Some see fluorescent fish as neon signs of trouble (registration required, quoted text from Yahoo)
Past the shark lagoon and piranha tanks at a Park Ridge pet store dart tiny fish that some consider far more alarming.The glowing red and green swimmers at the Living Sea Aquarium represent the vanguard in the brave new world of genetically engineered pets being sold across the United States. Marketed under such names as "Night Light Fish" and selling for up to $30 apiece, they gleam like inch-long neon signs, thanks to DNA transferred from sea coral and jellyfish.
The fish have existed for years and have been deemed safe by numerous scientists and government agencies. But their recent introduction to the American public--and the lack of regulations covering them--makes some people worry what other manmade critters might follow.
The species that has jump-started the debate over genetically altered pets is the GloFish. Yorktown Technologies, an Austin, Texas-based company, has sold it for a month and rolled it out nationally last week at a suggested price of $5 per fish.The GloFish's red glimmer comes from a coral gene that was added to the embryo of a normal zebra fish, said Alan Blake, Yorktown's chief executive officer. Scientists in Singapore came up with the idea to monitor water quality, trying to get the fish to glow in the presence of toxins.
Yorktown got the right to sell the fish in the U.S., but consulted with scientists and federal agencies for two years before offering it to hobbyists, Blake said.
Where do fluorescent zebra fish come from?Fluorescent zebra fish were specially bred to help detect environmental pollutants. By adding a natural fluorescence gene to the fish, scientists will be able to quickly and easily determine when our waterways are contaminated. The first step in developing these pollution detecting fish was to create fish that would be fluorescent all the time. It was only recently that scientists realized the public's interest in sharing the benefits of this research. We call this the GloFish fluorescent fish.
How common is the use of fluorescent zebra fish in science?
For over a decade, fluorescent zebra fish have been relied upon by scientists worldwide to better understand important questions in genetics, molecular biology, and vertebrate development. Fluorescent zebra fish have been particularly helpful in understanding cellular disease and development, as well as cancer and gene therapy.
Does the fluorescence harm the fish?
No. The fish are as healthy as other zebra fish in every way. Scientists originally developed them several years ago by adding a natural fluorescence gene to the fish eggs before they hatched. Today's GloFish fluorescent fish are bred from the offspring of these original fish.
Back to the Tribune article:
Food and Drug Administration officials said they didn't need to regulate the fish because people would not eat them, and because there was no evidence of an environmental threat. Scientists who reviewed research for California's Fish and Game Commission said the fish, if released into the wild, was unlikely to survive in the state's relatively cold waters.Despite those findings, the commission last month still refused to exempt the GloFish from California's ban on genetically engineered aquatic creatures, imposed in May. Commissioner Sam Schuchat wrote that "creating a novelty pet is a frivolous use of this technology. No matter how low the risk is, there needs to be a public benefit that is higher than this."
Either you own property (i.e., the technology to create the fish), you have agreed to share the ownership, or you don't. Perhaps Yorktown agreed to let the state make some of it's business decisions, allowing it veto power over what's worth putting to market and what isn't.
In this case, the state is asserting it's ownership over the ideas (and therefore, the people and property) in this company and others. That, ladies and gentlemen, is socialism. It's nothing like what people face in other countries, but it is what it is.
The potential environmental effects of the other genetically engineered fish available in the U.S.--a rice fish whose implanted jellyfish DNA causes it to glow green--have proven worrisome elsewhere in the world. The Japanese government last year raised concerns that it could disrupt native species.
Fish may be the first genetically altered creatures to reach the marketplace, but others may not be far behind. A New York company is trying to use gene splicing to create a cat that does not inflame allergies.The cloning expert doing the research, Dr. Jerry Yang of the University of Connecticut, said funding problems have slowed the work but that initial results are promising. He's been able to create embryos that are missing the allergen gene.
He said his project was different from the glowing fish because allergen-free cats can occasionally be found in nature.
"We don't think we're creating anything new," he said. "We're creating existing animals."
No single federal agency regulates transgenic animals, though USDA officials say they are evaluating whether they should play a role. Craig Culp of the Center for Food Safety, an advocacy group that works to curb technologies it says are harmful to health, worries that indifference could allow some altered species to get loose, wreaking havoc on the environment and food supply."We're buying a fish that's been genetically engineered for our amusement and putting it into our kids' bedrooms without thinking of the ethical dimensions," he said. "It staggers the mind to think of what could come down the pike."
Such concerns prompted California to restrict transgenic aquatic animals to research use, and Michigan Gov. Jennifer Granholm has three bills on her desk that would allow the state to outlaw certain genetically engineered creatures."The GloFish is not our issue, but this technology could conceivably create species that would threaten our native fish stock," said spokesman Brad Wurfel of the Michigan Department of Natural Resources.
