This year I grew some massive potatoes, and they are great baked. I am working through a list of possible recipes. I came across one that involved making a mayonnaise with tuna as one of the base ingredients. It looked good, it contained capers, lemon juice, egg yolks and a can of drained tuna.
Now, I haven’t bought tuna since the early 1980s. I went to look to see what was in the shops, shelves of different varieties, some in brine, and some in oil. I stopped buying it, and most other commercial catches of white fish, because of worries about fish stocks and environmental damage.
Surely, I thought, things have changed. I looked into whether the tuna fishing industry has improved its practices. Well, only just, in that tuna stocks have recovered a little. However, within the tuna-fishing industry there are problems with sustainable fishing, by-catches, and human rights.
- Bluefin tuna is the largest and most expensive, found in sushi as a delicacy. It is severely overfished and exploited, critically endangered as a species.
- Albacore tuna is most likely to be canned. Overfishing is threatening the populations in the Altantic.
- Skipjack tuna is smaller, and the most commonly consumed. It is overfished in most areas.
- Yellowfin tuna is overfished world-wide. Larger fish in breeding condition are being removed from stocks at a rate that could lead to collapse of their populations.
- Bigeye tuna is similar to yellowfin, and is considered to be overfished world-wide.
The recipe looked delicious, but it is off the menu. How can you help? Read more, don’t eat tuna.
