Scientists Make Mistakes…and Sometimes They Create New Fish

Science is a process. It follows a method, but it’s all about learning.

And sometimes the best learning comes from mistakes. Everyone makes mistakes, right?

Well last year, scientists at a lab in Hungary had a real OOPS moment.

But after the OOPS comes the learning.

Their hearts were in the right place. At the Research Institute for Fisheries and Aquaculture, they just wanted to try to preserve critically endangered species.

Their focus was the Russian sturgeon, also known as the diamond sturgeon.

As Popular Mechanics explains:

The research team tried to breed more Russian sturgeons via gynogenesis, a type of asexual reproduction in which sperm is necessary but leaves no traces of its DNA behind.

As a result, the offspring ends up with 100 percent maternal DNA (and none from the paternal contributor.)

Easy-peasy, right?

The plan was to use sperm from another endangered species, the American paddlefish.

What came next was completely unexpected.

Instead of merely fertilizing the eggs and then disappearing into the ether, the sperm actually fused with the eggs, creating a hybrid fish, affectionately known as a “sturddlefish.”

SCIENCE, am I right?

This new, uninentional hybrid species had some interesting differences.

Again, Popular Mechanics explains:

Some are close to an even 50/50 genetic split between their two parents, but others appear more sturgeon-like while others have stronger paddlefish traits.

The differences include things like what the fish like to eat.

Sturgeons are carnivores. They feast on smaller sea creatures like mollusks and crustaceans.

Paddlefish, however, prefer plankton, which are not exactly vegetables, but are microscopic organisms quite different from the usual sturgeon diet.

Not all of the hatched hybrids survived, but of those that did, some preferred a sturgeon diet and others preferred the plankton.

According to The New York Times about 100 of this new species survived.

And while the accident has proven an interesting one, the team has no intention of creating any more hybrids.

Sorry little sturddlefish.
