A1
  • noun

  • When you think long lived, you generally think tortoises, redwood trees, and David Attenborough.
  • You don't usually think fish.
  • Fish are simple creatures that tend to meet their end in some other animal's mouth, or floating at the top of your home aquarium.
  • You know, if you're bad at fish keeping.
  • So a hundred year old fish is pretty special.
  • And a whole genus full of fish centenarians borders on astonishing.
  • These are the buffalo fishes, freshwater fish in the genus Ichthyobus.
  • These fish are native to the Great Lakes and the Mississippi River, with some species found as far south as Mexico.
  • Buffalo fish are not native to Arizona, but they do live there because people put them there more than a hundred years ago.
  • In the year of the Great Lakes and Mississippi, Theodore Roosevelt dedicated Roosevelt Dam in his own honor.
  • Because that's the kind of guy he was.
  • And in Nineteen Eighteen, the Bureau of Reclamation stocked the newly created reservoir with buffalo fish.
  • At some point, the buffalo fish made their way from Roosevelt Lake to Apache Lake, another reservoir created by another dam.
  • And they seem to be doing swimmingly there, even though they're living in a desert that they don't belong in, and a lake that also doesn't belong there.
  • But what makes this story weird is that despite their fish out of water existence, they're not only thriving in Apache Lake, they're also thriving
  • for decades.
  • See, buffalo fish are among the world's oldest living animals.
  • At least, these ones are.
  • And by oldest living, I don't mean there's like one or two old buffalo fish telling all the other buffalo fish to stay off their lawn.
  • I mean, centenarians are the norm, when you move them to an artificial lake in Arizona, at least.
  • But based on this population, researchers think hitting the century mark is easily possible for at least three of the five species of buffalo fish.
  • And it's not that the other two don't live that long, it's that research is still pending.
  • And this isn't, like, a common thing in animals.
  • There's only one other animal genus we know of with three or more species that have a maximum age over a hundred.
  • The other one is a marine fish, the rockfishes.
  • What's more, buffalo fish also don't seem to suffer from the effects of age.
  • They do not.
  • seem to physically decline the way that humans do.
  • The bigmouth buffalofish kind of gets better with age, which seems grossly unfair, really.
  • In fact, a twenty twenty one study found that older bigmouth buffalofish tend to have improved immune function and lower stress levels compared to their younger counterparts.
  • This newfound knowledge about how fish can sometimes surpass the lifespan of humans when we have the whole of medical science at our disposal comes to us courtesy of citizen science.
  • The data was collected by citizen scientist anglers fishing in Apache Lake, and we love to see it.
  • It turns out Apache Lake is a better place to do this research than in the fish's native range.
  • That's because buffalo fish are actually at risk of extinction in their native range thanks to overfishing.
  • And it's hard to study longevity when fish get caught and eaten before they have a chance to reach the end of their natural life.
  • natural lifespan.
  • Apache Lake is remote and hard to reach, so the buffalo fish have been able to live there mostly undisturbed.
  • For this study, published in Nature Scientific Reports in the year of the fish, anglers caught, photographed, and released most of the fish, and donated a few others to scientists.
  • For the twenty three fish that were donated, the researchers could establish an age by looking at the otolith, a structure in the inner ear that forms rings as it grows, like trees do.
  • all of the specimens scientists dissected were older than eighty years.
  • And the researchers think some of them are the exact individuals that were stocked in Lake Roosevelt in one thousand eighteen.
  • The photographs were also helpful in establishing an age range for Apache Lake's buffalo fish, since fish older than forty have age spots, and fish older than eighty have more spots that are more well defined.
  • This is, of course, less precise than looking at the otolith, but the fish gets to swim another day.
  • What's also super odd is that all of the fish captured were old.
  • Forty years or older.
  • There don't seem to be a ton of younger individuals.
  • Spawning has not been documented in Apache Lake, even though the scientists checked the individuals they dissected, and, like, everything seemed to be in working order.
  • So the researchers aren't sure if the fish are breeding or not.
  • And if not, why?
  • Though it's worth pointing back at the earlier, neither the fish nor the lake are supposed to be their thing, to suggest that maybe the conditions really aren't right for bringing little buffalo fish into the world.
  • The study's authors feel that their results are a representative sample of the individuals in the lake, and not just something that happened by chance.
  • The fish really do live to be that old.
  • Not only did this study uncover some unknown information about buffalo fish, but it also cost very little to conduct, thanks to volunteer anglers.
  • So this has not only taught us something remarkable about longevity in freshwater fish, but also about the power of citizen science.
  • So if you're good with a rod, maybe it's time to plan a vacation in Arizona.
