Scientists have created a fitness tracker for fish

Scientists have invented Lab-on-a-Fish, a biotelemetric sensor that collects fish physiological data as well as location and environmental data (temperature, pressure, and geomagnetic activity).

The device has miniature dimensions: it weighs 2.4 g with a size of 5.5 x 6.5 x 37 mm, which allows you to attach it to even the smallest underwater inhabitants. Lab-on-a-Fish can collect fish data simultaneously, including fish location, heartbeat, tail movement, and calories burned. All this information is stored on a built-in flash memory and transmitted via a wireless transmitter to scientists, who can identify patterns among all the measurements.

“Our development is a cost-effective way to monitor fish health and behavior that will help preserve aquaculture,” said Daniel Deng, a researcher at the Pacific Northwest National Laboratory (PNNL).

Lab-on-a-Fish will help scientists and managers learn more about the impact of climate change and infrastructure development on the health of aquatic ecosystems. And this, in turn, will form the basis for future strategies for the management and conservation of water resources.
