Scottish Mackerel Factories, Norwegian Researchers Track Fish Health via RFID

The Norwegian Institute of Marine Research (IMR) is managing populations of mackerel, as well as some spawning herring in parts of the Northeast Atlantic, using an RFID-based program that tracks the number of fish and their size and weight as they are caught and harvested in Scandinavia and the British Isles. Recently, fish producers in Scotland have joined the growing number of participants in the program to better understand mackerel populations on both sides of the Northeastern Atlantic. Nearly every Scottish mackerel processing factory is now employing low-frequency (LF) RFID readers to identify tagged fish before processing begins, joining factories in Iceland and at the Faroe Islands that were already doing so.
