ok, you have anchovies, sardines, herring, and mackerel. I have tried sardines, they are ok but I don't get cravings for them. anchovies seem much the same, I never get them on my pizza. I just bought a can of mackerel, I will tell you if I liked it. I am American, we don't eat fish skin or bones
I tried sardines and mackerel years ago - didn't like them at all. In fact, I don't like fish in general. Only exceptions are tuna (which is ok) and cod and coley (which I have as part of fish and chips).
