A new fitness tracker that’s very much like a “Fitbit for fish” is revealing new information about fish biology. The first-of-its-kind device uses multiple sensors to wirelessly track what a fish experiences in real-time.
“The Lab-on-a-Fish offers something needed in conservation and aquaculture—a cost-effective way to monitor fish health and behaviour,” said Daniel Deng, a lab fellow and mechanical engineer at Pacific Northwest National Laboratory (PNNL) whose sensor development team collaborated with the battery team lead by Jie Xiao, a laboratory fellow and chemist.
