Why does lemon juice make fish less "fish-smelling"?

Maybe this goes in Cafe Society, but I’m seeking an actual definitive answer, hence…
Putting lemon juice on fish, or in tuna salad, or whatever, seems to reduce the fishy smell . I think this must be because of some chemical reaction, although it could also be a perceptual thing, akin to putting blueing in with the whites to counteract the yellowing. Anyone actually know? Thanks, Dopers. xo,

Amines. The fish has chemical amines that are counteracted by the acid in lemon.

BTW soaking in milk does the same thing…when I make salmon I give it a little watery milk bath and it makes it so much less “fishy.”

Beautiful. Thank you. What a great resource this site has been, for years, and before that, the book.
