Opening up a can of tuna yesterday I was wondering ‘where has the rest of this tuna ended up? How long will it be before the whole fish is eaten, and how much will be wasted’?

When I was in fisheries the tuna boats would bring the haul of frozen tuna into port where they’d be weighed, counted, and transferred to a cannery also in port.
A lot were fileted and cut right there too, so not all was straight to can.
Now a lot of the cans stayed fairly together by shipment. So I imagine where a lot code was split across separate pallets or shipments might a single fish be sent to different locations in can form. So I would wager the ‘rest’ of the tuna is at least on the shelf next to… itself.
As far as waste though? Some companies are super diligent about their waste streams. Fish meals and such have resale value. Others leave large amounts of parts and material in their shop floors and just power wash it back into the marine waters even while being fined and penalized by regulators. So mileage varies there.
That’s really insightful, thanks!
Interesting, I suppose a single fish then would generally be shared by a single ‘community’ around whichever store sold those cans. But other fish caught at the same time could potentially be sent to another country entirely.
In terms of waste, I meant more at the consumer level. Seeing as cans last such a long time I’m guessing the wastage would be a lot lower than other more perishable foods…
