The Endangered Pupfish – Water Quality Monitoring and EXO.

Using a combination of Meteorological and Water Quality instruments (including an EXO2 sonde), local ecologists hope to bring this unique creature back from the brink of extinction.

The Devils Hole Pupfish became one of the first listed species to the Endangered Species Preservation Act in 1967.

As one of the rarest fish in the world, it can only be found in this one location, and reached an all-time low of 35 observable fish in the Spring of 2013.

Ecologists have employed a battery of instruments, including a payload of Water Quality sensors on an EXO2 platform, to monitor the unique environment of the Pupfish.

Devils Hole as yet remains not fully explored, and there has been much debate over how best to use the water resources it provides.

Protecting the Pupfish and it’s only aquatic home in the desert necessarily pits environmentalists against the needs of local farmers.

Conversationalists, armed with scientific tools like the EXO platform, aim to bring the Pupfish back from the brink.

“They’re beautiful fish,” said Luke Oliver – part of a team of researches raising a secondary batch of the fish just a mile from their natural habitat.

“They’re very inquisitive. Whenever we enter the water to go diving, there are fish that will come up and swing in front of our masks. We can learn from this species.”

  • Devils Hole nowadays sounds like a scary place, but actually it’s really a sanctuary, even though it remains not fully explored.
