We have all heard about RFID tagging of animals and pets now chipping is happening to fishes.

RFID is certainly going places, recently in Singapore it has gone under water. The Singapore Underwater World recently announced the latest RFID enabled sea aquarium exhibit. Several species of fish - Arapaima, Alligator Gar, Flower Ray, Pacu, Redtail Catfish, Shovelnose Catfish and Walking Catfish are implanted with RFID. In the past, visitors would have to match fish by their shape and colour to static information wall panels to figure them out. After a couple of tanks, it gets too tedious to find which is which - I know because I was there too.

NOW, when a fish moves within the vicinity of the RFID reader, the information about the fish runs up on the touch-screen display. And of course the visitor can interact further with the device to learn more information about the fish - its really something!
