These two kinds of fish belong to the kind with better efficacy, but when it comes to taste. Basha fish has a heavier oil content than mullet, so it tastes tender. But if mullet is used as pickled fish, how does it taste? Anyway, it is very common to use mullet as pickled fish in Sichuan now, so let's distinguish this by ourselves. I've also been to the fish owner's pickled fish shop several times. Personally recommend Basha fish.
