What process leads to the Silky/Buttery mouthfeel often described in fish like salmon?

Answer

High fat content lubricating the muscle fibers

The Silky or Buttery mouthfeel in seafood is primarily a function of the fat content marbled throughout the muscle structure. High-fat fish such as salmon or mackerel possess these intramuscular fats. When these fats are gently heated, they melt slightly, coating the palate and creating a rich, smooth sensation that contributes significantly to the overall eating experience. This lubrication effect reduces friction against the tongue, providing that distinctive, unctuous quality which differentiates them texturally from leaner fish, even if both exhibit good flakiness.
