Surgin’ sturgeon



Hudson RiverEndangered fish is no longer… but in a good way

The road to extinction is steep, with travel being much easier in one direction than the other. So findings reported by Main Bain and colleagues at Cornell University, provide welcome news: the shortnose sturgeon Acipenser brevirostrum is alive and well in the Hudson River. With population numbers up by a factor of four since the 1970s, an estimated 60000 fish now do their fishy thing in the river that flows past one of the world’s largest, busiest cities. This is the first time a fish with US Endangered Species Act protection has qualified to be taken off the list for the right reasons. Let’s hope it’s not the last.
