  • Tuna

    The Poplar Report alerted me to textured vegetable protein in canned tuna, so I decided to look at the current tuna stocks – are we that close to (commercial) extinction? Or is it just the current trend of substituting food ingredients to cheaper or maybe adding weird chemicals for profit?

    If I correctly remember, I had considered tuna overexploited since 1980s and had avoided eating it maybe since junior high school. Moreover, this century has had lurid food fakery scandals including the percentages of mislabeled fish sold in USA, often cheaper fish species being passed for more expensive ones.

    Tunas, both the canned variety and the sushi can contain mislabeled fish, with especially sushi being notorious for fakery (escolar, also sold as ‘white tuna’, can cause severe gastrointestinal distress), the more expensive varieties were more likely to be faked, risk of fakery presumed to grow with demand exceeding the supply, but sometimes also the cheaper species were mislabeled. (in Spain the likelihood the bluefin tuna you ordered in restaurant is something else is on average 73% with seasonal variation based on bluefin fishing season.)

    Now, checking at the state of the tuna stocks, I was surprised to read that conservation methods to protect commercial tuna stock had apparently worked and that depending on report 15 out of 23 stocks or 11 out of 23 stocks monitored were estimated to be fished at sustainable levels in 2024 reports (assuming I correctly understood their summary tables) with 88% of tuna coming from sustainably fished stocks (according to one of the reports). The contrast to 2007 doomsday news is promising, but when looking at the FAO report from 2007, I noticed that even then 13 – 14 out of 23 stocks were fully or moderately harvested, the status of the rest being unknown (3 stocks), overexploited (4 – 5 stocks) or depleted (2 stocks). Maybe the difference between today and then is in the levels of overexploitation reducing?

    Nevertheless, it is nice to read some good news, assuming the tuna statistics are real. However, considering the unreliable climate reporting, I cannot avoid creeping suspicion that the earlier tuna depletion may have been overrated or the current improvements overstated. And maybe I should go to supermarket myself to check if I can find TVP in tuna can, possibly to buy a can of Albacore labeled as sustainably caught.
