Is other fish acceptable?
I prefer to buy slightly more local stuff, i.e. at the very least from the same continent, preferably sub, i.e. Northern Europe.
Not that I don’t eat tinned fish too. What makes those mystery sardines so good? There’s one variety in the shops here which is preserved only with tomato puree and salt, no oil. They’re good.
Oh I have no idea about mercury levels, sorry.
You’d love it here though, salmon is ubiquitous.
