvasion. Both projects aimed to revive native species and improve fishery health through sustained, methodical interventions.
