300,000 pounds of rock has been stolen from the bottom of the ocean near Alligator Light and Islamorada off the coast of Florida.

The Florida Fish and Wildlife Conservation Commission and the Monroe County Sheriff’s Office wish to hear from anyone who may have seen a boat harvesting the material from the site. If you have any information about this case, please contact FWC, the

Sheriff’s Office or call the Crime Stoppers of the Florida Keys at (800) 346-TIPS. You can also leave an anonymous tip at https://www.tipsubmit.com/.

The stolen rocks belong to Neal Novak, 51, a Miami aquarist who leases the quarter-acre site inshore of Alligator Reef from the federal government to cultivate live rock for the aquarium trade. Unfortunately, Novak hasn’t visited his farm in a year so it is hard to know when the theft took place.

Live rock consists of dead coral rock or quarried rock colonized by a profusion of marine species. Anything from tiny bacteria to large sponges can find a home in and on this type of “living” rock, and rocks covered in colourful coralline algae are especially coveted. Saltwater aquarists use live rock to make their aquariums look more beautiful, make the ecosystem more balanced, and help keep the water quality up in the tank. Live rocks are often colonized by scavenging species that will take care of any left-over food in the aquarium before it gets a chance to foul the water. According to Novak, the wholesale price for quality live rock in Florida is about $3 per pound.

Since the harvest of live rock from the wild can hurt marine environments, Florida banned it in the 1990s and state and federal governments decided to lease barren sea-bottom sites to people interested in aqua-culturing live rock for the aquarium trade.

Novak created his live rock farm by purchasing rock from quarries in south Miami-Dade County and ferrying them to his farm where the rocks have been resting in roughly 20 feet (6 metre) of water until someone took them. The rock pile, which was designated by GPS coordinates, has most likely not been moved by natural forces, because no hurricanes have been reported from the area since 2005 and a second stone pile with immature live rock was left largely intact.

With a wholesale price of $3 per pound, 300,000 pounds of rock can naturally give a tidy little profit for unscrupulous boulder thieves.

“They stole my livelihood,” Novak said. “This is devastating to my whole family. It cost me almost $150,000 to put the rock down and start the business. I spent my life savings to make this work. We could be looking at bankruptcy.”

The catfish L239 has finally been described by science and given a proper name: Baryancistrus beggini. Ichthyologists Lujan, Arce and Armbruster described the species in a paper[1] published in the journal Copeia[2].

Baryancistrus beggini lives in Venezuela and Colombia; in Rio Guaviare and at the confluence of Rio Ventuari and Rio Orinoco. The researchers found the fish in crevices amongst boulders. By analysing stomach contents, they were able to learn that this catfish feeds on periphyton and associated microfauna growing on rocks. (Periphyton is a mixture of algae, heterotrophic microbes, cyanobacteria, and detritus that can be found attached to submerged surfaces, e.g. stones, in most underwater ecosystems.)

In the aquarium trade, L239 is known as Blue panaque or Blue-fin panaque. The name beggini was given by Lujan and his colleagues in honour of Chris Beggin, the owner of an aquarium fish store in Nashville, USA who funded the research. The species has been placed in the genus Baryancistrus, but this might have to be corrected in the future as we learn more about the tribe Ancistrini.

Baryancistrus beggini sports a uniformly dark black to brown base colour with a blue sheen and the abdomen is naked. Along each side of the body you can see a distinctive keel above the pectoral finns; a keel formed by the strongly bent first three to five plates of the midventral series. The body also features two to three symmetrical and ordered predorsal plate rows and the last dorsal-fin ray is connected to the adipose fin.

Wild-caught pets are often recommended against, since the harvest of wild caught specimen may deplete wild populations. In the Brazilian rainforest, the harvesting of popular aquarium species such as cardinal tetras have however helped prevent deforestation and made it possible for local residents to earn a living without resorting to logging, mining, cattle ranching, and slash-and-burn agriculture.

“All this is very counter-intuitive,” says Scott Dowd, an Amazon biologist at the New England Aquarium who has been researching the dark acidic waters of Rio Negro, a major Amazon tributary in Northern Brazil, for the past two decades. “You would think biologists would not want to take fish out of the rainforest. But the fish are the key to miminizing deforestation. The people’s other economic options – timber harvest, cattle ranching and gold mining – are environmental disasters.”
The Rio Negro region has been a major fish exporter for over half a century and 60 percent of local populations rely in this source of income for their sustenance. Since deforestation is known to be detrimental to the survival of financially valuable fish species like the cardinal tetra fish, the Brazilian government has protected the Rio Negro rainforest from logging and burning – at least until now. The situation may be about to change dramatically as more and more aquarium shops switch from wild-caught fish to farm-raised specimens. Wild-caught specimens are used to the dark, soft and highly acidic water conditions of Rio Negro, while farm-raised fish tend to be acclimatized to common tap-water conditions (i.e. clear water that is not very soft or acidic) and therefore easier to keep.

To prevent the market for wild-caught Rio Negro fish from collapsing, Dowd is participating in a “Buy a Fish, Save a Tree” campaign. “The local fisheries look like they are headed for collapse”, Down explains. “But there’s hope that this threat can be addressed. If you ask fish hobbyists if they care about the environment, a very high percentage say they care about it deeply.”

Dowd hopes that the “Buy a Fish, Save a Tree” branding will help Brazilian fish harvesters to benefit from the growing trend of cause labelling, such as Fair Trade and FSC (Forest Stewardship Council).

Another important step in making wild-caught Rio Negro fish a popular alternative to farmed-raised specimens is to adapt them to normal aquarium conditions, and the New England Aquarium is therefore helping local fishermen to efficiently acclimatize wild-caught tetras to a pH-value around 7.0.

Dowd also hope to take advantage of the Internet, by assigning lot numbers to every batch of aquarium fish caught in Rio Negro. “Imagine if you could go online and see a video of the actual fisherman who caught your tropical fish, says Dowd. “I want hobbyists to know directly how their choices can affect people thousands of miles away and how they can make a contribution to saving the rainforest. Things don’t look good, but we can begin to turn all of this around.”
