Pupfish count at Death Valley NP at 136, substantially higher than in recent years

One of the world’s rarest fish species, the Devils Hole pupfish, has reached a population of 136 observable fish. This high spring season population count at Death Valley National Park follows years of substantially lower spring population counts, which triggered concerns over the chances of survival of this critically endangered fish. 


In the 1970s, 1980s, and 1990s, scientists counted about 200 Devils Hole pupfish in the annual spring season surveys. There was a startling decline in fish numbers starting in the late 1990s.  Biologists were extremely concerned when less than 40 fish were counted in the spring seasons of 2006, 2007, and 2013.
