What undesirable texture suggests overcooking or poor quality where the structure has completely disintegrated?

Answer

Mushy

Mushy is categorized as a generally negative descriptor specifically indicating that the delicate muscle structure of the fish has suffered complete disintegration, usually as a result of overcooking. When excessive heat is applied, the muscle proteins contract so severely that the internal matrix collapses, leading to an unpleasant, yielding, and often watery texture that lacks any definition or desirable break-apart quality. This is a sign that the cooking process has gone too far beyond setting the proteins into a perfectly separable flake.
