What is the primary distinction regarding diet that dictates the final taste difference between wild and farmed salmon?

A wild salmon's diet of krill and small fish dictates its final taste, whereas a farmed salmon's taste reflects its feed composition

The difference in diet is one of the most crucial factors separating the flavor experiences of wild versus farmed salmon. Wild salmon consume a natural diet consisting of small fish and krill, which imbues their flesh with a complex, nuanced flavor profile that often leans toward the firmer and cleaner end of the spectrum. In contrast, farmed salmon are typically raised rapidly on commercially prepared pelleted food. Consequently, the resulting taste of the farmed fish directly mirrors the components and composition of these manufactured feeds, leading to a potentially more uniform but less complex flavor structure.
