Researchers have developed robots to identify fish in the sea and help promote more sustainable fishing practices.
Researchers at the University of Haifa have developed an autonomous underwater robot to identify fish in the sea. This Israel21c was told by Professor Roe Diamant.
Thanks to active sonar, he says he can spot fish and estimate their size and biomass.
It will also help fishermen to catch the type of fish they want. After all, they usually throw nets into the water in places where, in their opinion, there may be fish, or pull these nets behind the ship, causing damage to the environment.
“They catch a lot of fish that are not important to them, including turtles, sometimes dolphins and small fish that are not allowed to be caught. The damage to the environment from these methods is very significant. If they have technology that can say : “Looking tuna is the place you have to look, “the fisherman can act in a more sustainable way for the marine system,” explains Diamant.
He noted that he and his team are working to develop a relatively inexpensive fish tracking system so that these sensors can be used to cover large areas.
Acoustic sensors developed by scientists absorb light glare from everything from seabeds to fish. Based on these reflections, the robot’s algorithm tries to understand the environment.
In addition, underwater floats are carried by currents and can control their depth by moving up and down the water, changing their volume.
It was previously reported that Thermetrics developed a robot for researchers from Arizona State University that can breathe, sweat and vibrate.
