the answer is not to neutralize the odor - fresh fish should not have any fishy odor. The reason should be for flavor!

Decomposing fish is what causes an odor. Muscle in fish contains a chemical substance called trimethylamine oxide (TMAO) that breaks down when fish decomposes creating aromatic amines called trimethylamine and dimethylamine. The amines create a "fishy" smell.

...and by the way Tango loves smelly sardines!
