In Australia, they use a robot to hunt down a dangerous predator

There are two laws of nature that apply to this story: a predator isn’t always gigantic – and this tiny shark proves it – and an invasive species can cause significant damage to ecosystems.

researchersUniversity of Western Australia, who found a solution to the invasion Gambia: a small robot.

Dangerous predator: Gambusia

the Gambia, or “mosquito” in English, is a small freshwater fish, large 3.5 cm if male and 7 cm if female.

It is not a picky creature: it lives in dirty water pools stagnant, e eat anything Standing in front – larvae, eggs of other fish, litter. They often bite the tails of fish or other deities EnterAnd leave them to die.

population The Gulf Of Mexico, in the twentieth century has been introduced into aquatic ecosystems around the world such as Mosquito control methods that carried malaria. She worked in some regions: in Russia, for example, a statue of Gambusia was erected.

in a Australia Whatever goes wrong: Gambusia has multiplied exponentially, becoming Invasive and dangerous All over the country.

robot to solve the situation

the small robot Created by researchers at the University of Western Australia Features of largemouth bass, the natural predator Gambusia.

So just peek at the shape of a largemouth bass It scares Gambusia so much that it keeps them away from their prey. In fact, he threw them into a state of anxiety just like them ability to conceive Significantly decreased.

“There was no need to kill them,” explained Giovanni Poliverino, the author of the research. “It was enough to introduce the fear factor into their daily lives.”

The robot has installed a camera that allows it to distinguish Gambusia from other freshwater species. Researchers put in tank full of water Their robot, six gumboss and six tadpoles. The closer Gambusia gets to the tadpole, The robot moved as if it was attacking. After a 12-week study, scientists found the species was invasive She was more busy escaping from her predator than mating. Males had lower sperm counts, and females produced more fragile eggs. The animals’ weight also decreased.

Now all the prey of this invasive species is safer, and in Australia there were many of them: among them were also the blue-eyed red fin and Edgbaston Goby, Two of the most endangered fish species in the country.
