I was going to recommend kipper, but this says it’s not that much better than tuna. It’s still better, at least in terms of mercury.
This PDF says canned sardines have 1 gram EPA+DHA per 100g, whereas herring has slightly more and tuna is all over the place.
Not very good evidence for kipper vs. sardines (I buy kipper just because I can’t stand sardines, though I’ll look out for salmon now that it’s been mentioned), but either looks to be preferable to tuna.
