The molecules they accumulate for this osmotic balancing act are the same molecules that create their distinctive taste — and, eventually, their distinctive smell when they go off.</p> <h2 id="the-osmotic-strategy-why-ocean-fish-taste-better">The Osmotic Strategy: Why Ocean Fish Taste Better</h2> <p>Ocean fish accumulate two main classes of osmolyte: amino acids (sweet glycine, savory glutamic acid) and TMAO (trimethylamine oxide, largely tasteless). Saltwater fish contain three to ten times more free amino acids than beef or freshwater fish, with shellfish especially rich. This explains the inherently savory, complex flavor of ocean seafood.</p>
