Nevada Crayfish Boil: Save the Pupfish

Both pricey delicacies and bug-like garbage eaters, crustaceans are weird creatures, but tasty. Lobster, the most well known of the family, crawl along the bottom of the Atlantic Ocean. Eating anything their big fat claws come upon, including garbage and other lobsters, they only come up in lobster traps and are thankfully, promptly boiled.

Crayfish, a smaller member of the crustacean family that originates in warm southern waters, are lobster's smaller cousins. The eponymous star of the Crayfish boil, Louisiana supplies 95% of the crayfish sold in the United States. In 2007, the Louisiana crayfish harvest was about 54,800 tons, almost all of it from aquaculture. Crayfish were introduced to the warm springs and outflows of Ash Meadows in the early twentieth century. Strangely enough they weren't introduced as a human food source but as food for the introduced bullfrogs. Bullfrog legs were popular in Las Vegas and since bullfrogs eat anything and eat a lot, the populations of endemic pupfish and speckled dace weren't enough to fatten then up. Enterprising farmers introduced the fast reproducing crayfish (which also eat pupfish and dace) to feed the introduced bullfrogs.

Restoration efforts have been very successful in bringing back the pupfish and speckled dace, and
relatively successful in eradicating the bullfrog. Crayfish, not so much. A few days ago I stood on the boardwalk alongside the Crystal Spring outflow and watched helplessly as a crayfish took down, and ate a beautiful blue pupfish. And that brings us to Cold Springs.

Located close to the center of the Ash Meadows National Wildlife refuge, between the eastern mountains and the western Carson Slough, Cold Spring is far from the fault line from which the warmer springs rise. Possibly that's why the water from this spring isn't warm. It's cold, and hence the name. Never-the-less the spring still pumps out huge amounts of water into the desert and as such was a prime candidate for human appropriation. Sometime in the mid 1960s the spring head was enclosed in concrete reservoir, pumps were installed and any native fish life was pumped out onto the alfalfa fields.

Today Cold Spring's water is no longer used for agriculture, but the spring has not yet been restored. The water flows up out of the earth and into that concrete box. The box is crumbling, full of wind blown dirt, lumber, algae and crayfish. Lots of ugly, fat pupfish-eating crayfish. Looking into that murky water, seeing those beady eyes, and spindly pincers wave menacingly back, I thought of the only appropriate response. Nevada Crayfish Boil!

Kelly,
We have been to New Orleans four times now and have yet to have a Mudbug boil and here you go in the desert of Nevada playing Cajun. Great stuff! I hope they were tasty. I am sure they weren't eating the same stuff their southern cousins dine on..
