The Epic History Of The Humble Goldfish

 "OH, WET PET," American poet Ogden Nash wrote in pithy summation of the humble goldfish, whose habitat is, by tradition, a glass bowl anchored by the faux luxury of a gravel-bound ceramic castle. But the reality is more complex, suggests a new book by Anna Marie Roos, a professor of the history of science and medicine at the University of Lincoln, in England.

  In Goldfish, Roos fleshes out the cultural history of this seemingly ho-hum fish, painting it as both common and exotic, scientific research hero and environmental villain, and biogeographic success story. National Geographic spoke by phone with Roos about the fish more formally known as Carassius auratus.

  There are many breeds of goldfish (Carassius auratus). This is a celestial eye goldfish, which has large eyes turned upward.

  As a science historian, you’ve written about esoteric subjects like 17th century mollusk expert Martin Lister. Goldfish seem comparatively banal. I gather there’s a personal backstory.

  I had a pet goldfish named Speedy. I was a geeky scientist at a young age and out of curiosity, touched him. He had really rough scales, so I poured hand lotion in the water to make his scales soft...

  So much for Speedy.

  Yes. In part, I wrote the book out of guilt for Speedy.

  Where do goldfish fit into the animal kingdom?

  Goldfish are basically carp. The Chinese originally bred them to eat. Carp, which are normally grey or green, breed like crazy, and you get variations of colours and shapes. Nature plays around. They have a smattering of pigment cells that are red or gold. A mutation would have suppressed the grey pigment cells, allowing the yellow and red ones to be expressed. Humans took a mutation and made a species of them.

  Let’s follow in their wake as they circulate around the world. We start with China...

  They are domesticated in China more than a thousand years ago and come to Japan around the late 16th century. They go to Europe and beyond as a pet and living ornament for aquaria and fountains via Macao. The first drawing of goldfish in England is by botanist James Petiver in 1711. By the 19th century, they are in the States and mentioned in 1817 in Webster’s Dictionary.

  Losing their mystique and exoticism along the way, no doubt. At one time, you write, the United States government gave them away.

  The first drawing of goldfish in England, above, was done in 1711 by botanist James Petiver.

  In a publicity stunt, from 1884 to 1894, if you were a resident of Baltimore or Washington, D.C, and wrote your congressman, the U.S. Commission of Fish and Fisheries [today the National Marine Fisheries Service] would send you goldfish. Some 20,000 were given away each year before the program was discontinued.

  Other suppliers took up the slack.

  By the turn of the century, the Midwest had huge goldfish farms. Grassyfork Fishery in Indiana produced two million a year. Grassyfork was even a tourist attraction.

  They also have a starring role in more than 40,000 scientific papers. What makes them a good subject for experiments?

  One reason is that they are good at absorbing substances, so they are used in toxicity studies. In the 19th century, for example, they were used to study digitalis dosing. They can regenerate their optic nerve, so they’re of interest in vision studies. Also, they have pretty good memories, and that makes them useful in psychology studies. Their sensitivity to sunlight makes them valuable for looking at skin cancer. They are a good animal model because they breed easily and are cheap.

  There was a brief goldfish-swallowing fad. What prompted that?

  Officially, it started in April 1939, when a Harvard freshman swallowed one on a dare. It largely died out later that year with World War II, as there were other things to think about. Any animal rights activist would be appalled. Animals are not meant for our entertainment. In 2012, a young girl in the United Kingdom was so disturbed about the custom of giving them away as fairground prizes, she started an online petition. In England and Wales, it’s now an offense to give a goldfish as a prize to a minor.

  Tell us about their troublesome side—goldfish as environmental villains.

  Because they’re carp, they’re bottom-feeders and omnivores. They stir up the bottom of a pond or lake in search of prey, making the water turbid and likely to encourage algal growth. Because they are adaptable and can live in a wider range of water temperatures, they outcompete native species. In a head-to-head contest, trout will starve, goldfish will live. That’s what happens when, say, a fisherman uses goldfish as bait, dumps them in a lake, and drives home. They breed and get big. So you get huge goldfish, like the foot-and-a-half one pulled out of Lake Tahoe. In 2015, 3,000 goldfish took over Teller Lake in Boulder, Colorado. The fisheries commission was ready to electro-shock the lake to get them out, when a big flock of white pelicans flew over and picked them off one by one.

  Divine intervention? But you can’t always count on a flock of pelicans to show up...

  The fish has been listed as a nuisance in Colorado, Nevada, New York, North Carolina, Pennsylvania, Oregon. In Alberta, Canada, they have mounted a "Don’t Let It Loose Campaign" and made it an offense to>

  So we might say that the book, in line with Buddhist principles, represents your act of purification for Speedy. Do you think he’s been vindicated?

  Yes. How many goldfish do you know that have a book dedicated to them? If anything, I hope it makes people think about how we use animals as disposable commodities and the assumptions we make about their intelligence. Animals are not put here exclusively for human use.
