Ben-Gurion University researchers teach goldfish to drive
Researchers at the Ben-Gurion University of the Negev say they have taught a goldfish to operate a FOV – a “Fish Operated Vehicle” – and that its ability to drive proves that fish can develop spatial awareness and navigate foreign environments.
In their study , which was published in the peer-reviewed scientific journal Behavioural Brain Research , the fish were put in a fish tank attached to a wheeled apparatus that was navigated by a camera tracking the fish’s movement and a linked computer system that followed the fish’s movement toward the walls of the tank, subsequently moving the vehicle in that direction.
I am excited to share a new study led by Shachar Givon & @MatanSamina w/ Ohad Ben Shahar: Goldfish can learn to navigate a small robotic vehicle on land. We trained goldfish to drive a wheeled platform that reacts to the fish’s movement ( https://t.co/ZR59Hu9sib ). pic.twitter.com/J5BkuGlZ34

The fish were placed on all sides of the room, had to reach a target area marked by a red line and were rewarded with food if they reached their target. Undeterred by numerous decoys and tricks, the fish seemed to improve as the experiment progressed, going from needing up to 30 minutes to find a target to later reaching it within 60 seconds. The study shows that even small fish – often associated with small brain sizes – can learn and adapt at similar speeds to even the smartest mammals.
The fish “were able to operate the vehicle, explore the new environment and reach the target, regardless of the starting point, all while avoiding dead-ends and correcting location inaccuracies,” said study co-authors Shachar Givon of the Ben-Gurion University of the Negev’s Department of Life Sciences and Matan Samina of the Department of Biomedical Engineering.
The fish were tasked to “drive” the vehicle towards a visual target in the terrestrial environment, which was observable through the walls of the tank. Indeed, the goldfish were able to explore the terrestrial environment, all while avoiding dead-ends and correcting inaccuracies. pic.twitter.com/RxPuzFbxkE

“The way space is represented in the fish brain and the strategies it uses may be as successful in a terrestrial environment as they are in an aquatic one,” said the study’s authors. “This hints at universality in the way space is represented across environments.”
The study is among many in the scientific field of animals operating motor vehicles, studied for various reasons, but always entertaining. In 2014, for instance, researchers from the Netherlands led a similar experiment where a goldfish operated an RC (remote controlled) car based on motion captured by a camera device.
Ben-Gurion University of the Negev is renowned for its research departments across medical and scientific fields.

I don't see anything so unusual about this. We teach people how to drive and how to swim. Considering how many automobile accidents there are, I'll bet the fish can be better drivers than a lot of people.
The Goldfish may become very unhappy soon. After all the time and effort they've put in learning how to drive...and before long we will no longer need driving Goldfish as all the cars will be driverless!
They should really teach the fish something useful... like how to trade stocks..or maybe how to write good poetry!
How about teaching them how to cook, although they could get a little touchy about a fish-fry.
I would settle for them leaning how to clean their own bowels.
Seems weird that we live in a world where some parts of it are dying of starvation, disease, and exposure, while other parts are studying the ability of goldfish to drive a vehicle.
I'm going to answer you with a quotation that has been attributed to Benjamin D'Israeli addressing Gladstone in the British Parliament.
"While your ancestors were painting themselves blue and hiding in caves, mine were priests in the Temple of David."
