Spare Parts For Fish Tanks and Aquariums.As anyone who has tried to learn how to ride a bike or to drive a car knows, it is challenging at first," study author Shachar Givon, a graduate student at Ben-Gurion University, said in a statement. "It shows that goldfish have the cognitive ability to learn a complex task in an environment completely unlike the one they evolved in. Not only does this show that fish can drive, but they can also adapt an ecosystem completely different from their own and move through it, reports Audrey Carleton for Vice. This finding suggests that the fish could learn from their environment and adjust accordingly. They all avoided dead-ends and corrected themselves throughout the trials, Vice reports.Īll fish improved their time as the task was repeated. To check and see if the fish were actually navigating to targets and not just memorizing movements to earn a reward, the team changed the FOV's starting position and added decoy targets in different colors.Īll six fish successfully drove toward the visual target and even approached their mark from different angles, suggesting that the fishes understand the world around them, per Ars Technica. Once the goldfish were ready to speed off, the researchers tested their navigational skills by seeing if they could drive to a target. Indeed, the goldfish were able to explore the terrestrial environment, all while avoiding dead-ends and correcting inaccuracies. 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. If a fish was oriented toward the middle of the tank, no movement would occur, reports Aristos Georgiou for Newsweek. To move in a specific direction, the fish must be facing outside the tank in the direction it was moving towards. The fish's movement, orientation, and location were translated into instructions for the wheels of the FOV, allowing the car to move forward, backward, left or right. In 30-minute sessions conducted every two days, the fish were rewarded if they successfully directed the car to a pink-colored target in an enclosed space, Ars Technica reports. Six adventurous goldish were enrolled in "driving school" to learn how to move the FOV before the team collected the data. The algorithm is powered by a small programming computer called Raspberry Pi, Ars Technica reports.īefore the experimental tests could begin, the goldfish needed to learn how to drive the FOV. Based on the camera's signalling, an algorithm moves the tank, allowing the fish to "drive" the car. When the fish bumps into the tank's walls or swims forward, for example, a camera above the tank tracks that movement. ![]() ![]() To determine whether a fish can navigate on dry land, the scientists used a fish-operated vehicle (FOV) with special software and a motion-sensing camera that can monitor where the fish is swimming in its rolling aquarium. ![]() ![]() We trained goldfish to drive a wheeled platform that reacts to the fish’s movement ( ). I am excited to share a new study led by Shachar Givon & w/ Ohad Ben Shahar: Goldfish can learn to navigate a small robotic vehicle on land. The ability to use navigation skills in unfamiliar settings is known as domain transfer methodology, reports Jonathan M. However, researchers do not fully understand whether these navigation skills are specific to the environment an animal evolved to survive in. The study will be published in the February 2022 issue of Behavioural Brain Research.įor survival, animals need navigation skills to find food, seek mates, migrate and more. In a new study, researchers designed a souped-up aquarium on wheels to see if a goldfish can learn to navigate on dry land-and it worked. The experiment is meant to determine whether a fish's navigation skills are universal regardless of their environment. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”īy that logic, how smart is a fish that can learn to drive? A quote often misattributed to Albert Einstein states, "Everyone is a genius.
