In 1990, Utah used the world’s largest rotenone treatment on Strawberry Reservoir; over 99% of fish biomass vanished and the rebuilt fishery later produced 715,000 catches a year
- In August 1990, Utah wildlife officials carried out one of the largest chemical fish-removal projects in fisheries history, wiping out almost every fish in Utah’s Strawberry Reservoir to save its collapsing ecosystem.
- The operation, led by the Utah Division of Wildlife Resources (UDWR) and described in publications from the American Fisheries Society and UDWR research reports, removed more than 99 per cent of the lake’s total fish biomass.
- By clearing out the non-native fish, biologists were able to rebuild the food web and create a healthier sport fishery that later produced more than 715,000
