Blockchain could revolutionize tuna fishing - making illegal fishing impossible, protecting fish stocks, and allowing consumers to know with certainty the fish on their plate is sustainably sourced.
“If you have the opportunity as a consumer to know with confidence that you’re buying from a fishery that engages in sustainable and ethical practices, then of course you would want to do that,” says Bubba Cook, WWF Pacific (World Wildlife Fund).

“We have seen heavy depletion in certain stocks, like for instance the Pacific bluefin tuna which is at less than 3% of its historic biomass. That should be a shocking figure for anyone that the historic stock has been depleted to the point where the tank is almost empty,” says Cook.
Illegal, Unreported and Unregulated (IUU) fishing is a major threat to marine biodiversity, the sustainability and balance of marine ecosystems, and to fish populations worldwide.
Illegal catches of skipjack, yellowfin, albacore and bigeye tunas are estimated at $548 million annually.
“If we don’t improve traceability and address illegal fishing then we’re going to see continued declines in our fisheries,” says Cook.

How blockchain can help
By preventing illegal activities, blockchain technology could help tuna stocks to recover and help fisheries worldwide.
Blockchain can track the journey of a single fish, recording information regarding where it was caught and how it was processed.
Once that information enters the system, it is verified by a network of thousands of computers, making it impossible to manipulate or falsify.
In the Pacific Island tuna industry, WWF has partnered with global blockchain venture studio ConsenSys, ICT implementer TraSeable, and tuna fishing and processing company Sea Quest Fiji Ltd to stamp out illegal fishing and slave labour.
If blockchain were to be fully implemented, it would be impossible for any illegal or unreported tuna to enter the market, says Cook.
“Because it’s immutable and tamper-proof, blockchain creates an opportunity for verification and validation. It allows retailers and buyers to understand where [fish] is coming from.

“In time, we’re going to see blockchain become the industry standard for transparency and traceability.
“It’s really exciting to think about the potential for that technology and what it could mean in terms of helping consumers make the right choices and drive things in a sustainable and ethical direction.”
