Measuring blood sugar levels in fish
Researchers from the Tokyo University of Marine Science and Technology have developed an innovative measuring system to determine the blood sugar levels in swimming fish. They inserted a needle with a biosensor on to the head of a tilapia and determined the blood sugar level using a radio-measuring device. The researchers then recorded the data to monitor the fish. The research group plans to use the technology to determine the cholesterol values in swimming sea bream, yellowtail and other fish.
