How did the mosquitofish become such a problem for native species of fish across the world?
Naturally, it’s humans' fault.
In the early 1900s, mosquitos were a problem.
As you might expect, this is how the mosquitofish earned its name.
The problem is mosquitofish don’t just eat mosquito larva.
They’ve been an issue ever since, and now scientists may have come up with a solution.
Scientists built the robot to look and move like the natural predator of the mosquitofish: the largemouth bass.
To conduct the study, scientists set up tanks containing mosquitofish and tadpoles, then introduced the robot.
They found the robot was effective in scaring off the mosquitofish.
The mosquitofish exposed to the robot became more focused on fleeing, rather than reproducing.
