The fishing industry is infamous because of its unsustainable fishing method. The fishing industry also is known as one of the industries for human rights violations. The United Nations Food and Agriculture Organization (FAO) notes, there are about 50% global marine fisheries resources are used totally, 25% are over developed, about 25% seem to support higher rates of exploitation (FAO, 2005a).
Blockchain technology is used in Pacific Island fishing industry to improve the traceability of tuna. And it helps prevent illegal and unsustainable fishing method. WWF has a cooperation with ConsenSys, a blockchain software technology firm; Sea Quest Fiji LTD, a tuna processing firm; Traseable, and a fisheries traceability tech firm, to start the blockchain project.
On the industry level, it was a headline news that supermarket giant Tesco dropped food maker John West. They cited fishing firms make sure the necessity of using sustainable sources of tuna. Tim Smith, group quality director of Tesco, said: “we hope we can perform the promise of high quality sustainable tuna. We announced that we will take measure to enable our all tuna on the shelves and all brand tuna products meet our requirements”.
They call the project as Bait-to-plate, it will combine radio frequency identification (RFID) tag with QR code and scanner to track the tuna supple chain.
Once workers catch fish and reuse the RFID tag to mark the fish on the boat, the tracking pocess will start. Then check the devices and the location information in the total food product possece will be uploaded automatically to the blockchain. Once fish has been processed, it will be equipped with a cheaper QR code tag on its package. The unique QR code is connected with the blockchain recode related to particular fish and orginal RFID tag. QR code will be used to track fish until they arrive at supermarket shelves.
“Bait-to-plate transparency using the blockchain will mean there is no place to hide for illegal, unreported and unregulated fishing or those operators who use slave labour or impose horrific conditions,” said Dermot O’Gorman, WWF-Australia CEO.
