Extinct No More: Shortnose Cisco Makes a Comeback in Lake Superior

Scientists have made an astonishing discovery: the Shortnose Cisco, a fish species once thought extinct, has been found in Lake Superior.

This unexpected find has excited the scientific community and raised hopes for the conservation of other endangered species.

News Highlights

• Shortnose Cisco, once thought extinct, rediscovered in Lake Superior.
• Overfishing and invasive species led to the fish’s decline.
• Discovery highlights the importance of conservation efforts.
• Scientists are working to determine the fish’s population and distribution.

Background on Shortnose Cisco

The Shortnose Cisco is a native Great Lakes whitefish that was abundant in Lakes Michigan, Huron, and Ontario until the mid-20th century. Overfishing and invasive species, such as sea lamprey and zebra mussels, led to a drastic decline in their population, and the fish was believed to be extinct for nearly 40 years1.

Rediscovery

In 2022, during a routine fish survey, U.S. Geological Survey (USGS) scientists discovered Shortnose Cisco in Lake Superior, a lake where they were not previously known to exist. This unexpected find has been described as a “big, unexpected plot twist” by researchers1.

Significance of the Discovery

The rediscovery of the Shortnose Cisco is a hopeful sign for the health of Lake Superior and the potential for other species believed to be extinct. It highlights the importance of continued research and conservation efforts in preserving biodiversity.

Conservation Efforts

The discovery has prompted discussions about conservation strategies to protect the Shortnose Cisco and its habitat. Scientists are now working to determine the population structure and distribution of the fish in Lake Superior2.

Conclusion

The rediscovery of the Shortnose Cisco in Lake Superior is a remarkable event that underscores the resilience of nature and the importance of ongoing conservation efforts. It offers hope for the recovery of other endangered species and the preservation of our natural ecosystems.
