World First as Endangered Fish Population Recovers; Shortnose Sturgeon Numbers Up 400%

Scientists say for the first time in U.S. and probably global history a fish identified as endangered has been shown to have recovered.

The population of shortnose sturgeon has increased by more than 400 percent in the Hudson River since the 1970s, Cornell University Assistant Professor Mark Bain and colleagues report.

However, researchers note shortnose sturgeon is still endangered in other rivers and will not necessarily be removed from the U.S. endangered species list.

During the past 100 years, 27 species of fish have died off in North America and four have become extinct. The U.S. government currently protects 149 fish species and subspecies and a total of 1,311 species.
