Underwater Robot Patrol

A robot fish is changing the behaviour, physiology and fertility of “one of the most problematic animals on the planet”. According to a study published in iScience, tests of the robot fish found it essentially scared Gambusia (aka the mosquitofish) “to death”. An international team of biologists and engineers created the robot fish to mimic the largemouth bass, a natural predator of the mosquitofish. The invasive mosquitofish was introduced to Australia over 100 years ago to combat mosquitos and is now considered one of the country’s biggest freshwater threats.
